Dennis,
The cron job can run on B only if it is the same version of Oracle that is
on A.

Subject: RE: RMAN - Remote vs Local Backups
Walter - What you describe is the standard RMAN configuration. Box B
contains the RMAN catalog, therefore it must command the backup. And so
the
cron job must run on Box B. But the actual backup occurs on the target
machine (A in your example). If you back up to tape, you must have an MML
(Media Management Library). You can also back up to disk (that is what I
do).
Since the actual backup occurs on the target machine, not much network
traffic is involved. RMAN sends some commands, the target sends some
status
back, and that is about it.

Thanks Tim, Dennis and Ron for your feedback. I appreciate it.
Let me clarify what I'm seeking. In my example, I am using a centralized
catalog which is on its own dedicated database/server and backups are to
tape. BCV's are not involved.
Normally, in my experience, RMAN backups are initiated from the target
server via a cron job. But, I've seen a case where a cron job for an RMAN
backup was run from a box that was different from the database server
machine. I find this configuration strange and confusing because it
implies
this was done for a "reason" and makes life difficult to find out where
all
the backups are running from.
In the scenario of backing up the database on box A via an rman/cron job
on
box B, is this particular configuration more network resource intensive
and
therefore slower versus the backup being initiated from the same machine
as
