Dynamic streaming parameter
Dynamic streaming is a group of backup streams running in parallel which dynamically distributes the files for backups amongst them. This feature optimizes and speeds up the backup of dense NAS volumes or shares.
Maximum number of streams per volume: The value determines the number of backup streams that are deployed for backing up each volume. For example, If a policy contains 10 volumes, and the value of this parameter is set to 4, then you see a group of four backup streams for each volume. So, a total of 40 child backup streams and 10 parent backup streams run during the backup.
