Anyone performing full and incrmental backups of Oracle

We run a level 0 on Friday night and a combination of level 1's and 2's
the othter nights.

We just started inc backups, prior to that we were doing fulls each night.

We would run a delete obsolete rman command after the full backps to keep 3 
levels
This wasnt changed when we went to incremental. I noticed in one of the log 
files
this morning that rman deleted one the backup pieces created during the level 0 
backup

I dont think this should be the case. If we wanted to restore the level 0 we 
would be missing files

What are the optimum RMAN retention policies and TSM retention policies for 
Oracle

They must be different between using always full backups or a combination of 
full and inc


RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 3
