Restoring (rolling back) from an array-based snapshot
The following procedure describes how to perform a volume-level rollback restore (point-in-time restore) from a snapshot that NetBackup Replication Director manages. The storage device replaces the protected volume with the snapshot of the volume.
NetBackup supports point-in-time rollback restores for only NAS devices and only for copy one. Point-in-time rollback restores are not supported for SAN devices on Windows or UNIX.
Note:
Do not perform a point-in-time rollback restore on a volume which is shared across multiple policies because it retains the stale catalog entries for another policy or policies.
See How NetApp performs a volume-level rollback restore.
To restore from an array-based snapshot
- Begin the restore procedure as follows:
Windows
Click File > Select Files and Folders to Restore > from Point in Time Rollback.
The NetBackup History pane shows the available snapshots from which you can restore.
UNIX
Click the Restore Files tab, then select Point in Time Rollback for the Restore Type.
The Date Range dialog box appears.
The following is an example of the restore window on a Windows computer:
- Select a snapshot as follows:
Windows
In the NetBackup History pane, select the snapshot to restore.
The snapshot appears in the All Folders pane.
UNIX
In the Date Range dialog box, select a snapshot from the list and click OK.
The snapshot contents appear in the Directory Structure pane.
- Select the volume, as follows:
Windows
In the All Folders pane, expand the directory tree to find the volume mount point (if necessary) and then click the check box next to the mount point for the volume.
UNIX
In the Directory Structure pane, expand the directory tree to find the volume mount point (if necessary) and then click the check box next to the mount point for the volume.
- Begin the restore, as follows:
Windows
Click Actions > Restore....
UNIX
Click Restore.
The Restore Marked Files dialog box appears.
Most options are selected by default and cannot be changed.
The following is an example of the Restore Marked Files dialog box on a Microsoft Windows computer:
- In the Restore Marked Files dialog box, select from the following options to meet the requirements for the restore:
Restore Options
Skip verification and force rollback
By default, NetBackup performs several checks on the file system during the restore. If the checks fail, the restore stops. Select this option to skip verification.
Warning:
Select this option only if you are sure that you want to replace all of the files in the original location with the snapshot. Rollback deletes all files that were created after the creation-date of the snapshot from which you restore.
Force rollback even if it invalidates later snapshots
This option applies only if you restore from a snapshot other than the most recent one.
Warning:
Select this option only if you are sure that you want to replace the original volume with the snapshot. If more recent snapshots that have been replicated exist and you do not select this option, the rollback restore fails.
Job Priority
To change the priority of this restore, click Override default priority and then set a priority number.
The default is 90000. The available range is 0 to 99999.
- Click Start Restore.
- In the dialog box that appears, click Yes to view the restore status.
If file verification fails, a message appears in the View Status dialog box (Windows) or Task Progress tab (UNIX) that indicates the restore was not performed.
After a restore operation begins, you can close Backup, Archive, and Restore to perform other tasks on your computer. NetBackup continues the restore operation in the background.
