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
- In the NetBackup Administration Console, expand Media and Device Management > Credentials > Storage Server
- Select the deduplication storage server.
- On the Edit menu, select Change.
- In the Change Storage Server dialog box, select the Properties tab. The Deduplication Ratio field displays the ratio.
To view the MSDP deduplication rate for a backup job in the Activity Monitor
- In the NetBackup Administration Console, click Activity Monitor.
- Click the Jobs tab.
The Deduplication Rate column shows the rate for each job.
Not all columns appear by default. Click View > Column Layout to show or hide columns.
To configure the
bpdbjobs command to display the MSDP deduplication rate
- Add a DEDUPRATIO BPDBJOBS_COLDEFS entry in the
bp.conffile on the media server on which you run the command.
The bpdbjobs command then shows the deduplication rate in its output.
Many factors affect deduplication performance.
