How NetApp performs a volume-level rollback restore
NetBackup directs the array or storage device to do a volume-level rollback restore (point-in-time restore) of the snapshot. The device determines how to accomplish the restore.
Several factors affect how the array accomplishes the restore, as follows:
Whether the rollback is from the most recent snapshot or not.
The NetBackup restore option: Force rollback even if it invalidates later snapshots restore.
Whether the mount point from backup selection is a volume or qtree/folder in the volume.
Note:
Using NetApp storage, if a point-in-time rollback restore is performed for one of the volumes in a backup image that consists of multiple volumes, the snapshots corresponding to the remaining volumes will not be immediately deleted from the storage system but they will be immediately removed from the NetBackup catalog. Any subsequent image cleanup job will cause the remaining snapshots to be deleted from the storage system.
Table: Volume-level rollback restore factors describes the interaction between the various factors.
Table: Volume-level rollback restore factors
From the most recent or an older snapshot | restore option | Backup selection mount point* | Description |
|---|---|---|---|
From the most recent snapshot | Either selection | Volume | The device performs a rollback restore of the volume. Because it is a rollback restore, the restore occurs almost immediately. |
From the most recent snapshot | Either selection | Qtree or folder | The device performs a file-level restore of the backup selection mount point* rather than a volume-level rollback restore. Such a restore is much slower than a volume-level rollback restore in which no data moves. |
From an older snapshot | Checked | Volume | The device performs a rollback restore of the volume. Because it is a rollback restore, the restore occurs almost immediately. Because the rollback restore replaces the current volume with the older snapshot, more recent snapshots are lost. |
From an older snapshot | Either selection | Qtree or folder | The device performs a file-level restore of the backup selection mount point* rather than a volume-level rollback restore. Such a restore is much slower than a volume-level rollback restore in which no data moves. Unlike a volume-level rollback restore, this type of restore does not destroy more recent snapshots. |
From an older snapshot | Unchecked | Volume | The restore fails. |
* For NDMP backups the entire backup selection is considered and not just the part that is mounted.
