I have started working with RMAN and I have seen several comments that FORMAT should never be used when saving files to the FRA. Is there a reason for that?
For example, I use some powershell to build folders with a date and DBID in their name, before adding RMAN backups to them that night. Can I still do that in the FRA or should it be left without any FORMAT rules or sub folders? If my RMAN backup script is using CROSSCHECK, DELETE INPUT / OBSOLETE / EXPIRED files explicitly, what is the advantage of using the FRA?
Thanks in advance!
