    test steps:
        1. boot VM with one or two data disks
        2. make filesystem in data disks
        3. create file and save it md5sum in data disks
        4. add target disks for backup to VM via qmp commands
        5. do full backup
        6. create new files and save it md5sum in data disks
        7. do incremental backup
        8. destroy VM and rebase incremental backup image
        9. start VM with image in step8
        10. verify files in data disks not change
