Description of the illustration rep_readonly

The illustration shows a database DB-a hosted in a local data center and was serviced by a Recovery Appliance, RA-x. However, the Recovery Appliance, RA-y, in a remote data center is to begin receiving backups from DB-a. Because the original RA-x is available to RA-y, a replication server for read_only mode is configured in the protection policy for RA-y and designates RA-x as the downstream. All backups for the databases in the policy that exist on the downstream are retrievable when and if needed from the upstream. After the old backups on the original RA-x have expired according to the protection policy, RA-y will have no need for the backups on RA-x allowing RA-x to be transitioned out of the backup scenario.
