Rolling Back Disk Data from a Snapshot

Scenarios

Notes and Constraints

• Snapshot data can only be rolled back to source EVS disks. Rollback to a different disk is not possible.
• You can only roll back disk data from a snapshot when the source disk status is Available (not attached to any server) or Rollback failed. If the source disk is attached, detach the disk first.
• If a snapshot is being created, it cannot be used to roll back disk data.
• A snapshot whose name starts with autobk_snapshot_vbs_, manualbk_snapshot_vbs_, autobk_snapshot_csbs_, or manualbk_snapshot_csbs_ is automatically generated during backup. Such a snapshot can only be viewed. It cannot be used to roll back the disk data.
