• If a snapshot's source disk is deleted, all legacy snapshots of this disk are also deleted.
• If you reinstall or change the server OS, snapshots of the system disk are automatically deleted. Those of the data disks can be used as usual.
• A snapshot whose name starts with autobk_snapshot_vbs_, manualbk_snapshot_vbs_, autobk_snapshot_csbs_, or manualbk_snapshot_csbs_ is automatically generated during backup. You can only check details of such snapshots and cannot delete them.
