A person of ordinary skill in the art will appreciate that with the evolution of tape library backup and archiving devices and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is equally applicable to similar technical problems.

[0096] This application backs up changed files to tapes according to the incremental backup strategy, and archives the backup data to tapes according to the archiving strategy, thereby improving backup efficiency, optimizing storage management, and improving data management efficiency.

[0097] In this embodiment, the method for backing up and archiving a tape library is described from the perspective of the method. The method for backing up and archiving a tape library can be integrated into the tape library backing up and archiving system 100 .

[0098] The present application provides a tape library backup and archiving method, which includes: obtaining a tape loading instruction, loading a target tape into a tape drive; rewinding the target tape to the starting position of the target tape; obtaining a positioning instruction, and positioning the target tape to the target position through the positioning instruction; traversing each file in the backed-up data in the target tape, comparing the data to be backed up with the backed-up data, and obtaining target incremental data, wherein the target incremental data includes newly added files, modified files, and deleted files; obtaining a tape backup instruction, and backing up the target incremental data to the target position of the target tape through the tape backup instruction.

[0099] See also Figure 2 , Figure 2 This is a flow chart of an embodiment of a tape library backup and archiving method in an embodiment of the present application. The tape library backup and archiving method includes the following steps 201 to 205:

[0100] 201. Obtain a tape loading instruction and load a target tape into a tape drive.

[0101] Specifically, the tape loading instruction is an instruction for loading the tape where the data to be backed up is stored into the drive when data backup is required. It is an instruction triggered when data backup is required. Optionally, when the tape library backup and archiving method is applied to the tape backup and archiving system, the tape loading instruction can be triggered by the "backup" label on the user terminal interface. Optionally, there can be multiple instructions triggered by the "backup" label, including tape loading instructions, positioning instructions, and tape backup instructions. The specific trigger label can have other forms, which are only used as examples and are not limited here. Optionally, the tape library usually includes multiple tape drives and an automatic loading mechanism. Optionally, after the user terminal triggers the tape loading instruction by clicking the corresponding label or other means, according to the data such as the tape serial number contained in the tape loading instruction, the automatic loading mechanism of the tape library is used to load the target tape with the tape serial number that matches the tape serial number into the tape drive.

[0102] 202. Rewind the target tape to the starting position of the target tape.

[0103] Specifically, after the target tape with the matching tape serial number is loaded into the tape drive by the automatic loading mechanism, the tape is rewound to the starting position before the backup task is executed, and the target position of the tape is located according to the target position identifier of the target tape included in the positioning instruction.

[0104] 203. Obtain a positioning instruction, and locate the target position of the target magnetic tape according to the positioning instruction.

[0105] Specifically, the positioning instruction includes an identifier of the target position of the target tape. For example, the position of the target position n files after the starting position is obtained through the positioning instruction. Then, the positioning instruction can be used to skip n files at the starting position of the target tape and then locate the target position of the target tape. Specifically, the target position of the target tape is the location of the backup data. Optionally, when the tape library backup and archiving method is applied to the tape library backup and archiving system, the user can view the usage status of each tape in the tape library on the user terminal. The usage status includes "writing", "to be written", "full" and "unused", etc. Optionally, the user can select a tape with a status of "unused" as the target tape, triggering the corresponding "backup" label, thereby triggering the tape loading instruction and the corresponding positioning instruction, which is convenient for the subsequent execution of the backup task.

[0106] 204. Traverse each file in the backed-up data in the target tape, compare the data to be backed up with the backed-up data, and obtain target incremental data.

[0107] Optionally, the target incremental data includes newly added files, modified files, and deleted files. Specifically, the data backup process involves multiple backup methods, including full backup, incremental backup, and differential backup. Specifically, full backup refers to the complete backup of data. For example, one tape is used to back up the entire business system on Monday, and another tape is used to back up the entire business system on Tuesday, and so on. Full backup will cause a large amount of duplicate backup data, and the duplicate data will occupy a large amount of tape space, which means increased costs. When the amount of backup data is large, the time required for backup will also be longer. Specifically, incremental backup is a backup method based on the last backup, that is, only the newly added or modified data is backed up every day. For example, a full backup is performed on Monday, and the data added between Monday and Tuesday is backed up on Tuesday, and the data added between Tuesday and Wednesday is backed up on Wednesday, and so on. The advantage of the incremental backup strategy is that only the data updated or added on the day is backed up. Because the amount of data is small, tape space is saved and the backup time is shortened. However, the disadvantage is that the data recovery process is more cumbersome. For example: on Friday, the system fails and data is lost. The data needs to be restored to the state on Thursday. The user must first find Monday's full backup to restore, then find Tuesday's backup to restore Tuesday's data, and then find Wednesday's backup to restore Wednesday's data, until Thursday's data is restored. This type of backup has poor reliability. Once an error occurs in a backup, the data of the entire system will be incorrect. Specifically, differential backup is another backup method based on full backup. For example: a full backup is performed on Monday, and data added (deleted or modified) between Monday and Tuesday is backed up on Tuesday. Data added (deleted or modified) between Monday and Wednesday is backed up on Wednesday, and so on. Differential backup does not require a full backup of the system every day, and is also simpler and more convenient during the recovery process. Only the full backup and the data backed up on that day are needed to restore the data of a certain day.

[0108] Optionally, the tape library backup archiving method can adopt any one of the above backup strategies or a combination of the three backup strategies. Taking incremental backup as an example, after obtaining the data to be backed up, traverse each file in the backed up data in the target tape, compare the data to be backed up with the backed up data to obtain the target incremental data, so as to subsequently back up the target incremental data. Optionally, the backed up data can be the data stored in a backup before this backup.

[0109] 205. Obtain a tape backup instruction, and back up the target incremental data to a target position of the target tape using the tape backup instruction.

[0110] Specifically, the tape backup instruction can also be triggered through the "backup" label on the user terminal interface. After obtaining the target incremental data, the tape backup instruction is obtained, and the target incremental data is backed up to the target location of the target tape through the tape backup instruction. Optionally, after the backup is completed, the target tape is unloaded from the automatic loading mechanism and returned to the specified slot by obtaining the tape unloading instruction.

[0111] The embodiment of the present application backs up the changed files to the tape according to the incremental backup strategy, and archives the backup data to the tape according to the archiving strategy, thereby improving the backup efficiency, optimizing the storage management, and improving the data management efficiency.

[0112] In one embodiment of the present application, the obtaining of the tape backup instruction, backing up the target incremental data to the target location of the tape by the tape backup instruction, includes:

[0113] All files in the target incremental data are written into a magnetic tape, and metadata indexes of newly added files and modified files in the target incremental data are updated; and metadata indexes of deleted files in the target incremental data are marked.

[0114] Specifically, the target incremental data includes newly added files, modified files, and deleted files. Incremental backup requires comparison of newly added, modified, and deleted files in the data to be backed up and the full backup data. Optionally, in order to realize the backup of the target incremental data to the target location of the tape, a full backup, i.e., a full backup, can be performed in a preset time period, and all files in all data can be written to the tape and numbered. During the writing process, a metadata index is generated, and the metadata of each file is recorded. Optionally, the metadata of the file can include the file name, size, modification time, etc., as well as the location in the tape. The backup file stored in the tape can be quickly found through the metadata index. The metadata index and the metadata are stored in the tape together, so that the incremental data can be backed up later. Optionally, the storage format of the metadata index can be in the form of a simple key-value pair, such as a hash table or a database format. For each metadata, its unique identifier is recorded, which can be a file path or a hash value. The metadata index and the metadata are stored in the tape to ensure that the unique identifier, size, modification time, and location in the tape of each metadata are stored in the tape.

[0115] Optionally, when performing an incremental backup, the current tape library system status is compared with the status at the time of the last backup through a traversal operation, and new files, modified files, and deleted files are determined through traversal search and comparison. For example: when the tapes used for the last file backup are numbered 1-100, new files and modified files are obtained after traversal, and the new files and modified files are written to tapes numbered 101-150. Optionally, the metadata index of new files and modified files is updated at the same time. For deleted files in the target incremental data, the location of the deleted files is found according to the metadata index, and the status of the deleted files is marked as deleted, so as to facilitate cleanup operations during subsequent backups.

[0116] The embodiment of the present application determines the newly added files, modified files and deleted files in the target incremental data through traversal comparison, and backs up the incremental data to the target location of the tape to update the backup data.

[0117] In one embodiment of the present application, the method further includes:

[0118] Obtain a tape recovery instruction, obtain a target recovery data sequence through the tape recovery instruction, determine the target tape according to the target recovery data sequence, wherein the target tape stores the target recovery data; load the target tape into the tape drive; rewind the target tape to the starting position of the target tape; locate the target recovery data at a target position on the target tape according to the tape recovery instruction; and restore the target recovery data from the target position to a specified directory.

[0119] Specifically, after the backup is completed, when the file system needs a part of the backup data, the data must be restored. Optionally, when the tape library backup archiving method is applied to the tape backup archiving system, the tape recovery instruction can be triggered through the "Restore" label on the user terminal interface. Optionally, the tape recovery instruction includes a target recovery data sequence. After obtaining the tape recovery instruction, the target recovery data sequence can be obtained, and the target tape is determined according to the target recovery data sequence. The target tape stores the target recovery data. Similarly, the target recovery data sequence can be used to know the location of the target recovery data n files after the starting position of the tape, and the recovery instruction can be used to locate the location. After skipping n files at the starting position of the target tape, the target location of the target recovery data is located, thereby restoring the target recovery data from the target location to the specified directory. Specifically, the tape recovery instruction can include a specified directory for tape recovery. When the tape recovery instruction is obtained, the specified directory can be obtained, thereby restoring the target recovery data to the instruction directory. Optionally, in the tape backup and archiving system, the user interface has a specified directory input item and a target recovery data serial number selection item. Through the user's input, the tape library backup and archiving system can obtain the target recovery data serial number and the specified directory input by the user.
