Description

Legacy snapshots

  • 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 check details of such snapshots, but cannot delete them.

Standard snapshots

  • Standard snapshots are not deleted even if their source disks are deleted.
  • When you delete a disk whose standard snapshots have Instant Snapshot Restore enabled, the standard snapshots will be not deleted, but Instant Snapshot Restore will be disabled automatically.
  • If you reinstall or change the server OS, standard snapshots will be not deleted, but Instant Snapshot Restore will be disabled automatically if it has been enabled for the standard snapshots of the system disk.

General constraints

  • If a snapshot is deleted, disks rolled back or created from this snapshot are not affected.
