My off-site copypool data is for recovering my applications somewhere else
if my datacenter fries or gets flooded.

I've only the one ADSM server, unlike Dwight -- but we've successfully
recovered ADSM and our SAP database at the D/R center a number of times.

And I don't use DRM either. I don't have the time window to copy my SAP
backups, so I check the originals out and ship them off-site. DRM can't
handle that. Everything else gets backed up to copypools and the copies go
off. This includes two sets of the oracle redo logs (on seperate copy
pools), so if I can't read the SAP backup, I go back a day and start over,
with an extra day of redo log to process.
