So I'm trying to wrap my head around this problem. I'm backing up a 4TB
oracle database with 4 LTO2 drives, connected to the server via 1GB
Ethernet. That's not that bad of a problem. RMAN, lvl0 backups twice a
week, plus daily lvl1 backups plus archive logs. However, when you
throw into the mix that I have 20 of these servers (4TB is the average
DB size, they very from about 200G to 7TB) to back up, it gets more
interesting. I'll be able to spend money eventually, but not right now.
My eventual plan is a few fully populated SL500 libraries with 4 drives
each. In the final plan, I'd like to have 8 drives each library and
about 150TB of SAN in between the DB servers and tape drives with
serverless backup from the SAN to tape. Or, a big honkin' virtual tape
library full of disks that can do serverless backup and has several SAN
connections. =20
=20
But right now, I'm limited to 2, maybe 3, 2-drive LTO2 changers with
enough slots to back up about 8TB of data each before I have to shuffle
out full tapes. I've been pounding my head on this problem for a few
days now and every time I think I have it sorted out so it's not that
bad, I remember that I have 20 of these databases.
=20
Anyone have any suggestions?
