Why Can't I Roll Back My Disk Data from a Snapshot?¶
Possible causes are as follows:
Snapshot data can only be rolled back when the status of the snapshot's source disk is Available or Rollback failed. If the snapshot's source disk is In-use, detach the disk and then use the snapshot to roll back disk data. After the rollback succeeds, re-attach the disk.
Snapshot data can only be rolled back to source EVS disks. Rollback to a different disk is not possible.
If the 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.
