Currently we do RMAN backups for a small DB which essentially uses a single stream with multiple jobs kicked off (i.e. it would only use one tape drive if it were still going to tape).
We also do full filesystem backups for a couple of very large DBs after shutting down the DBs completely. For those we allocate 4 streams which go to 4 tape drives. There is a question from DBAs about whether we could move do an RMAN backup rather than filesystem so as to avoid the downtime on the DB. My main question is how would we setup an RMAN policy so that it uses the 4 tape drives (and only 4)? For existing RMAN there are no streams listed so my assumption is that this is all controlled in the RMAN config scripts rather than at NetBackup policy level. Also does anyone have an idea how much time difference an RMAN backup of a live database might take as compared to the cold backup of filesystems for a quiesced database? Please don’t suggest doing Mirror BCV or filesystem snapshot instead. We’re already aware of such options but are currently looking at the RMAN question.
