[0051] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is only one of the embodiments consistent with the present disclosure. Therefore, it is not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0052] The key invention point of the present disclosure is that it adopts a data tiered storage strategy based on user access permissions to optimize data management. In the receiving terminal, the system dynamically adjusts the access control of different types of data according to the user's permissions to ensure that the user can only access the data authorized by the user. In the receiving terminal, the data is divided into different storage levels according to the user's permissions and the access frequency of the data: the high-performance storage layer is used to store high-frequency access data, the medium-performance storage layer is suitable for medium-frequency access data, and the low-cost storage layer is used to store low-frequency access data.
[0053] Figure 1 The basic flowchart of the preset strategy of the terminal management platform in the embodiment of the present disclosure is shown. As shown in Figure 1 The user access permissions and data storage levels can be preset on the terminal management platform. Among them, the user access permissions include read permission, write permission, no permission and execute permission, and the data storage levels include hot data, warm data and cold data.
[0054] Figure 2 The basic flowchart of the implementation of data tiered storage for the external device of the terminal in the embodiment of the present disclosure is shown. As shown in Figure 2 The implementation method of the data tiered storage is briefly described.
[0055] Step 1, the terminal management platform presets the user's access permissions and data storage levels.
[0056] Step 2, the receiving terminal user inserts an external storage device.
[0057] Step 3, the sending terminal automatically detects and identifies the external storage device.
[0058] Step 4, according to the preset strategy, verify the current user access permissions (read permission, write permission, no permission and execute permission), and determine the storage level according to the data storage level (hot data, warm data, cold data).
[0059] Step 5, get the data access frequency, divide and store the data according to the access frequency in the corresponding storage level: high-frequency access data is stored in the high-performance layer, medium-frequency access data is stored in the medium-performance layer, and low-frequency access data is stored in the low-cost layer.
[0060] Specifically, for the external storage device, the storage layer is divided according to the following rules:
[0061] High-performance layer: used to store hot data, which uses SSD or high-speed HDD, suitable for high-frequency access data.
[0062] Medium-performance layer: used to store warm data, which uses medium-end HDD or SSD, and stores medium-frequency access data.
[0063]
[0063] Low-cost tier: used for storing cold data, which adopts traditional HDD or tape library, suitable for data with low frequency of access.
[0064] In this patent application, data is classified according to access frequency, and the access frequency is set as follows:
[0065] When the access frequency reaches X, it is classified as hot data, for example, when the data access frequency is more than 10 times per day, the access frequency is less than Y, it is classified as cold data, for example, when the data access frequency is less than 1 time per month.
[0066] When the access frequency is between X and Y, it is classified as warm data, for example, when the data access frequency is between 1 time per month and 10 times per month.
[0067] After determining the data type, the storage tier corresponding to different data types can be determined, specifically, hot data is stored in a high-performance tier, warm data is stored in a medium-performance tier, and cold data is stored in a low-cost tier.
[0068] Step 6, the user can only access data matching his / her access rights, ensuring data security.
[0069] Figure 3 A flowchart of a data storage method for zero-terminal peripheral devices provided by the embodiments of the present disclosure. As shown in the figure, the method is applied to a sending terminal, which includes: Figure 3
[0070] Step 301, starting an automatic detection program when receiving notification information; wherein the notification information is used to indicate that an external storage device is inserted into the current receiving terminal user;
[0071] In this step, after the receiving terminal and the sending terminal establish a connection, the receiving terminal software detects the new device and sends notification information to the sending terminal when the terminal user inserts the external storage device SSD. The sending terminal will automatically start the detection program when receiving the notification information sent by the receiving terminal.
[0072] Step 302, when the automatic detection program identifies that the external storage device is a legal storage device, sending request information to the terminal management platform, the request information is used to verify the access rights and data storage level of the current receiving terminal user;
[0073] In this step, when the sending terminal identifies that the inserted new external device is a legal storage device, the sending terminal will request the terminal management platform to verify the access rights and data storage level of the terminal user.
[0074] Step 303, receiving the verification result returned by the terminal management platform, and determining the access rights and data storage level of the current receiving terminal user according to the verification result;
[0075] In this step, the sending terminal receives the verification result returned by the terminal management platform, and determines the access permission and data storage level of the current receiving terminal user according to the verification result.
[0076] Step 304, determining the preset storage level of the target data according to the predicted access frequency of the target data;
[0077] In one embodiment, as shown in the figure, Figure 4 determining the preset storage level of the target data according to the predicted access frequency of the target data includes:
[0078] Step 401, obtaining the predicted access frequency of the target data;
[0079] Step 402, determining the type of the target data according to the predicted access frequency of the target data;
[0080] In one embodiment, determining the type of the target data according to the predicted access frequency of the target data includes:
[0081] If the access frequency of the target data is greater than a first preset value, the target data is divided into hot data;
[0082] If the access frequency of the target data is less than a second preset value, the target data is divided into cold data; wherein the second preset value is less than the first preset value;
[0083] If the access frequency of the target data is between the second preset value and the first preset value, the target data is divided into warm data.
[0084] In this embodiment, for example, data with a data access frequency of more than 10 times per day is divided into hot data, data with a data access frequency of less than 1 time per day is divided into cold data, and data with a data access frequency of between 1 time per month and 10 times per month is divided into warm data.
[0085] Step 403, determining the preset storage level of the target data according to the type of the target data.
[0086] In one embodiment, determining the preset storage level of the target data according to the type of the target data includes:
[0087] If the target data is divided into hot data, the preset storage level of the target data is determined to be a high-performance layer;
[0088] If the target data is divided into cold data, the preset storage level of the target data is determined to be a low-performance layer;
[0089] If the target data is hot data, it is determined that the preset storage level of the target data is a medium performance level.
[0090] Step 305: When the preset storage level of the target data is consistent with the data storage level of the current receiving terminal user, the current receiving terminal user is controlled to open the external storage device, and the target data is displayed.
[0091] In one embodiment, when the preset storage level of the target data is inconsistent with the data storage level of the current receiving terminal user, the method comprises:
[0092] A notification message of "current storage device level and data storage level do not match" is returned to the current receiving terminal user.
[0093] Optionally, before the request information is sent to the terminal management platform, the method further comprises: Figure 5 The method further comprises:
[0094] Step 501: ID information of the external storage device is acquired.
[0095] Step 502: The automatic detection program identifies that the external storage device is a legal storage device according to the ID information of the external storage device.
[0096] Step 503: The ID information of the external storage device is recorded in log information.
[0097] In this embodiment, whether the external storage device belongs to a legal device can be determined through the ID information of the external storage device. The device ID information is usually a serial number, which serves as a unique identifier of the storage device and can be used to identify the identity of each storage device. After it is determined that the current storage device belongs to a legal storage device, the device information of the current storage device is recorded in the log information, so that when a problem occurs subsequently, the cause can be traced.
[0098] The application scenario of the data storage method for zero terminal peripherals provided by the embodiments of the present disclosure is described below.
[0099] Scenario one:
[0100] After the R end and the S end have established a connection, when the terminal user inserts a peripheral storage device SSD, the R end software detects the new device and sends a notification to the S end. After receiving the notification, the S end starts an automatic detection program, identifies that it is a legal storage device of the company, and records the device information. Subsequently, the S end requests the CA platform to verify the access permission of the terminal user and the data storage level, and determines, through the verification result returned by the CA, that the current terminal user has write permission and the data storage level is the high-performance layer (hot data). After the CA platform returns the permission information and the data storage level of the terminal user, the S end stores the data in the medium-performance layer (warm data) according to the predicted access frequency of the data, because the inserted is a high-performance storage device, the data division is not matched with the medium-performance layer data. Finally, the R end does not write data, and returns a notification message to the user that the current storage device level does not match the data storage level.
[0101] Scenario two:
[0102] After the R end and the S end have established a connection, when the terminal user inserts a peripheral storage device SSD, the R end software detects the new device and sends a notification to the S end. After receiving the notification, the S end starts an automatic detection program, identifies that it is a legal storage device of the company, and records the device information. Subsequently, the S end requests the CA platform to verify the access permission of the terminal user and the data storage level, and determines, through the verification result returned by the CA, that the current terminal user has write permission and the data storage level is the high-performance layer (hot data). After the CA platform returns the permission information and the data storage level of the terminal user, the S end stores the data in the medium-performance layer (warm data) according to the predicted access frequency of the data, because the inserted is a high-performance storage device, the data division is not matched with the medium-performance layer data. Finally, the R end does not write data, and returns a notification message to the user that the current storage device level does not match the data storage level. Specifically, in this example, whether it belongs to a legal device can be determined through a device ID. The device ID is usually a serial number, which is a unique identifier of the storage device and can be used to identify the identity of each storage device. After determining that the current storage device belongs to a legal storage device, the device information of the current storage device is recorded in the log information, so that in the case of subsequent problems, the traceability can be achieved.
[0103] Scenario three:
[0104] After the R end and the S end have established a connection, when the terminal user inserts a peripheral storage device SSD, the R end software detects the new device and sends a notification to the S end. After receiving the notification, the S end starts an automatic detection program, identifies that it is a legal storage device of the company, and records the device information. Subsequently, the S end requests the CA platform to verify the access permission of the terminal user and the data storage level. The information returned by the CA platform indicates that the terminal user has no access permission, and the R end storage device does not display data.
