Applicable objects:
Machine
Use the
Stream Control
page to configure the
Backup stream
setting for all objects found in a machine.
Data Protector Express is capable of controlling multiple concurrent data streams simultaneously (up to
eight streams per device). Data streams are automatically created for each machine object. To view this
setting for a specific file, directory or volume, open the
Stream Control
page for the file, directory or
volume.
NOTE: The number of concurrent data streams that you can create is controlled by your Data Protector
Express license. If your data storage needs have increased, consider upgrading your product edition to
accommodate more data streams.
To disable the default stream
The default data stream setting determines whether or not a new data stream is created for each object in
the machine. To disable it, check
Disable default stream then save your changes by clicking Apply or
OK .
To create a new stream
You can create a new data stream for selected objects. Creating a new data stream for some objects can
improve throughput between the machine and the backup device especially if an object is rather large. For
example, you might decide to create a new data stream whenever Data Protector Express backs up a
database (such as Microsoft SQL Server databases).
