[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0041] In cloud computing operation and maintenance platforms, data backup is usually required to ensure data security and business continuity. However, traditional manual backup or scheduled incremental backup is not only inefficient, but also easily interrupts business processes and cannot meet the business continuity requirements of cloud computing operation and maintenance platforms, resulting in the inability to advance business processes on cloud computing operation and maintenance platforms normally, reducing the reliability of cloud computing operation and maintenance platforms.

[0042] Based on this, an embodiment of the present invention provides a data backup method, which obtains historical load information corresponding to each time period, and determines an idle time period set based on the historical load information corresponding to each time period and the preset load value; groups the target data based on the data priority to obtain multiple groups of data to be backed up; the multiple groups of data to be backed up correspond to different data priorities; if the data volume of the data to be backed up reaches the preset threshold, the backup time period is determined from the idle time period set; and the data to be backed up is backed up during the backup time period. In this way, the idle time period set is determined based on the historical load information and the preset load value corresponding to each time period, and the backup time period is determined from the idle time period set when the data volume of the data to be backed up reaches the preset threshold, and the data to be backed up is backed up during the backup time period, thereby performing data backup during the idle time period, improving the efficiency of data backup, and at the same time reducing the impact on the business process of the cloud computing operation and maintenance platform, and improving the reliability of the cloud computing operation and maintenance platform.

[0043] According to an embodiment of the present invention, a data backup method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0044] In this embodiment, a receipt backup method is provided, which can be used in the above-mentioned cloud computing operation and maintenance platform. Figure 1 is a flow chart of a data backup method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0045] Step S101, obtaining historical load information corresponding to each time period, and determining an idle time period set based on the historical load information corresponding to each time period and a preset load value.

[0046] In an embodiment of the present invention, historical load information corresponding to each time period in a statistical period is obtained. Among them, any duration such as a day, a week, and a business process processing cycle can be used as a statistical period. A statistical period is divided into multiple time periods, and the duration of each time period is the unit statistical duration, such as one hour. The historical load information is the load information corresponding to each time period in one or more past statistical periods. The load information is used to measure the data processing volume or load utilization of the cloud computing operation and maintenance platform in the corresponding time period; the load information may include information such as CPU load utilization, memory utilization, and platform access volume.

[0047] In the embodiment of the present invention, the preset load value is used to define the load threshold corresponding to the idle period. Each of the multiple information included in the load information has a corresponding preset load value; only when all the information in the load information meets the limit of the preset load value can a period be determined as an idle period.

[0048] In the embodiment of the present invention, the determined multiple idle time periods are collected to obtain an idle time period set.

[0049] Step S102: grouping the target data based on the data priority to obtain multiple groups of data to be backed up.

[0050] In the embodiment of the present invention, the target data is the data that needs to be backed up in the cloud computing operation and maintenance platform; the multiple groups of data to be backed up correspond to different data priorities. For different data types, the data priorities are also different; according to the data priority, the target data is grouped, and the target data with the same data priority is grouped into one group, so as to obtain multiple groups of data to be backed up.

[0051] In an optional implementation, each data type corresponds to a different data priority, and among the multiple groups of data to be backed up obtained by grouping, each group of data to be backed up corresponds to a different data type, thereby achieving refined grouping. When backing up data, it can be backed up separately according to the data type.

[0052] In an optional implementation, different data types may correspond to the same data priority, and each of the multiple groups of data to be backed up obtained by grouping may contain data of multiple data types, thereby backing up data of multiple data types simultaneously.

[0053] In an optional implementation, data priority can be determined according to the data importance of different data types. The data importance is judged based on the impact of each data type on the operation of the cloud computing operation and maintenance platform, the difficulty of data regeneration, etc., so as to determine the data priority corresponding to each data type.

[0054] Step S103: if the amount of data to be backed up reaches a preset threshold, a backup period is determined from the idle period set.

[0055] In the embodiment of the present invention, if the amount of data to be backed up reaches a preset threshold, the backup of the data to be backed up can be started at this time, and an idle period that can meet the backup requirements of the data to be backed up is determined from the idle period set and is determined as the backup period. Among them, meeting the requirements of the data to be backed up means that the backup of the data to be backed up can be completed within the period.

[0056] In an optional implementation, the modified data is recorded in the log from the last backup to the current time, and the data volume is calculated, so as to obtain the data volume of each group of data to be backed up.

[0057] In an optional embodiment, if there are multiple groups of data to be backed up, whether the data volume of the data to be backed up with the highest data priority reaches a preset threshold is used as a criterion for determining whether to start the backup of the data to be backed up; at the same time, if the data volume of the data to be backed up with the highest data priority reaches the preset threshold, it is determined whether the data volume of the data to be backed up with other data priorities reaches the preset threshold, and the backup of the other data to be backed up whose data volume reaches the preset threshold is started.

[0058] Step S104: backing up the data to be backed up within the backup period.

[0059] In the embodiment of the present invention, after the backup period is determined, when the backup period is reached, the data to be backed up is backed up, so that the business process of the cloud computing operation and maintenance platform is not affected while the data backup is completed.

[0060] The data backup method provided by the embodiment of the present invention obtains the historical load information corresponding to each time period, and determines the idle time period set based on the historical load information corresponding to each time period and the preset load value; groups the target data based on the data priority to obtain multiple groups of data to be backed up; the multiple groups of data to be backed up correspond to different data priorities; if the data volume of the data to be backed up reaches the preset threshold, the backup time period is determined from the idle time period set; and the data to be backed up is backed up within the backup time period. In this way, the idle time period set is determined based on the historical load information and the preset load value corresponding to each time period, and the backup time period is determined from the idle time period set when the data volume of the data to be backed up reaches the preset threshold, and the data to be backed up is backed up within the backup time period, so that data backup is performed in the idle time period, the efficiency of data backup is improved, and at the same time, the impact on the business process of the cloud computing operation and maintenance platform is reduced, and the reliability of the cloud computing operation and maintenance platform is improved.

[0061] In this embodiment, a receipt backup method is provided, which can be used in the above-mentioned cloud computing operation and maintenance platform. Figure 2 is a flow chart of another data backup method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0062] Step S201, obtaining historical load information corresponding to each time period, and determining an idle time period set based on the historical load information corresponding to each time period and a preset load value.

[0063] Specifically, step S201 includes:

[0064] Step S2011, determining a time period in which the corresponding historical load information is less than a preset load value as an idle time period.

[0065] In the embodiment of the present invention, the period when the corresponding historical load information is less than the preset load value is determined as the idle period. If the historical load information contains multiple information, when each information is less than the corresponding preset load value, the period is determined as the idle period.

[0066] Step S2012, summarize and aggregate the idle time periods to obtain an idle time period set.

[0067] In the embodiment of the present invention, the idle time periods obtained are summarized, and the idle time periods that are continuous in time are aggregated to obtain a complete idle time period, and the aggregated idle time periods are summarized to obtain an idle time period set. For example, the idle time periods obtained in step S2011 are T1, T2, and T3, where T1 and T2 are continuous in time, and T1 and T2 are aggregated into a new idle time period T, and the start time corresponding to the new idle time period T is the start time of T1, and the end time is the end time of T2, and the idle time period set obtained thereby includes two idle time periods, namely T and T3.

[0068] In an optional implementation, in order to avoid the preset load value from placing too strict restrictions on the idle period, resulting in the idle period being too short and unable to meet the backup requirements, the duration required for a full backup of data within a statistical period is calculated, and a minimum backup duration is determined based on the duration and a preset ratio. If the maximum duration of the idle period in the obtained idle period set is less than the shortest backup duration, it indicates that the duration of the idle period in the obtained idle period set is too short. Therefore, the preset load value is readjusted, the threshold corresponding to the preset load value is increased, and the idle period set is redetermined based on this.

[0069] Step S202: group the target data based on the data priority to obtain multiple groups of data to be backed up. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0070] Step S203: If the amount of data to be backed up reaches a preset threshold, a backup period is determined from the idle period set. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0071] Step S204: Back up the data to be backed up during the backup period. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0072] In this embodiment, a receipt backup method is provided, which can be used in the above-mentioned cloud computing operation and maintenance platform. Figure 3 is a flow chart of another data backup method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0073] Step S301, obtain the historical load information corresponding to each time period, and determine the idle time period set based on the historical load information corresponding to each time period and the preset load value. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0074] Step S302: group the target data based on the data priority to obtain multiple groups of data to be backed up. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0075] Step S303: if the amount of data to be backed up reaches a preset threshold, a backup period is determined from the idle period set.

[0076] Specifically, step S303 includes:

[0077] Step S3031: Determine a target backup duration corresponding to the data to be backed up based on the amount of data to be backed up.

[0078] In the embodiment of the present invention, the backup time required to back up the data to be backed up is calculated based on the data volume of the data to be backed up and the speed of backing up the data, so as to obtain the target backup duration corresponding to the data to be backed up.

[0079] In an optional implementation, if there are multiple groups of data to be backed up whose data volume reaches a preset threshold, the backup durations of the multiple groups of data to be backed up are determined separately based on the data volume of the multiple groups of data to be backed up; then, the backup duration with the shortest duration among the multiple backup durations is determined as the target backup duration.

[0080] Step S3032: determine the idle time periods in the idle time period set whose duration is longer than the target backup duration as backup time periods.

[0081] In the embodiment of the present invention, in order to ensure that data backup can be completed within an idle period, an idle period in the idle period set whose duration is greater than the target backup duration is determined as a backup period.

[0082] In an optional implementation, if there is no idle period in the idle period set whose duration is greater than the target backup duration, in order to ensure that data backup can proceed normally, the data to be backed up is divided into multiple data blocks to be backed up based on a preset data volume; then, the idle period in the idle period set whose duration is greater than the backup duration corresponding to the preset data volume is determined as the backup period.

[0083] In an optional implementation, the data to be backed up may be split according to the data type in the data to be backed up to obtain multiple data blocks, and the backup period may be determined according to the data volume of the obtained data blocks. If the backup period cannot be obtained after splitting according to the data type, each data block may be split again according to the preset data volume to obtain the backup period.

[0084] In an optional implementation, the preset data volume may be a preset size of a data block. When all data backup cannot be completed within an idle period, the data to be backed up is divided into multiple data blocks to be backed up according to the preset data volume.

[0085] In an optional implementation, the data to be backed up may be divided into a plurality of data blocks to be backed up with equal data volumes according to the current data volume of the data to be backed up, for example, divided into two data blocks to be backed up with equal data volumes, and the target backup duration corresponding to the split data blocks to be backed up is compared with the duration of the idle time period in the idle time period set to determine the backup time period. If there is still no idle time period that meets the backup requirements after one split, splitting is performed again until a backup time period is determined from the idle time period set.

[0086] In an optional implementation, the backup data volume that can be satisfied by the shortest idle period in the idle period set can also be used as the preset data volume, and the data to be backed up can be divided into multiple data blocks to be backed up. Specifically, the idle period with the shortest duration, the speed of backing up data, and the duration of the idle period are determined from the idle period set, and the backup data volume that can be satisfied by the idle period is determined, and the backup data volume is used as the preset data volume. In this case, all idle periods in the idle period set can be used as backup periods.

[0087] In an optional implementation, the amount of backup data that can be satisfied by the idle periods in the idle period set can be taken as the preset data amount in sequence, and the data to be backed up can be split in sequence to obtain data blocks to be backed up, so that data backup can be performed in each idle period in the idle period set.

[0088] Step S304: Back up the data to be backed up during the backup period. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0089] In this embodiment, a receipt backup method is provided, which can be used in the above-mentioned cloud computing operation and maintenance platform. Figure 4 FIG. 1 is a flow chart of another data backup method according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0090] Step S401, obtain the historical load information corresponding to each time period, and determine the idle time period set based on the historical load information corresponding to each time period and the preset load value. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0091] Step S402: group the target data based on the data priority to obtain multiple groups of data to be backed up. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0092] Step S403: If the amount of data to be backed up reaches a preset threshold, a backup period is determined from the idle period set. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0093] Step S404: backing up the data to be backed up within the backup period.

[0094] Specifically, step S404 includes:

[0095] Step S4041, when the backup period starts, obtain the current load information corresponding to the backup period.

[0096] In the embodiment of the present invention, when the backup period starts, that is, when the current time reaches the start time of the backup period, the load information at the current time is acquired to obtain the current load information corresponding to the backup period.

[0097] Step S4042: if the current load information corresponding to the backup period is less than the preset load value, the data to be backed up is backed up.

[0098] In the embodiment of the present invention, if the current load information corresponding to the backup period is less than the preset load value, it indicates that the cloud computing operation and maintenance platform is in an idle state or the current business process occupies a low load and memory, and the current data backup will not affect the normal business process, so the backup data is backed up at this time. Repeat the above steps until all the backup data are backed up, thereby completing the data backup.
