Considerations for restoring from D-NAS backups
You can use the NetBackup web UI to restore individual files or directories, or a volume.
Points to remember before restoring:
NAS-Data-Protection policy does not support original location restore.
The destination client for the restoration must be a NetBackup host. For example, a media server or backup host.
If you select either of the following rename options, ensure that you change the destination path:
Rename hard links.
Rename soft links.
NetBackup version 10.5 onwards supports multi-stream restore from NetBackup-created backup images, snapshots, and replica copies. To use the multi-stream restore feature, upgrade the primary, media, mount host, and restore destination clients to version 10.5 onwards.
To use the multi-stream restore feature for backup copies, all the images selected in the selected time interval must be backup copies and set as primary copies.
Similarly, to use the multi-stream restore feature from the snapshot or replica copies, all the images selected in the selected time interval must be snapshot or replica copies and set as primary copies.
NetBackup version 10.5 onwards supports checkpoint restarts for single and multi-stream restores.
The checkpoint restore is supported for the backup copy only. It is not supported for restoring from snapshots or replica copies.
NetBackup automatically maintains the checkpoint interval intervals.
For a NAS volume, if there are multiple copies of NetBackup-created backup images, then NetBackup restores data from the first non-snapshot or non-replica copy. To restore from a specific backup copy, set that copy as the primary copy in the NetBackup catalog.
