Instructions
Over time the DPA Datastore database can grow and eventually consume all space on the current file system. If and when this can occur depends on the DPA configuration for data retention. For example, this can commonly occur when backup job (jobmonitor) data retention is left at the default of "forever." If the Datastore database file system reaches capacity and no more space is available, then the database crashes and may or may not be recoverable. At a minimum, data loss likely occurs.
Below are instructions on how to set a Data Protection Advisor (DPA) analysis policy to send an alert for the Datastore database file system nearing capacity. This alert is meant to inform Administrators that the environment is nearing capacity limit before it leads to a database crash and possible data loss. The Administrators can then address the issue beforehand.
Instructions:
-
Log in to the Data Protection Advisor UI. Expand the Policies category in the left side menu and select Analysis Policies. In the right side panel, click the + CREATE POLICY button.
