Re: Copying Large Amounts of Data From Prod to Dev

Peter,

We're currently running a 4.8TB Oracle SAP instance that's getting pushed back to QA and/or DEV several times a month. I'm using the RMAN duplicate command against two IBM 3592 Tape Drives. The DBA time on this is really minimal. I've actually got it all scripted, and the restore time varies between 8-10 hours. Post-processing by our Basis Team takes from 45 minutes to an hour. I can kick it off on a Friday night (or whenever) and generally, somebody from our Basis team does the post stuff (license install, user configuration, printer configuration, etc.) early Monday morning and it's ready to go when the Developers and QA folks come to work.

The disks are 15000rpm 73GB in RAID5 arrays, and the tape library is fibre-connected to the servers.
