Last published : Apr 02, 2026
You can view all of the properties of an OpenStorage device and you can change some of the properties.
To edit the properties for an OpenStorage device
  1. On the Storage tab, double-click the name of the OpenStorage device.
  2. In the left pane, select Properties.
  3. Change the following properties as needed:
    Name Indicates the user-defined name for this OpenStorage device.
    Description Indicates the user-defined description of this OpenStorage device.
    Backup Exec server with device proximity Indicates the server that you want to run backup operations when the OpenStorage device is shared between servers in a Central Admin Server feature environment. You can specify a Backup Exec server that has physical or logical proximity to the OpenStorage device. Proximity of the Backup Exec server to the device is an advantage when the device is the source of a job, such as a duplicate job or a verify job, and you want to avoid running the job over a WAN.
    By default, the Backup Exec server on which you create the OpenStorage device is the server that runs the backup operations for the device.
    Logon account Indicates the name of the logon account that is required to access the device.
    Concurrent operations Indicates the maximum number of jobs that you want to run at the same time on this device.
    Split data stream every Indicates the size at which you want Backup Exec to span to a new image. The default size is 50 GB.
    Data stream size Indicates the size of a single write operation that Backup Exec issues. The default size varies based on the type of device that is being used.
    Stream handler Indicates whether stream handler is used. Backup Exec sets this option automatically when you select a server type. For some types of devices, this option does not appear at all. If Backup Exec does not set this option, contact the device's vendor for the recommended setting.
    Client-side deduplication Indicates whether client-side deduplication is enabled for this OpenStorage device.
    Client-side deduplication enables a remote computer to send data directly to an OpenStorage device. By using client-side deduplication, the Backup Exec server is bypassed, which leaves the Backup Exec server free to perform other operations.
    Disk space to reserve for non-Backup Exec operations Displays the amount of disk space to set aside for applications other than Backup Exec. The default amount is 5%.
  4. Click Apply to save the changes.
