RMAN via NetBackup or Oracle Enterprise Manager/ Grid Control?

RMAN via NetBackup or Oracle Enterprise Manager/ Grid Control?

Post by Hope Dunda » Sat, 29 Apr 2006 03:26:54


Hi folks, I'm new here, and I had a question, hopefully not too
dumb/ignorant. :)

We have two Oracle RAC Clusters running Oracle 10g and an Oracle
Enterprise Manager/Grid Control server from which we normally manage our
RMAN backups.

Our backup software is Symantec/Veritas NetBackup Enterprise, which has
an Oracle option. I'm trying to figure out what, if any, benefit we
would get by using NetBackup to do the RMAN backups - my instincts say
that it's better to stick with the Oracle-native solution, but perhaps
some of you have experience to the contrary? Are there any good reasons
to use NetBackup to manage the RMAN backups?

What I'm planning on doing is doing RMAN backup-to-disk within
Enterprise Manager/Grid Control and then have NetBackup just back up the
backup files on disk.

A bit more about our environment, in case it's relevant:

Oracle 10gR2 (10.2.0.1.0) running on two-node RAC cluster on Windows
Enterprise SP1, on Dell PowerEdge servers. Storage is on an EMC SAN, and
the data files live in ASM. I don't think NetBackup can easily access
ASM - but I've figured out that I can set the backup-to-disk location to
non-ASM space just fine, which gets around that issue.

Much thanks in advance for any advice you can offer.

Thanks,

If I was just going a RMAN backup to disk, my instincts tell me to just
schedule this in OEM. But you will have to ensure that you have enough
lag time to get the backup done before NetBackup picks it up. That being
said, in a Legato/RMAN solution I implemented, I let Legato start my
RMAN backup and then have Legato backup my RMAN backup sets to tape
right after my RMAN backup was done. This way, it is a continuous operation.

Cheers,
Brian

Netbackup just calls RMAN. It doesn't offer much more.

Netbackup with the RMAN option basically allows you to write(and read)
directly to tape, I've let Netbackup handle the scheduling.
