What version and edition of Oracle?
Use RMAN, that's what it's there for. You can backup online, or
offline, full or incremental.
At my last company we ran Oracle 10gR2 standard edition connected to
a small fiber channel SAN. I wrote a script that put the tables on the
primary server in hotbackup mode, then snapshotted the Oracle volumes,
and mounted the snapshots onto a virtual machine that was running
software iSCSI. From there a job kicked off and ran RMAN to backup
the database.
Prior to that we ran enterprise edition and was able to run RMAN
directly from the physical standby server. With standard edition
you can't do that.
The migration from Oracle EE to Oracle SE probably paid for the
SAN in itself let alone the massive increases in productivity
gained by the flexibility of a centralized storage system(copying
production data went from ~2 days to about 1 hour, copying data
to reporting database went from ~8 hours to ~10 minutes).
You can also run RMAN against the primary system as well(any edition
I believe), though I didn't want to do that as it'd impact
performance.
