After generating a plurality of incremental backup files, the embodiment obtains file attribute information of each incremental backup file in the plurality of incremental backup files, and then synchronizes the plurality of incremental backup files to the target virtual machine based on the file attribute information, so that incremental data in the source virtual machine are synchronized to the target virtual machine, and when the source virtual machine fails, the target virtual machine can be used for replacing the source virtual machine to provide services to the outside.

As shown in fig. 3, in order to implement file data merging, in this embodiment, a plurality of temporary merging areas are also pre-constructed, where the plurality of temporary merging areas respectively correspond to the plurality of second virtualized disks.

Specifically, when synchronizing multiple incremental backup files to a target virtual machine based on file attribute information, the embodiment first obtains an accommodating data type and an accommodating data amount of each second virtual disk in multiple second virtual disks, then determines a second virtual disk corresponding to each incremental backup file from the multiple second virtual disks based on the file attribute information, the accommodating data type and the accommodating data amount, then sends each incremental backup file to a temporary merging area of the second virtual disk corresponding to each incremental backup file for merging, obtains a first merging file corresponding to each second virtual disk, and finally synchronizes the first merging file corresponding to each second virtual disk.

In a specific implementation manner, when determining the second virtual disk corresponding to each incremental backup file, the file attribute information includes a file type, a file keyword, a file data amount, a file privacy level, and a file importance level, first, second, third, and fourth file scores of each incremental backup file may be determined based on the file type, the file keyword, the file privacy level, and the file importance level, then, a target file score of each incremental backup file is determined based on the first, second, third, and fourth file scores, and finally, the second virtual disk corresponding to each incremental backup file is determined from the plurality of second virtual disks based on the target file score, the file data amount, the accommodation data type, and the accommodation data amount. For example, the target file scores of the incremental backup files a are respectively 0.85, the second virtual disk a and the second virtual disk B can accommodate the incremental backup files with the target file scores between 0.8 and 0.9, but the accommodating data volume of the second virtual disk B is smaller than the data volume of the incremental backup files a, and the second virtual disk a is determined to be the second virtual disk corresponding to the incremental backup files a.

Further, before determining the first file score, the second file score, the third file score and the fourth file score of each incremental backup file, a corresponding relationship between the file type and the first file score, a corresponding relationship between the file keyword and the second file score, a corresponding relationship between the file privacy level and the third file score, and a corresponding relationship between the file importance level and the fourth file score may be preset, for example, the privacy level a, the privacy level B, and the privacy level C respectively correspond to the third file score A1, the third file score A2, the third file score A3, and the importance level B1, the importance level B2, and the importance level B3 respectively correspond to the fourth file score A4, the fourth file score A5, and the fourth file score A6. After the file type, the file keyword, the file privacy level and the file importance level are obtained, the first file score, the second file score, the third file score and the fourth file score of each incremental backup file can be determined based on the file type, the file keyword, the file privacy level, the file importance level and the preset corresponding relation.

When determining the target file score based on the first file score, the second file score, the third file score and the fourth file score, the first file score, the second file score, the third file score and the fourth file score may be summed, or the first file score, the second file score, the third file score and the fourth file score may be weighted and summed, or the first file score, the second file score, the third file score and the fourth file score may be averaged after summing, which is not limited in the present application.

In one embodiment, the initializing the target virtual machine in step S400 includes:

s410, copying the data blocks in the first virtual disk to a storage pool to generate a plurality of full backup files corresponding to the first virtual disk;

s420, determining a second virtual disk corresponding to each full-volume backup file from a plurality of second virtual disks based on the file attribute information, the accommodating data type and the accommodating data volume of each full-volume backup file;

s430, sending each full-volume backup file to a temporary merging area of a second virtual disk corresponding to each full-volume backup file for merging to obtain a second merging file corresponding to each second virtual disk;

s440, synchronizing the second combined file corresponding to each second virtual disk.

When the target virtual machine is virtualized, the data blocks in the first virtual disk are copied to the storage pool to generate a plurality of full-volume backup files corresponding to the first virtual disk, then the second virtual disk corresponding to each full-volume backup file is determined from the plurality of second virtual disks based on the file attribute information, the accommodating data type and the accommodating data volume of each full-volume backup file, then each full-volume backup file is sent to the temporary merging area of the second virtual disk corresponding to each full-volume backup file to be merged, a second merging file corresponding to each second virtual disk is obtained, and finally the second merging file corresponding to each second virtual disk is synchronized to each second virtual disk. The step of determining the second virtual disk corresponding to each full-backed up file from the plurality of second virtual disks based on the file attribute information, the accommodated data type and the accommodated data amount of each full-backed up file is the same as the step of S620, and the step of S620 may be referred to specifically, and the application is not repeated herein.
