I have Oracle 8i Enterprise Edition installed on Sun OS Unix servers. The database is run in archivelog mode and I am taking a hot backup of the database using rman every night.

Since this is on a development database where we are testing our backup and recovery mechanisms, we want to keep just a couple of days worth of data and delete older ones. May be this is a very basic question, but I wanted to know if I could just list all the files and delete the old ones by the date and time of creation of them. Or are they all related in some weird way...)).
