HP Data Protector Operations Guide
To add media to the location, right-click on the media properties, and select Change Location.
Hold down the Shift key to change the location for several media at once.
The location will show the number of media added. Each medium will also show the location
details.
Performance monitoring using a nul device
Backup performance numbers are displayed at the end of each backup session as a summary.
Data Protector does not offer interactive performance monitoring for ongoing sessions through the
GUI.
If you suspect the sustained data flow to the tape device to be too low, or the device does not
handle it correctly, you can improve performance by simulating a high-speed device.
To create a nul device:
1. Create a standalone file device and a device file
o UNIX:
/dev/null
o Windows: nul
2. Create a new media pool, select the Loose allocation policy option and set the global
variable InitOnLoosePolicy to 1 in
o UNIX:
/etc/opt/omni/server/options/global
o Windows:
C:\Program Files\OmniBack\Config\Server\Options
Change this pool under the device settings of the device created in step1.
