The Minimum Retention Period in the CMS machine policy determines how long events are retained on the local CA Data Protection machine (though the retention period can be manually overwritten by reviewers in the Data Management console or iConsole, or by a trigger‑specific Minimum Retention Period in the user’s policy.
CA Data Protection ignores the Centera default retention period. For example, if the CMS’s Minimum Retention Period is set to 365 days, and its Event Purge Frequency set to 1 day, then an event purge runs daily on the CMS, deleting events more than one year old from both the CA Data Protection database and the Centera.
Note: The Minimum Retention Period on an Event Import machine (or any CA Data Protection server) does not determine how long blobs are retained on the Centera. Its purpose is solely to determine when events become eligible for purging from the local CA Data Protection machine.
