Roll Back a Disk
Last Updated：2020-07-20
You can roll back the disk content by using the snapshot of specified disk itself.
- This operation can be performed only when the disk is in the Available status:
- The specified snapshot ID (snapshotId) must be a snapshot created through the specified disk ID (volumeId).
- If the system disk is rolled back, this operation can be performed only when the instance is in the Running or Stopped status.
Notes:
If the system disk snapshot is rolled back, the data of system disk since this snapshot is lost completely and can not be recovered.
