Rolling Back to a Snapshot (BUI)

Use the following procedure to roll back, or restore, a filesystem or LUN to an existing snapshot.

When a rollback occurs, any newer snapshots (and clones of newer snapshots) are destroyed, and the active data are reverted to the state when the snapshot was taken. Snapshots only include data, not properties, so any property settings changed since the snapshot was taken will remain. Changes to filesystem root directory access are lost during rollback.

The rollback is not allowed if the rollback would remove recent snapshots with a snapshot retention hold.

Note:

When the file retention feature, which is different from the snapshot retention feature, is used with snapshot rollback, certain restrictions can apply. Rollback can be performed on a filesystem with the privileged file retention policy, even when unexpired retained files exist. Filesystems with the mandatory file retention policy can never be rolled back, even when all retained files have expired. For more information, see File Retention Management.

Caution:

This procedure cannot be undone.

1. Go to the share or project that contains the snapshot you want to restore.

   • To restore a filesystem snapshot: From the Shares menu, select Shares.

   • To restore a LUN snapshot: From the Shares menu, select Shares, then LUNs.

2. Hover over the share that contains the snapshot you want to restore, and click the edit icon .
3. Click the Snapshots tab.
4. Hover over the snapshot you want to restore, click its rollback icon and confirm your action.
