Rolling Back a Snapshot to an EVS Disk (Deprecated)

Function

This API is used to roll back a snapshot to an EVS disk.

Note: This API has been deprecated. Use another API.

Constraints

  • A snapshot can be rolled back only to its source disk. Rollback to another disk is not possible.

  • You can roll back a disk from a snapshot only when the disk is in the available or error_rollbacking state.

  • Snapshots whose names started with the autobk_snapshot_ prefix are automatically created by the system when backups are created. Such snapshots cannot be used to roll back data.
