Hi, The documentation for oracle say:

Backing up standby files is often better than backing up the production files, for the
following reasons:
n Because the standby database is not the production database, a standby backup
does not interfere with transactions or batch jobs in the production database.
Hence, you can use the standby database as a backup host without interfering
with the production system.
n If the standby and primary databases are on separate hosts, then standby
backup operations do not consume CPU cycles, allocate memory, or consume
other resources on the production host.


Oracle9i - Recovery Manager User's Guide Release 2 (9.2)

Backup Physical Standby Database And you say primary, Why????

the reason that give the documentation is very good.
but that have procs and cons..
-procs:primary db recource not interfe with backup system running
-cons:you must always monitoring tranportable archivelog from primary to standby because if not your backup is just wasting time...and some change in primary db can't update standby..hmm.like creating datafile..(am i right?)

so i think DreamzZ answer is very good to apply for decreasing blunder in database

sory if my analysis wrong
i'm beginner with this ^^
