Create snapshots and backups
A snapshot is a point-in-time copy of a disk. A backup is a named copy you keep. Both have a tab on the instance.
Snapshots
On the Snapshots tab, select New Snapshot, pick the disk, and finish.
To restore one, open its action menu and select Restore.
Restoring a snapshot
Data written after the snapshot is lost, the instance's other snapshots become invalid, and an online instance restarts.
Backups
On the Backups tab, select New Backup, pick the disk, name it, and finish.
To restore, open the backup's action menu, select Restore, and choose the target instance and disk.
Restoring a backup
The selected disk is erased and replaced with the backup.
