Multi-stream restores from D-NAS backups
Starting with NetBackup version 10.2, you can perform restore of a NAS volume using multiple restore streams. 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 is upgraded to 10.2 to use multi-stream restore.
Each NAS volume restore has a separate parent-child job hierarchy. The parent job is a controller job for the NAS volume and the child job(s) perform the actual restore of the data. Each child restore job represents one restore stream.
