    very first RMAN backup for a target DB

    I have a DB running in archivelog mode with 2GB of archive logs. This DB has never been backed up by the RMAN catalog I just set up. I wonder when I do RMAN whole DB inconsistent/hot backup for the very first time, I can use BACKUP DATABASE PLUS ARCHIVELOG, what archived logs are backed up? I suppose it backs up ALL the archived logs it can find because this is the first time it backs them up? However, is it really necessary to back up ALL the 2GB archived logs along with the DB files, etc.? Chances are most of the older archived log will not be used even if I have to do a recovery from this whole DB backup. Am I correct?

    I suppose when dealing with this kind of situation, it's better to mount the target db and do a cold rman backup first?

    Thanks,
