Reverting a LUN

Reverting restores a shared folder or LUN to the state at which the snapshot was taken. Restoring data using snapshot revert is faster than restoring individual files and folders.

  1. Go to Storage & Snapshots > Storage > Storage/Snapshots.
  2. Select a block-based LUN.

    The LUN must have at least one snapshot.

  3. Click Snapshot, and then select Snapshot Manager.

    The Snapshot Manager window opens.

  4. Select a snapshot.
  5. Click Revert LUN Snapshot.

    All changes made after the snapshot was taken will be deleted.

  6. Optional: Unlock the LUN.

    If the snapshot source is an encrypted LUN, you must provide the encryption password or encryption key file. When the encrypted LUN is restored, it will be unlocked.

    1. Enter the encryption password or upload the encryption key file.
    2. Optional: Select Auto unlock on startup.

      This setting allows the system to automatically unlock the restored LUN every time the NAS starts, without requiring the user to provide the encryption password or encryption key file.

      You can change this setting at any time. For details, see Managing LUN Encryption.

  7. Optional: Configure the following settings.



    Re-map LUN to the same iSCSI target after revert

    If enabled, QuTS hero automatically remaps the LUN to its current target after reverting. If disabled, you must manually remap the LUN after reverting.

  8. Click Local Revert.

QuTS hero unmaps the LUN from its iSCSI target. The status of the LUN changes to Reverting.
