Yes staging does all the cleanup that you need, but the
information will be on disk for a minimum of one day/24 hours
(function of the software) before it will be staged.
You can overide that manually by staging the disk volume whenever you
feel like it, but
that defeats the purpose of doing it automatically.
I don't use rman, I shutdown the databases, clone the filesystem, bring
up the databases
and send the clones to backup (disk). My databases are then left on
disk for 2 days before
they are staged, and I have room for 3 days worth of databases, incase I
have problems with
the autochangers and their ability to keep up.
Depending on what you backup for your entire enterprise, staging keeps
our tape drives running 24 hours a day.

This sounds interesting. I'll investigate.
So that I might save some trial and error investigating I will ask:
What we do is IMMEDIATELY copy the most recent rman files to tape upon
completion of the rman backup; then upon successful completion of
copying
the most recent files to tape, delete the previous day's backup. Does
staging do all of this for you automatically (i.e. delete the files you
want
deleted)?

Legato has a feature called staging, which we are using. In short,
we backup up to disk, then based on age of the files, 2 days, 5 days,
7days,
the savesets are moved to tape. Works great.
