Can I Roll Back Data from a Snapshot After Reinstalling the OS or Formatting a Disk?
- If you have reinstalled or changed the server OS: Snapshots of the system disk are automatically deleted. Snapshots of the data disks can be used as usual.
- If you have formatted a disk, snapshots can still be used to roll back the disk data.
