Monitoring the MSDP deduplication rate
The deduplication rate is the percentage of data that was stored already. That data is not stored again.
The following methods show the MSDP deduplication rate:
On UNIX and Linux, you can use the NetBackup bpdbjobs command to display the deduplication rate. However, you must configure it to do so.
See “To configure the bpdbjobs command to display the MSDP deduplication rate”.
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.
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.
