# Configuring Multiple Streams for Backups

You can configure multiple data streams per subclient for data protection operations. Using multiple streams, you can back up multiple paths in a subclient concurrently. Because multiple paths are backed up as part of the same job, the total number of running jobs is reduced. Multi-streaming is dependent on the number of available resources (drives) and the type of file server you are using. Configuring multiple streams is useful in the following scenarios:

- A subclient contains multiple data paths.

- A subclient is configured to back up the entire file server.

## Considerations

- The actual number of concurrent backup streams employed during a backup job is limited by the number of subclient content paths. The number of available resources will be limited if other subclients are also using the same Storage Policy or a specific content path requires more time for backup.

- Isilon backups: You can use multiple streams to backup individual content paths to increase the speed of backup operations. For more information see, Isilon Multi-Streaming Backups.

- NetApp IntelliSnap backups: Subclients with multiple content paths on the same volume will only use a single stream per volume when cataloging the snapshot.

## Procedure

1. From the Command Center navigation pane, go to Protect > Files.
