Point in time rollback
You can also restore a snapshot of an entire file system or volume with minimal I/O. This type of restore is called point in time rollback. All the data in the snapshot is restored; single file restore is not available in a rollback.
Warning:
Rollback deletes all files that were created after the creation-date of the snapshot that you restore. Rollback returns a file system or volume to a given point in time. Any data changes or snapshots that were made after that time are lost.
Also, if there are multiple logical volumes on a single disk or volume group and if you perform a Point in Time Rollback of a specific logical volume, the entire disk or volume group is restored to the point in time.
Rollback is available only when you restore the file system or volume to the original location on the client.
Performing rollback using snapshot:
- Start the Backup, Archive, and Restore interface.
- Click the Restore Files tab.
- Click Actions > Specify NetBackup Machines to specify the server, source client, policy type, and destination client.
- For Restore Type, select Point in Time Rollback.
The Browse directory field is grayed out, with root (/) as default.
Instant Recovery backups are displayed in the Backup History window, for all dates (you cannot set a range).
- Select an image from the list, and click OK.
The image contents are displayed in the Directory Structure pane of the Restore Files tab.
- Select a volume for rollback, click Restore.
