Re: Monthly RMAN Long Term Backup

"to be run monthly to get a full backup of the database and keep that backup for a year"

This is a bad policy. A backup is supposed to allow recovery to a point in time with zero data loss. These monthly backups will never be used like backups are meant to be used. They could be dangerous to your database if someone restores them without knowing what they are doing. If there is a justified reason to store snapshots you should just do an export and keep that however long is needed.
