At the same time, it also avoids the leakage of important data. Attached Figure Description

[0068] To make the features and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the embodiments of this application.

[0069] In related technologies, conference equipment, as a type of meeting room equipment, is frequently used in meetings and is designed as a public platform for use by different users. The main functions of conference equipment include presenting documents, sharing online content, taking meeting minutes, and conducting remote video calls. In practice, conference equipment is often used to replace traditional projectors and whiteboards, enabling it to more conveniently and efficiently meet various meeting needs.

[0070] In enterprises, conference equipment, as an indispensable shared facility in meeting rooms, often serves the operational needs of various users. These users frequently import various files onto the conference equipment via network transfer or USB drive copying. However, users often neglect to delete these files after attending a meeting. Over time, the data accumulated on the equipment gradually increases, which may not only slow down the equipment but also cause malfunctions, affecting meeting efficiency. More seriously, these leftover files may contain important corporate information, posing a certain security risk.

[0071] To address the existing technical problems, this application provides a data restoration method applied to a conference device. This method determines a conference restoration directory through conference restoration settings data, enabling the conference device to perform data backup processing on the conference restoration directory. This results in target backup data that can be restored, allowing data in the conference restoration directory to be restored after addition, deletion, or modification. Simultaneously, the conference restoration settings data can be used to set data restoration trigger conditions for the conference device. These trigger conditions are associated with preset conference time information for preset conference events. During the conference corresponding to the preset conference event, relevant conference data is present, including conference files displayed and / or generated during the conference. In the conference data storage space, the conference data can be stored in the storage space corresponding to the conference restoration directory, or in a storage space outside the conference restoration directory, or partially stored in the storage space corresponding to the conference restoration directory and partially stored in a storage space outside the conference restoration directory.

[0072] After determining the data restoration trigger conditions, the time association information is determined using the preset meeting time information and the local time of the meeting device. When the time association information meets the data restoration trigger conditions, the meeting device is used to perform data restoration processing using the target backup data. This allows the meeting device to restore data in the current meeting restoration directory based on the data restoration trigger conditions and the target backup data. This solves the technical problem that users often forget to delete these files after attending a meeting, causing the data in the meeting device to gradually accumulate and eventually lead to functional abnormalities that affect meeting efficiency. At the same time, it also avoids the leakage of important data.

[0073] like Figure 1 As shown, Figure 1 This is a schematic diagram illustrating a usage scenario of a conference device provided in an embodiment of this application. The conference device can be an intelligent display device integrating multiple functions. The conference device can be a conference tablet, which may include a display screen, input and output interfaces, a network connection module, a storage module, an operating system, and other tablet hardware and software.

[0074] The display screen in a conference tablet can be a touchscreen integrating display and touch, or a regular display screen that provides display functionality. During meetings, the screen can display documents, images, videos, and other data. Input and output interfaces allow the conference tablet to connect to various external devices, such as projectors, laptops, tablets, and external storage devices, enabling multimedia content sharing and playback, as well as storage capacity expansion. The network connectivity module in the conference tablet supports both wired and wireless connection protocols. Wireless protocols include WiFi (Wireless Fidelity) and Bluetooth, while wired protocols include Ethernet and USB (Universal Serial Bus). Furthermore, the storage module in the conference tablet can be used to save meeting minutes, important documents, and frequently used applications. To meet the needs of different scenarios and users, conference tablets often support compatibility with multiple operating systems, such as Windows, Android, or iOS.

[0075] like Figure 2 As shown, Figure 2 This is a flowchart illustrating a data restoration method provided in an embodiment of this application. The data restoration method is applied to a conferencing device and includes:

[0076] S202: Receive meeting restore settings data and obtain the meeting restore directory based on the meeting restore settings data.

[0077] The meeting restore settings data can be the settings data received by the meeting equipment after a user performs a restore settings operation on the equipment. For example, the meeting equipment may include a data restore application for managing data restore operations on the equipment. Users can perform restore settings operations on the data restore operation page corresponding to the application. Upon receiving the restore settings operation, the data restore operation page generates the corresponding meeting restore settings data, which is then received by the meeting equipment. By allowing users to perform restore settings operations on the data restore operation page of the application, reliance on external devices to send meeting restore settings data can be avoided.

[0078] Of course, meeting reset settings data can also be obtained from external devices (such as servers) via wired or wireless means. For example, the meeting equipment can establish a communication connection with a first external device via wireless communication. After the first external device generates meeting reset settings data, it sends the data to the meeting equipment via wireless communication, and then the meeting equipment receives the data. Alternatively, the meeting equipment can establish a communication connection with a second external device via wired communication. After the second external device generates meeting reset settings data, it sends the data to the meeting equipment via wired communication, and then the meeting equipment receives the data. Since the location of the meeting equipment is usually fixed, obtaining meeting reset settings data from external devices via wired or wireless means avoids the need for users to physically go to the equipment to make the settings, thus providing a more convenient way for users to set up meeting reset settings.

[0079] The conference restore setting data received by the conference equipment is used to configure data restore parameters for the conference equipment. The conference restore setting data may include restore time setting data and conference restore directory setting data. Of course, in some embodiments, the conference restore setting data may also include restore time setting data, conference restore directory setting data, whitelist directory setting data, and backup method setting data.

[0080] For example, the restore time setting data can be a pre-set time point for data restore processing for a preset meeting event. Specifically, this time point can be a certain number of minutes before or after the start of the preset meeting event, so that the meeting device can perform corresponding restore processing before or after the preset meeting event, thereby cleaning up external data imported into the meeting device or data generated in the meeting corresponding to the preset meeting event, and restoring deleted and modified data in the meeting device.

[0081] Furthermore, this time point can also be an adjustable time point, which can be flexibly set. An adjustable time point can be set as a periodic time point, such as a specific time point every day, week, or month. To avoid data restoration time points and interference with users' use of the conferencing equipment, periodic time points can be selected during periods when users use the conferencing equipment less frequently. An adjustable time point can also be set as a specific time point on a specific date, such as a specific time point on a holiday. Since conferencing equipment is usually not used by users on holidays, selecting a specific time point on a holiday for data restoration can effectively avoid interfering with users' use of the conferencing equipment.

[0082] The meeting restore directory settings are used to define the meeting restore directory for the meeting device. Data within this directory is backed up. Typically, the meeting restore directory is a user-accessible file directory. During user use of the meeting device, files are usually added, modified, or deleted. Therefore, if data in the meeting restore directory is tampered with, it can be restored using the target backup data. Specifically, taking Android as an example, the default meeting restore directory is the sdcard directory. Based on the meeting restore directory settings, a specific directory under the sdcard directory can be designated as the meeting restore directory. For example, if the sdcard / Download directory is designated as the meeting restore directory, subsequent backups and data restorations will apply to the Download directory. Furthermore, since users typically do not modify system file directories during normal use of the meeting device, system file directories can be disregarded for the meeting restore directory.

[0083] In some embodiments, the meeting restore settings data may further include whitelist directory settings data. These whitelist directory settings data are used to set a whitelist directory for the meeting restore directory. Data located in the whitelist directory does not need to be backed up or restored. Specifically, if the sdcard / Download directory is used as the meeting restore directory, the application cache directory under sdcard / Download can be set as the meeting whitelist directory to save the application cache data in the application cache directory, thereby preventing the loss of application cache data. Data configured in the meeting whitelist directory can be stored locally on the meeting device, thus preventing data loss.

[0084] In some embodiments, the meeting restore settings data may also include backup method settings data, which is used to set the backup method. The backup method settings data may include backup methods such as local backup, external storage backup (such as backup using an external USB flash drive), and cloud backup (uploading to the cloud for backup).

[0085] S204: Perform data backup processing on the meeting restore directory to obtain the target backup data.

[0086] After receiving the meeting restore settings data, the conferencing equipment can determine the meeting restore directory within the equipment. This directory is typically the user-accessible file directory on the conferencing equipment. Once the meeting restore directory is obtained, data backup is performed on the data within it based on the meeting restore settings data, thus producing the target backup data corresponding to the data in the meeting restore directory.

[0087] S206: Obtain the preset meeting events of the conference equipment, and the preset meeting time information of the preset meeting events.

[0088] Users can pre-schedule and create preset meeting events on the conferencing device. These preset meeting events are essentially meeting events that depend on the conferencing device, such as those created on the device itself. Specifically, preset meeting events can be created based on their preset meeting time information and name. After confirming the existence of a preset meeting event on the conferencing device, the device can retrieve the event information and its preset meeting time to determine the upcoming meeting and the corresponding data restoration trigger conditions.

[0089] S208: Determine the data restoration trigger condition corresponding to the preset meeting time information based on the meeting restoration settings data; wherein, the data restoration trigger condition is used to trigger the restoration process for the meeting equipment.

[0090] After receiving the meeting restore settings data, the conference equipment determines the data restore trigger condition based on the preset meeting time information and the meeting restore settings data on the conference equipment. The data restore trigger condition is a trigger condition associated with a preset meeting event. The data restore trigger condition is used to trigger the restore process for the conference equipment. When the data restore trigger condition is triggered, the target backup data can be used to restore the data in the current meeting restore directory, thereby restoring the data in the meeting restore directory and freeing up the device storage space of the conference equipment.

[0091] Specifically, when determining the data restoration trigger condition based on the preset meeting time information and meeting restoration settings data on the conference equipment, the preset meeting time information of the preset meeting event on the conference equipment can be obtained, such as the meeting start time, meeting end time, and meeting time period. Then, based on the preset meeting time information and the data restoration time information for the preset meeting event in the meeting restoration settings data, the corresponding data restoration trigger condition can be generated. For example, if the meeting start time is scheduled for 14:00, and the data restoration time information for the meeting event is 30 minutes before the meeting start time, then the data restoration trigger condition can be the time point 30 minutes before the meeting start time of 14:00.

[0092] S210: Acquire meeting data related to preset meeting events and store it in the device storage space of the meeting device; wherein, the meeting data includes meeting files displayed and / or generated during the meeting.

[0093] Step S210 can be performed before, after, or during the restoration process; there are no restrictions on this. The meeting data related to the preset meeting event can be the meeting files displayed and / or generated in the meeting corresponding to the preset meeting event.

[0094] Specifically, the meeting files displayed during the preset meeting events can be obtained by the meeting device from the server, sent by the external device via a LAN connection, or copied to the meeting device via an external storage device. The meeting files generated during the preset meeting events can be files created by the user during the meeting, or files generated after the user edits the meeting files displayed during the meeting.

[0095] S212: Determine time association information based on preset meeting time information and the local time of the meeting device, and when the data restoration trigger condition is confirmed to be met through the time association information, restore the meeting device based on the target backup data to release the device storage space of the meeting device.

[0096] Specifically, based on the preset meeting time information and the local time of the meeting equipment, the time difference between the local time of the meeting equipment and the preset meeting time information is determined, such as A minutes before the meeting start time and B minutes after the meeting end time. The time difference between the local time of the meeting equipment and the preset meeting time information is used to obtain time correlation information. Then, it is determined whether the time correlation information matches the data restoration trigger condition. If the time correlation information matches the data restoration trigger condition, the data restoration trigger condition is triggered.

[0097] When the data restoration trigger condition is met, the conferencing device performs a data restoration process using the target backup data to restore the current conferencing restore directory. This restores the data in the current conferencing restore directory using the target backup data corresponding to the current conferencing restore directory. The current conferencing restore directory and the conferencing restore directory are the same directories at different points in time within the conferencing device. Data in the current conferencing restore directory may have been added, deleted, or modified since the user started using the conferencing device.

[0098] The data restoration method provided in this application is applied to a conference device. This method determines a conference restoration directory through conference restoration settings data, enabling the conference device to perform data backup processing on the conference restoration directory, thereby obtaining target backup data that can be restored. This allows data in the conference restoration directory of the conference device to be restored after being added, deleted, or modified. Simultaneously, the conference restoration settings data can be used to set data restoration trigger conditions for the conference device. These trigger conditions are associated with preset conference time information of preset conference events. During the conference corresponding to the preset conference event, relevant conference data is present, including conference files displayed and / or generated during the conference. In the conference data storage space, the conference data can be stored in the storage space corresponding to the conference restoration directory, or in a storage space outside the conference restoration directory, or partially stored in the storage space corresponding to the conference restoration directory and partially stored in a storage space outside the conference restoration directory.

[0099] After determining the data restoration trigger conditions, the time association information is determined using the preset meeting time information and the local time of the meeting device. When the time association information meets the data restoration trigger conditions, the meeting device is used to perform data restoration processing using the target backup data. This allows the meeting device to restore data in the current meeting restoration directory based on the data restoration trigger conditions and the target backup data. This solves the technical problem that users often forget to delete these files after attending a meeting, causing the data in the meeting device to gradually accumulate and eventually lead to functional abnormalities that affect meeting efficiency. At the same time, it also avoids the leakage of important data.

[0100] In one embodiment provided in this application, the preset meeting time information includes the meeting start time, meeting end time, and meeting time period corresponding to the preset meeting event. In step S208, determining the data restoration trigger condition corresponding to the preset meeting time information based on the meeting restoration setting data includes:

[0101] Based on the meeting restoration settings data, determine the data restoration time information for the preset meeting event, and determine the data restoration triggering conditions based on the data restoration time information. The data restoration time information includes at least one of the first time setting information, the second time setting information, and the third time setting information.

[0102] The first time setting information is the time adjustment information for setting the meeting start time; the second time setting information is the time adjustment information for setting the meeting end time; and the third time setting information is the adjustable time adjustment information for the meeting time period.

[0103] For example, in a conferencing device, when a preset meeting event is created, the meeting start time of the preset meeting event has usually not yet arrived. Therefore, a reservation is usually made for the meeting event when it is created in the conferencing device. Thus, the preset meeting time information for the preset meeting event can be obtained. The preset meeting time information may include the meeting start time, meeting end time, and meeting time period corresponding to the preset meeting event. The meeting time period can be understood as the time period composed of the meeting start time and the meeting end time.

[0104] The data restoration time information can be determined by using the meeting restoration settings and preset meeting time information. After obtaining the data restoration time information, the meeting equipment can use it to set the corresponding data restoration trigger conditions. For example, if the data restoration time information is half an hour before the meeting start time of 14:00, then the data restoration trigger condition can be the time point half an hour before the meeting start time of 14:00.

[0105] The data restoration time information may include at least one of the first time setting information, the second time setting information, and the third time setting information. For example, the data restoration time information may include one of the first time setting information, the second time setting information, and the third time setting information; or, the data restoration time information may include any two of the first time setting information, the second time setting information, and the third time setting information; or, the data restoration time information may include the first time setting information, the second time setting information, and the third time setting information.

[0106] The first-time setting information refers to the time information set for the start time of the meeting corresponding to the meeting event. Specifically, the first-time setting information can be a time point X minutes before the start time of the meeting corresponding to the meeting event. Since the data restoration process takes a certain amount of time, in order to provide a better user experience when using the meeting equipment, the time point X minutes before the start time of the meeting corresponding to the meeting event on the meeting equipment can be used as the data restoration time point. Specifically, X can be 10 minutes, 20 minutes, etc., without limitation, and can be set according to the specific scenario.

[0107] The second time setting information is the time information set for the end time of the meeting corresponding to the meeting event. Specifically, the second time setting information can be the time point Y minutes after the end time of the meeting event. After the meeting event ends on the meeting device, the data in the meeting restore directory of the meeting device may be deleted, added, or modified. Setting the second time setting information to the time point Y minutes after the end time of the meeting event facilitates subsequent use of the meeting device and effectively prevents the leakage of the meeting files corresponding to the current user. Y can be 5 minutes, 10 minutes, etc., without limitation, and can be set according to specific scenarios.

[0108] The third time setting information is the adjustable restore time information for the meeting time period. The adjustable restore time information can be flexibly set. It can be set to a periodic time point, such as a specific time point every day, week, or month. In order to avoid data restoration time points and interference with users' use of the meeting equipment, the periodic time points can be selected within the time period when users use the meeting equipment less frequently. The time period when the meeting equipment is less frequently used can be determined based on the meeting time period. The adjustable restore time information can also be set to a specific time point on a specific date, such as a specific time point on a holiday. On holidays, the meeting equipment is usually not used by users, so selecting a specific time point on a holiday for data restoration can effectively avoid interfering with users' use of the meeting equipment.

[0109] This application embodiment determines the data restoration time information for a meeting event by setting meeting restoration settings data, and determines the data restoration triggering conditions based on the data restoration time information. This allows for setting appropriate data restoration time information for the meeting start time or end time corresponding to the meeting event, or using the adjustable restoration time information for the meeting event as the data restoration time information. This enables the meeting device to set the data restoration time information for the meeting event and restore the data, thereby improving the user experience of the meeting device and preventing the leakage of the user's meeting materials.

[0110] like Figure 3 As shown, Figure 3 This is a schematic diagram illustrating a process for determining whether a data restoration trigger condition is met based on a data restoration timer, as provided in an embodiment of this application. Figure 3 As shown, S212 determines time association information based on preset meeting time information and the local time of the meeting device, and confirms that the data restoration trigger condition is met through the time association information, including:

[0111] S302: Determine the time difference information based on the preset meeting time information and the local time of the meeting equipment, and obtain the time correlation information based on the time difference information.

[0112] Specifically, based on the preset meeting time information and the local time of the meeting equipment, the time difference information between the local time of the meeting equipment and the preset meeting time information is determined, such as A minutes before the meeting start time and B minutes after the meeting end time. Time correlation information is obtained by using the time difference information between the local time of the meeting equipment and the preset meeting time information.

[0113] S304: Set a data restoration timer using time-related information and data restoration trigger conditions.

[0114] Among them, the data restoration timer is a type of timer that can be a hardware component in the conferencing equipment or a virtual software module. The data restoration timer is triggered when the time association information in the conferencing equipment matches the data restoration triggering conditions, thereby determining that the conferencing equipment meets the data restoration triggering conditions.

[0115] Time-related information could be A minutes before the meeting start time, B minutes after the meeting end time, etc.; data restoration trigger conditions could be X minutes before the meeting start time, Y minutes after the meeting end time, etc.

[0116] The data restoration timer can be set based on the time difference between time-related information and data restoration trigger conditions. For example, if A is 30 and X is 25, the data restoration timer can be set based on the difference of 5 minutes; if B is 2 and Y is 10, the data restoration timer can be set based on the difference of 8 minutes.

[0117] S306: Trigger the data restoration timer to determine if the conference equipment meets the data restoration triggering conditions; wherein, when the data restoration timer is triggered, the local time corresponding to the conference equipment meets the data restoration time information.

[0118] The data restoration timer counts down after being set. When the countdown ends (countdown is 0), the data restoration timer is triggered. At this time, the time association information and the data restoration trigger condition match, thus confirming that the conference equipment meets the data restoration trigger condition.

[0119] Furthermore, if the data restoration timer is not triggered before the countdown ends, the time association information and the data restoration triggering condition do not match, thus determining that the conference equipment does not meet the data restoration triggering condition.

[0120] In the embodiments provided in this application, a data restoration timer is set by using data restoration trigger conditions and time difference information. When the data restoration timer is triggered, it is determined that the time association information and the data restoration trigger conditions match, thereby determining that the conference device meets the data restoration trigger conditions. When the data restoration timer is not triggered, it is determined that the conference device does not meet the data restoration trigger conditions. This simplifies the judgment logic of whether the data restoration trigger conditions are met, and makes it possible to quickly determine whether the conference device meets the data restoration trigger conditions.

[0121] like Figure 4 As shown, Figure 4 This is a flowchart illustrating another data restoration method provided in an embodiment of this application. Figure 4 As shown, after restoring the conference equipment based on the target backup data in S212, the process also includes:

[0122] S402: When the data restoration application in the conference device is started, when the data restoration application receives the next conference restoration settings data, or when the data restoration application receives the next preset conference event, query the current conference restoration settings data and the current preset conference time information.

[0123] The data restoration application can be used to execute the data restoration method in this application. When the data restoration application is started, the data restoration method corresponding to the conference device runs normally. The starting of the data restoration application includes, but is not limited to, opening the data restoration application, restarting the data restoration application, and automatically starting the data restoration application after the conference device is powered on.

[0124] After the data restore application in the conferencing device receives the meeting restore settings data, when the user updates the meeting restore settings data, they can input the next meeting restore settings data into the data restore application to update the meeting restore settings data. At this time, the data restore application receives the next meeting restore settings data and uses it to update the meeting restore settings data. Of course, users can also schedule new preset meeting events in the conferencing device and then send the next preset meeting event to the data restore application.

[0125] When the data restoration application is activated in the meeting equipment, receives the next meeting restoration settings data, or receives the next preset meeting event, a new round of restoration processing begins. Therefore, it is necessary to query the current meeting restoration settings data and the current preset meeting time information.

[0126] As is easily understood, when the meeting restore settings data is not updated, the current meeting restore settings data remains the meeting restore settings data; when the meeting restore settings data is updated, the current meeting restore settings data becomes the next meeting restore settings data. When the preset meeting event is not updated, the current preset meeting time information remains the preset meeting time information; when the preset meeting event is updated, the current preset meeting time information becomes the preset meeting time information corresponding to the next preset meeting event.

[0127] S404: Obtain the current meeting restore directory based on the current meeting restore settings data; perform data backup processing on the current meeting restore directory to obtain the next target backup data, and use the next target backup data as the target backup data.

[0128] Step S404 is similar to steps S202 and S204, and the relevant descriptions in S202 and S204 can be referred to accordingly. It should be noted that the current meeting restore directory corresponds to the current meeting restore settings data. When the current meeting restore settings data is the same as the meeting restore settings data, the current meeting restore directory is the meeting restore directory. After obtaining the next target backup data, the next target backup data is used as the target backup data; that is, the current target backup data is updated and replaced using the next target backup data.

[0129] S406: Set a data restoration timer based on the current meeting restoration settings data and the current preset meeting time information. When the data restoration timer is triggered, determine that the meeting device meets the current data restoration trigger conditions.

[0130] After determining the current meeting restore settings data and the current preset meeting time information, the current data restore trigger conditions corresponding to the current preset meeting time information can be determined using the current meeting restore settings data. Then, the current data restore time information for the current preset meeting time information can be determined based on the current meeting restore settings data. The current time difference information can be determined based on the current data restore time information and the local time of the meeting device. The current time correlation information can be obtained based on the current time difference information. Then, the data restore timer can be updated using the current time correlation information and the current data restore trigger conditions. When the data restore timer is triggered, it is determined that the meeting device meets the current data restore trigger conditions.

[0131] S408: Perform the steps to restore the conference equipment based on the target backup data.

[0132] The specific details of restoring the conference equipment based on the target backup data in S408 can be found in the relevant description of S212. This step is used to execute the restoration process of the conference equipment based on the target backup data in S212.

[0133] In the embodiments provided in this application, when it is confirmed that the data restoration application in the conference device has started, the data restoration application has received the next conference restoration setting data, or the data restoration application has received the next preset conference event, a new round of restoration processing is entered. Therefore, it is necessary to query the current conference restoration setting data and the current preset conference time information. Then, the data restoration timer is set using the current conference restoration setting data and the current preset conference time information, thereby updating the timing data in the data restoration timer. When the data restoration timer is triggered, the conference device meets the current data restoration trigger condition. At this time, the step of restoring the conference device based on the target backup data is executed. That is, every time a new round of restoration processing is entered, the data restoration timer is updated and the corresponding restoration processing is performed.

[0134] like Figure 5 As shown, Figure 5 This is a schematic diagram illustrating a process for determining whether a conference device meets the current data restoration triggering conditions, as provided in an embodiment of this application. Figure 5 As shown, in S406, a data restoration timer is set based on the current meeting restoration settings data and the current preset meeting time information. When the data restoration timer is triggered, it is determined that the meeting device meets the current data restoration trigger conditions, including:

[0135] S502: Determine the current data restoration time information corresponding to the current preset meeting time information based on the current meeting restoration settings data, and determine the current data restoration trigger condition based on the current data restoration time information; wherein, the current data restoration trigger condition is used to trigger the restoration process for the meeting equipment.

[0136] The current preset meeting time information includes the meeting start time, meeting end time, and meeting time period corresponding to the current preset meeting event. When the preset meeting event is updated by the next preset meeting event, the current preset meeting event becomes the next preset meeting event; when the preset meeting event is not updated by the next preset meeting event, the current preset meeting event remains the preset meeting event.

[0137] Based on the current meeting restore settings data, determine the current data restore time information for the current preset meeting event, and determine the current data restore triggering condition based on the current data restore time information for the current preset meeting event. The current data restore time information for the current preset meeting event includes at least one of the fourth time setting information, the fifth time setting information, and the sixth time setting information.

[0138] In this embodiment, the fourth time setting information is the time adjustment information for setting the meeting start time, the fifth time setting information is the time adjustment information for setting the meeting end time, and the sixth time setting information is the adjustable time adjustment information for the meeting time period.

[0139] S504: Determine the current time difference information based on the current preset meeting time information and the local time of the meeting equipment, and obtain the current time association information based on the current time difference information.

[0140] Specifically, based on the current preset meeting time information and the local time of the meeting equipment, the time difference information between the local time of the meeting equipment and the current preset meeting time information is determined, such as C minutes before the meeting start time and D minutes after the meeting end time. Time correlation information is obtained by using the time difference information between the local time of the meeting equipment and the current preset meeting time information.

[0141] S506: Update the data restoration timer using the current time association information and the current data restoration trigger conditions.

[0142] The current time-related information can be A minutes before the meeting start time, B minutes after the meeting end time, etc.; the current data restoration trigger condition can be X minutes before the meeting start time, Y minutes after the meeting end time, etc.

[0143] The data restoration timer can be set based on the time difference between the current time association information and the current data restoration trigger condition. For example, if A is 30 and X is 25, the data restoration timer can be set based on the difference of 5 minutes; if B is 2 and Y is 10, the data restoration timer can be set based on the difference of 8 minutes.

[0144] S508: Trigger the data restoration timer to determine if the conference equipment meets the current data restoration triggering conditions; wherein, the local time of the conference equipment meets the current data restoration time information.

[0145] The data restoration timer counts down after being set. When the countdown ends (countdown is 0), the data restoration timer is triggered. At this time, the current time association information and the current data restoration trigger condition are matched. Therefore, it is determined that the conference equipment meets the current data restoration time information, that is, it meets the current data restoration trigger condition.

[0146] Furthermore, if the data restoration timer is not triggered before the countdown ends, the current time association information and the current data restoration triggering condition do not match. Therefore, it is determined that the conference device does not meet the current data restoration time information, i.e., it does not meet the current data restoration triggering condition.

[0147] In the embodiments provided in this application, a data restoration timer is set by using the current data restoration trigger condition and the current time difference information. When the data restoration timer is triggered, it is determined that the current time association information and the current data restoration trigger condition match, thereby determining that the conference device meets the current data restoration trigger condition. When the data restoration timer is not triggered, it is determined that the conference device does not meet the current data restoration trigger condition. This simplifies the judgment logic of whether the current data restoration trigger condition is met, and makes it possible to quickly determine whether the conference device meets the current data restoration trigger condition.

[0148] In one embodiment provided in this application, when the restoration process is completed, a first restoration time point corresponding to the completion of the restoration process is determined, and the current restoration time point is updated based on the first restoration time point; wherein, the current restoration time point before the update is the previous restoration time point, and the previous restoration time point is the second restoration time point corresponding to the completion of the previous restoration process.

[0149] During the process of restoring data in the current meeting restore directory based on the target backup data, there are situations where the data restore timer is not triggered or the restore process is abnormally interrupted due to abnormal circumstances. Therefore, in order to determine whether the current restore process has been successfully executed, the first restore time point corresponding to the completion of the restore process can be determined.

[0150] Then, the current restoration time point is updated using the first restoration time point, making the current restoration time point the same as the first restoration time point. That is, the current restoration time point is updated every time the restoration process is complete. It should be noted that each time the restoration process is complete, a corresponding completion command is generated, which instructs the conferencing equipment to update the current restoration time point using the first restoration time point.

[0151] As is easily understood, the current restore time point before the update is the previous restore time point, which is the second restore time point determined when the previous restore process was completed. When the restore process is not completed, that is, when there are abnormal situations such as the data restore timer not being triggered or the data restore process being abnormally interrupted (the conference equipment is turned off), the current restore time point will not be updated. Therefore, the current restore time point is the second restore time point determined when the previous restore process was completed.

[0152] Subsequently, in response to the start operation of the data restoration application in the conference equipment, the current restoration time point recorded in the data restoration timer can be obtained. If the current restoration time point is behind the data restoration time information, the steps of restoring the conference equipment based on the target backup data are executed.

[0153] In cases where the data restoration timer fails to trigger due to abnormal circumstances or the restoration process is abnormally interrupted, the data restoration application in the conference equipment may either run abnormally or stop running. In such cases, a start operation can be initiated for the data restoration application in the conference equipment.

[0154] In response to the startup operation of the data restoration application in the conference equipment, the data restoration time information of the data restoration timer set based on the data restoration trigger condition is obtained. The current restoration time point is compared with the data restoration time information. When the current restoration time point is behind the data restoration time information, it indicates that the data restoration timer has not been triggered or the restoration process has been abnormally interrupted. Therefore, the step of restoring the conference equipment based on the target backup data is executed again to complete the restoration process and avoid the risk of data leakage due to the failure of the restoration process.

[0155] In the embodiments provided in this application, the current restoration time point is updated according to the first restoration time point when the restoration process is completed. This allows for a determination of whether the restoration process was successfully completed based on the current restoration time point. After the data restoration application starts, the current restoration time point recorded by the data restoration timer and the data restoration time information can be compared to determine if the restoration process was successful. If the current restoration time point lags behind the data restoration time information, it indicates that the data restoration timer was not triggered or the restoration process was abnormally interrupted. Therefore, the step of restoring the conference device based on the target backup data is executed again to complete the restoration process and avoid the risk of data leakage due to unsuccessful restoration.

[0156] like Figure 6 As shown, Figure 6 This is a schematic diagram illustrating a process for obtaining target backup data, provided as an embodiment of this application. Figure 6 As shown, the meeting restore directory includes a meeting whitelist directory and a meeting restore list directory. In step S204, data backup processing is performed on the meeting restore directory to obtain the target backup data, including:

[0157] S602: Obtain the target data backup method for the meeting restore directory from the meeting restore settings data.

[0158] The meeting restore settings data can also include restore time settings, meeting restore directory settings, whitelist directory settings, and backup method settings. Based on the meeting restore directory settings, the meeting restore directory in the meeting device can be determined. Based on the whitelist directory settings, the meeting whitelist directory within the meeting restore directory can be determined. Data in the meeting whitelist directory does not need to be backed up or restored. The non-meeting whitelist directories in the meeting restore directory are the meeting restore list directories; target data in the meeting restore list directories are used for subsequent backup and restoration.

[0159] The backup methods for target data in the meeting restore settings include local backup, external storage backup (such as backup using an external USB flash drive), and cloud backup (uploading to the cloud for backup).

[0160] S604: Based on the target data backup method, perform target data backup processing on the target data corresponding to the meeting restore list directory to obtain target backup data.

[0161] When the target data backup method is local backup, a hidden directory with the same name as the target data can be created in the sdcard directory on the conference device. The directory name is ".reset", and the filenames are preceded by a "." to indicate that it is a hidden directory. Users will not be able to see it in file management applications. In this case, the backup directory path corresponding to the target backup data is sdcard / .reset. Then, the files in the conference restore directory are copied to the sdcard / .reset directory. The advantage of local backup is that it does not require additional storage space; when the backup data is small, the storage space occupied is negligible.

[0162] When the target data backup method is external storage backup, if the conference equipment is connected to external storage such as a USB flash drive or external hard drive, the target data corresponding to the conference restore list directory can be saved to the root directory of the external storage, also named .reset. The advantage of external storage backup is that it can back up a relatively large amount of data and does not depend on the network.

[0163] When the target data is backed up using cloud backup, the target data corresponding to the meeting restore list directory can be uploaded to the server for backup. When restoration is needed, the files are retrieved from the server. The advantage of cloud backup is that it does not occupy device storage space. At the same time as uploading the backup, the corresponding file level data is saved for comparison during restoration.

[0164] In addition, prior to S604, a check could be performed to ensure the existence of the meeting restore list directory and that it was a folder type. If this was not the case, a backup failure report with the reason for failure would be submitted. Upon successful backup, a success report would be submitted, and the backup time point would be saved locally.

[0165] In the embodiments provided in this application, the target data corresponding to the meeting restore list directory in the meeting restore directory is processed by the target data backup method to obtain the target backup data. This allows for targeted data backup based on the target data backup method, avoiding redundant data backup.

[0166] like Figure 7 As shown, Figure 7 This is a schematic diagram illustrating a data restoration process provided in an embodiment of this application. Figure 7 As shown, S212 performs a restoration process on the conference equipment based on the target backup data to free up the device storage space of the conference equipment, including:

[0167] S702: Obtain the first index variable and the second index variable. The first index variable points to the restore list directory in the current meeting restore directory, and the second index variable points to the target backup data.

[0168] Specifically, a first index variable and a second index variable can be pre-created. The first index variable is set to point to the restore list directory in the current meeting restore directory so that it can access the target data corresponding to the restore list directory. The second index variable is set to point to the target backup data so that it can access the target backup data. An index variable is typically a sequence of numbers or symbols used to quickly locate the information it points to within a data structure (such as an array, list, or database).

[0169] S704: Based on the first index variable, traverse the target data corresponding to the restore list directory to determine the operation time information corresponding to the currently traversed node file; based on the second index variable, determine the backup node file corresponding to the node file in the target backup data, and determine the backup time corresponding to the backup node file.

[0170] The process involves determining the target data corresponding to the restore list directory based on the first index variable. Then, each node file in the restore list directory is traversed, similar to tree traversal, but here using a depth-first search. During traversal, the operation time information corresponding to the currently traversed node file is determined, including the creation and modification times of the node file. Simultaneously, the backup node file corresponding to the node file in the target backup data can be determined using the second index variable. Then, the backup time corresponding to the backup node file is obtained; the backup time refers to the time when the backup node file was backed up. The first and second index variables can be located in the same directory for easy searching.

[0171] S706: Performs file restoration on node files based on operation time information, backup time, and backup node files to free up device storage space for the conference equipment.

[0172] The process involves obtaining the operation time, backup time, and backup node file, then using these information to restore the node files. It's important to note that for each node file traversed, its corresponding operation time, backup time, and backup node file are determined, and then used for file restoration. Once all node files in the target data have been traversed, the initial data restoration for the current restore list directory is complete. At this point, both newly added and modified files in the restore list directory have been restored.

[0173] In the embodiments provided in this application, a first index variable points to the restore list directory within the restore list directory, and a second index variable points to the target backup data, thereby enabling rapid retrieval of the target data and target backup data corresponding to the current restore list directory. Then, the target data corresponding to the current restore list directory is traversed to determine the operation time information corresponding to the currently traversed node file, as well as the backup node file and its backup time. Finally, the node file is restored using the operation time information, backup time, and backup node file, completing the initial data restoration for the current restore list directory. At this point, both newly added and modified files in the restore list directory are restored, thereby freeing up the device storage space of the conferencing equipment.

[0174] like Figure 8 As shown, Figure 8 This is a schematic diagram illustrating a process for restoring node files, provided as an embodiment of this application. Figure 8 As shown, S706 performs file restoration processing on node files based on operation time information, backup time, and backup node files, including:

[0175] S802: Obtain the creation and modification times of node files based on operation time information.

[0176] In the file system, operation time information includes creation time and modification time. When a user adds a file, the newly created file will have its creation time and modification time initialized. When a user modifies a file, the modified file will have its modification time updated, but the creation time will remain unchanged.

[0177] S804: If the creation time is later than the backup time, the node file is determined to be a newly added file and the newly added file is deleted.

[0178] When the creation time is later than the backup time, it indicates that the node file was created in the current meeting restore directory after the target data backup process. Therefore, the node file is determined to be a new file, and in order to restore it to the meeting restore directory, the new file is deleted.

[0179] S806: When it is confirmed that the backup time is later than the creation time and the modification time is later than the backup time, the node file is determined to be a modified file, and the modified file is replaced based on the backup node file.

[0180] Specifically, when the backup time lags behind the creation time, it indicates that the node file was a file in the meeting restore directory before the target data backup process. Conversely, when the modification time lags behind the backup time, it indicates that the node file was modified after the target data backup process. Therefore, the node file is identified as a modified file. To restore the meeting restore directory, the backup node file is used to replace the modified file.

[0181] Specifically, once the node file is determined to be a modified file, a file with the same path in the .reset directory can be used to overwrite it. If the node file has been renamed, the corresponding file cannot be found in the .reset directory for restoration, but it can be considered that the original file has been deleted and a new file has been created, which does not affect the restoration effect.

[0182] Furthermore, for cloud backups, since it's not possible to directly point to the .reset directory in the cloud, a list of files to be downloaded can be filtered based on the directory hierarchy data saved during backup. The download addresses for these files can then be queried from the server, and the downloaded files can be saved to the corresponding local path. This allows for quick local retrieval and avoids consuming excessive local storage space. Simultaneously, the success or failure of the restoration is reported.

[0183] In the embodiments provided in this application, when the creation time is later than the backup time, it indicates that the node file was created in the current meeting restore directory after the target data backup process. Therefore, the node file is determined to be a newly added file, and the newly added file is deleted. When the backup time is later than the creation time, it indicates that the node file was a file in the meeting restore directory before the target data backup process. At the same time, when the modification time is later than the backup time, it indicates that the node file was modified after the target data backup process. In order to restore the meeting restore directory, the modified file is replaced by the backup node file.

[0184] like Figure 9 As shown, Figure 9 This is a schematic diagram illustrating a file recovery process provided in an embodiment of this application. Figure 9 As shown, the method includes:

[0185] S902: Determine the first file list of the traversed data corresponding to the current restore list directory, determine the reference backup data corresponding to the traversed data from the target backup data, and determine the second file list of the reference backup data.

[0186] Specifically, after traversing all leaf nodes (nodes without child nodes) and before returning to the parent file, the first file list corresponding to that leaf node can be determined. Then, the reference backup data corresponding to that traversed data can be determined from the target backup data, and the second file list of the reference backup data can be obtained. The first file list is the file list information from the traversed data, and the second file list is the file list information from the reference backup data.

[0187] S904: Determine the target file to be deleted corresponding to the first file list based on the second file list.

[0188] Specifically, the first file list and the second file list are compared, and the second file list is used to find the target file to be deleted corresponding to the first file list.

[0189] S906: Determine the backup recovery file corresponding to the target deleted file from the reference backup data, and perform file recovery processing on the traversed data based on the backup recovery file.

[0190] After identifying the target deleted file, the corresponding backup recovery file is found in the reference backup data, and then the backup recovery file is used to perform file recovery processing on the traversed data.

[0191] In the embodiments provided in this application, a first file list and a second file list are compared, thereby using the second file list to find the target deleted file corresponding to the first file list. After the target deleted file is determined, the backup recovery file corresponding to the target deleted file is found in the reference backup data. Then, the backup recovery file is used to perform file recovery processing on the traversed data, so that the data recovery processing is also completed synchronously after the target data corresponding to the current restore list directory is traversed.

[0192] like Figure 10 As shown, Figure 10 This is a schematic diagram of a data recovery device provided in an embodiment of this application. The data recovery device 1000 is applied to a conference device and includes:

[0193] The receiving module 1010 is adapted to receive meeting restore setting data and obtain a meeting restore directory based on the meeting restore setting data;

[0199] Optionally, the preset meeting time information includes the meeting start time, meeting end time, and meeting time period corresponding to the preset meeting event; the determination module 1040 is also adapted to:

[0200] Based on the meeting restoration settings data, determine the data restoration time information for the preset meeting event, and determine the data restoration triggering conditions based on the data restoration time information.

[0201] The first time setting information is the time adjustment information for setting the meeting start time; the second time setting information is the time adjustment information for setting the meeting end time; and the third time setting information is the adjustable time adjustment information for the meeting time period.

[0202] Optionally, the restore module 1060 includes:

[0205] The triggering unit is adapted to trigger the data restoration timer and determine that the conference equipment meets the data restoration triggering conditions; wherein, when the data restoration timer is triggered, the local time corresponding to the conference equipment meets the data restoration time information.

[0206] Optionally, the data recovery device 1000 further includes:

[0207] The query module is suitable for querying the current meeting restoration settings data and the current preset meeting time information when confirming that the data restoration application in the conference device has started, received the next meeting restoration settings data, or received the next preset meeting event.

[0208] The data backup module is suitable for obtaining the current meeting restore directory based on the current meeting restore settings data; performing data backup processing on the current meeting restore directory to obtain the next target backup data, and using the next target backup data as the target backup data;

[0209] The judgment module is suitable for setting a data restoration timer based on the current meeting restoration settings data and the current preset meeting time information. When the data restoration timer is triggered, it determines that the meeting device meets the current data restoration triggering conditions.
