That's what we do here, although it's (much!) preferable to let RMAN purge the backups in order to maintain it's sanity. If you purge them manually, you'll need to at least crosscheck your RMAN repository afterwards. If not, there's potential to run into errors when doing backups. At least I did, on, when I ran out of diskspace due to a bug in the retention policy and I forgot to crosscheck after manually removing (many) old RMAN backup files.

The downside is that you will need some manual intervention in recovery should those backup files be needed but don't exist in the location where RMAN originally put them. I understand this caveat and still think it's worth the tradeoff vs. purchasing the 5-figure license to have our RMAN backups go direct to the backup subsystem (in our case, Tivoli).

HTH! GL! Rich
