Why Can't I Roll Back My Disk Data from a Snapshot?

Possible causes are as follows:

• Snapshot data can be rolled back only when the status of the snapshot's source disk is Available or Rollback failed. If the snapshot's source disk is in the In-use state, detach the disk first and then roll back the snapshot data. After the rollback succeeds, re-attach the disk.
• 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.
