Monitoring the MSDP deduplication and compression rates
The deduplication rate is the percentage of data that was stored by the deduplication engine. That data is not stored again. The compression rate is the percentage of space that is saved by compressing the backup data before it is stored.
The following methods show the MSDP deduplication rate:
For the method to show the MSDP compression rate, See Viewing MSDP job details.
On UNIX and Linux, you can use the NetBackup bpdbjobs command to display the deduplication rate. However, you must configure it to do so.
To view the global MSDP deduplication ratio
- Open the web UI.
- On the left, click Storage > Disk storage.
- Click the Storage servers tab.
- Click the storage server name to view the global MSDP deduplication ratio.
To view the MSDP deduplication ratio for a backup job in the Activity monitor
- In the NetBackup web UI, click Activity monitor.
- Click the Jobs tab.
The Deduplication ratio column shows the ratio for each job.
To disable the display of the compression rate separately:
Open the
pd.conffile that is available at the following locations:Windows
<install_location>\lib\ost-plugins\pd.confUNIX
/usr/openv/lib/ost-plugins/pd.confAdd the following parameter in the file:
DISPLAY_COMPRESSION_SPACE_SAVING = 0
You can remove this parameter or change the value to 1 to turn on the display of compression rate as a separate value.
Many factors affect deduplication performance.
