Can a Server Be Restored from Its Backups After It Is Changed?

Yes. If a server has been backed up and later modified (for example, by adding, deleting, or expanding disks), its existing backups can still be used to restore data. However, it is recommended that you perform another backup after making such changes.

If you add a disk after a backup, restoring data from that backup will not restore any data stored on the newly added disk.

If you delete a disk after a backup and then restore data from that backup, the data on the deleted disk will not be restored.

If you have changed the server OS after a backup and then use a system disk backup to restore the original system disk, the system disk data cannot be restored because the disk UUID has changed. If the entire server is backed up and you changed the server OS, the backup can be used to restore data only after you have changed back to the original OS or reinstalled the original system on the source server.
