Backup Central

We currently use a VTL Dedupe technology and it works well but we are looking to simplify our data protection stack, and was looking at maybe getting Oracle to backup to a NFS dedupe device as a target thereby getting the backup app and associated hardware and software out of the way.

My question is if anyone is using a NFS Target Device (Sepaton, Data Domain etc) for RMAN backups and if so how's it going? I have a DBA that pointed out many Oracle / RMAN backing up to a NFS mount. Do other using these deivces see NFS issues and if so is it based on volume?

Thank you!

We do it for our development systems. I think it works better then what we do in production, but I guess the DBA's don't agree.

For production we still use the RMAN agent for NetBackup and save them off to a DataDomain using OST (NAS based).

It works well both ways. The biggest thing you need to consider with RMAN with De-dup is the file's per set setting, making it's equal to "1" so that you maximize your de-duplication capabilities. You may have to increase the DBchannels setting to make this work and still get good performance.

I'd suggest you test it out, play with the settings, and see what works best in your environment.

Thank you for your input. You're right about Files per set, we see that with our existing dedupe product. Have you had the DataDomain NFS mount point go off line for your non-prod Oracle hosts that use the mount point directly?

Have a good day!

I haven't had any problems with NFS mounts going off-line. The DataDomain has been very stable. Of course you'll need a very stable network as well.
