Point in time rollback
You can also restore a snapshot of an entire file system, volume, or share 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, volume, or share to the original location on the client.
Performing rollback using snapshot:
- On the left, click Recovery. In the Recover page, under Regular recovery, click Start recovery.
- In the Basic properties tab, select policy type as NAS-Data-Protection. Select Restore type as Point In Time Rollback. Select the Source client from where you want to recover, and click Next.
- Recovery details tab, the backups are displayed in the Backup History table, select the image for restore. Click Edit to search for the list of snapshot images, for all dates (you cannot set a date range).
- Select an image from the list, and click Next.
Under Restore target options, select Restore everything to original location. You need to specify a NetBackup host.
- (Optional) under Recovery options, select Force rollback even if it deletes the snapshot(s) taken after that backup point. If you do not select this option, recovery does not run, if any snapshots taken after the selected backup point exists.
- If you do not want to use the default media server for recovery, select the required media server. Set a priority for the recovery job.
- In the Review tab, review all the selections that you made. To change any setting, click Previous. Click Start recovery to start the recovery.
