About your only other option is to incorporate storage nodes into your
environment. That would depend on the amount of data. If you have an
oracle server with 500GB or more of data to backup, then it would make
sense to make that oracle server also a NW storage node to get the LAN
free backups.

I am a huge advocate of ASM. From a storage perspective, it is
completely controlled by the DBAs and requires no storage management. I
think the unix admins like it for the same reasons.

Powersnap uses the OS file system for creating snapshots. Since ASM is
actually a live database, the snapshot cannot make it consistent. I'm
not a big fan of ASM.

The NMO module should be able to have reasonable performance. How big is
your database and network connections. You can setup multiple streams in
NMO to greatly increase performance. For example:

run {
        set command id to 'HIST';

        allocate channel t1 type 'SBT_TAPE' parms
'ENV=(NSR_DATA_VOLUME_POOL=OTAFull)';
        allocate channel t2 type 'SBT_TAPE' parms
'ENV=(NSR_DATA_VOLUME_POOL=OTAFull)';
        allocate channel t3 type 'SBT_TAPE' parms
'ENV=(NSR_DATA_VOLUME_POOL=OTAFull)';
        allocate channel t3 type 'SBT_TAPE' parms
'ENV=(NSR_DATA_VOLUME_POOL=OTAFull)';

        backup database filesperset  4 force format='/%d_DATA_%U/'
        plus archivelog filesperset 16 force format='/%d_ARCH_%U/'
        delete all input;

        release channel t1;
        release channel t2;
        release channel t3;
        release channel t4;
        }

This will get you 4 streams.

Recently we have mograted most of our Oracle database running in 9i to
10g with ASM. But Networker's powersnap module does not support Oracle
ASM. If you are having 10g ASM databases how are you backing up the
database. We are taking it using NMO module over LAN, but is there any
better way we can improve this.
