A promoting rollback restores a file system that is an object replication target to a live file system.

Review the considerations for a rollback in Rolling back a file system from a snapshot.
  1. Navigate to Data Management > Protection > Snapshots > File System Snapshots.
  2. In the Snapshots pane, select the EVS and file system associated with the snapshot from the list of EVS instances.
  3. Locate the snapshot that you want to roll back to, click the more actions menu, and then click Rollback.
  4. In the Roll Back File System window, select Promote.
  5. Review the file system details: EVS name, file system name, and file system mount status.
  6. Review the details for the latest object replication version: status, source file system, source server, and source file system status.
  7. Review and configure the rollback steps. The steps include automatically unmounting the file system.
    1. In the Recover file system to snapshot created at list, select the snapshot that you want to roll back to.
      The listed snapshots are shown by date and time. The version snapshot name and source file system are shown for the selected snapshot.
    2. In the Remount file system as list, select one of the following options:
      • Mount read write: This option mounts the file system in read/write mode and is the default. If you roll back a file system and mount it in read/write mode, you cannot undo the rollback or roll back again to a different snapshot.
      • Mount read only: This option mounts the file system in read-only mode. If a file system is an object replication target, it must be mounted in read-only mode. You can also mount the file system in read-only mode for other reasons such as to verify the file system status and decide whether to remount the file system in read-write mode or to restore to a different snapshot.
      • Do not mount: This option prevents the file system from mounting. Some features, such as formatting a file system, require that the file system is unmounted. You must also unmount a file system to remove it.
    3. Under Remove access points, select Shares and Exports (the defaults) to exclude SMB shares and NFS exports from the rollback. To include shares or exports, clear the applicable checkbox.
      For information about SMB share access points, see the description of Transfer to Object Replication Target in Additional information about creating an SMB share.

      For information about NFS export access points, see the description of Transfer to Object Replication Target in Additional information about creating an NFS export.

  8. If the object replication target and the promoted file system are on the same EVS, you must select the export that the NFS clients will access. You can choose exports on the source file system (the default) or on the promoted file system.
  9. Click Rollback, and then click Continue to confirm.
