I have a client running DDBEA with Oracle RMAN backups.

During the configuration, we configure 2 x Data Domains within the lockbox configuration.

Thoughts raised from this are:

1. How do we define retention as we have 3 policies of 28 days, 90 days and 90 days with replication. Does RMAN provide this??

2. How does RMAN choose the primary or secondary Data Domain. The primary DD supports 28 and 90 days. The secondary DD supports 90 days with replication

thanks!
