NetBackup for Oracle
OK, I hope this doesn't sound to stupid as I'm really only a month into learning NBU and I realize I havn't come close to scratching the surface, but here goes.
We have an Oracle RAC that NBU is currently backing up the Oracle database on. NBU version is 7.0 and the master is Windows 2008.
Anyway, I inherited NBU and as such have spent some time over the last month slowly learning NBU.
Now I'm getting close to having to tackle creating restore procedures for our entire DR plan which NBU just so happens to be a part of.
So I start looking at the NBU for Oracle Admin guide, at the restore portion in particular, and I pretty much see nothing but references to running RMAN.
OK, so looking back at how NBU performs a backup of Oracle, what does NBU do? It calls a RMAN script that actually performs the backup.
So my question is what is NBU actually doing here other than running an RMAN script on a schedule? Why use NBU if that's all it is really doing, as using NBU just adds more layers of confusion to a disaster recovery situation taking into account NBU clients and NBU's own commands. It just seems like it adds more than is really needed.
I'm just trying to figure out why it wouldn't be easier to run RMAN independent of NBU and push the RMAN backups to a disk location where these are then backed up to tape using NBU as an archiving function.
Please let me know what the huge benefit is.
