Detecting backup anomalies on the media server
This topic provides the workflow and the procedure that enable the media server to detect backup anomalies.
Note:
By default, the anomaly detection algorithm runs on the NetBackup master server. If you see any impact on the master server because of the anomaly detection process, you can configure a media server to detect anomalies.
To enable the media server to detect backup anomalies
- Install the NetBackup media server software on your system (or upgrade the media server software).
- On the media server, start the nbanomalymgmt service manually. Use the following script:
nbanomalymgmt -start
- (Optional) If you want to preserve the data that the master server has gathered earlier, do the following:
Ensure that the nbanomalymgmt service on the master server is stopped.
Go to the following directory:
On Windows: Install_Path\NetBackup\var\global
On UNIX: /usr/openv/var/global
The directory resides on the shared disk on a clustered master server.
Copy the NB_Anomaly.db file from the anomaly_detection folder on the master server to the anomaly_detection folder on the media server.
Start the nbanomalymgmt service on the media server.
- Configure the backup anomaly settings in the NetBackup web UI. NetBackup takes these settings into account during anomaly detection.
See Configure anomaly detection settings.
See How a backup anomaly is detected.
If any anomalies are detected, they are notified using the NetBackup web UI.
