Allow Multiple Data Streams
Specifies that, depending on the directives or scripts/templates (of database policy types) in the backup selection list, NetBackup can divide automatic backups for each client into multiple jobs, with each job backing up only a part of the backup selection list. The jobs are in separate data streams and can occur concurrently.
- How many streams (backup jobs) start for each client and how the backup selection list is divided into separate streams is determined by the directives, scripts, or templates that you specify in the backup selection list. See Backup Selections List Directives for Multiple Data Streams.
- The total number of streams that can run concurrently is determined by the following settings:
- Number of available storage units
- Multiplexing settings
- Maximum jobs parameters
See Tuning Multiple Data Streams.
Note
If Allow Multiple Data Streams is in use, and a file system exists in an exclude list for a client, a NetBackup job appears in the Activity Monitor for the file system that was excluded. This is normal behavior and none of the files in the excluded file system will be backed up.
