Backup selections list directives for multiple data streams

If the Allow multiple data streams attribute is enabled for the policy, the following directives can be used to control how NetBackup creates backup streams:

NEW_STREAM
ALL_LOCAL_DRIVES
UNSET and UNSET_ALL

Note:

For best performance, use only one data stream to back up each physical device on the client. Multiple concurrent streams from a single physical device can adversely affect backup times. The heads must move back and forth between the tracks that contain files for the respective streams.
