Hi,
Flashback is taking care of deleting the obsolete OMF on disk. That is, if you do NOT specify log_archive_dest_1 nor autobackup format, all your files in the recovery area will be deleted when obsolete regarding retention and size.
However, my question is, how would you then delete obsolete backups on tape?
RMAN> delete obsolete device type 'sbt_tape';
does not work in 10.1.0 (it is supposed to work in 10.2.0).
How can you figure out which backups are obsolete and where they are?
Thanks
Laurent
