Multi-stream restores from D-NAS backups

Starting with NetBackup version 10.2, you can restore a NAS volume using multiple restore streams from NetBackup-created backup images. Each restore stream runs in parallel, and the restored files are dynamically distributed to each of these restore streams. This helps in achieving optimal performance during restore job. The result is a faster NAS volume restores. Ensure that the primary and media servers, along with the NetBackup client are upgraded to 10.2 to use multi-stream restore.

NetBackup version 10.5 onwards supports multi-stream restore from NetBackup-created backup images, snapshots, and replica copies.

Each NAS volume restore has a separate parent-child job hierarchy. The parent job is a controller job for the NAS volume and one or more child jobs perform the actual restore of the data. Each child restore job represents one restore stream.
