Hi, Does drive_mirror support incremental backup a running vm? Or other mechanism does? incremental backup a running vm requirements: First time backup, all of the allocated data will be mirrored to destination, then a copied bitmap will be saved to a file, then the bitmap file will log dirty for the changed data. Next time backup, only the dirty data will be mirrored to destination. Even the VM shutdown and start after several days, the bitmap will be loaded while starting vm. Any ideas?
