Oh - one more thing, have you considered hot-backups?  It's doable via
script with plain Netbackup or using Oracle RMAN and the Oracle Agent.

In either case, the DB has to be in archive-redo mode.

About scheduling, a backup-to-disk is scheduled just like a backup to tape.
The vault product will let you schedule a duplicate disk-to-tape or without
vault you can use a cron job and a script.

Subject: [Veritas-bu] Staging backups to disk for Oracle on NBU 3.4,
Solaris 8


Good afternoon;
   I'm curious about using a disk Storage Unit for staging cold backups of
an Oracle database. Is it that much faster than going right to tape in
practice? Is the setup very complex? Can I fake this without buying Vault or
the Oracle Agent? Or should I just suck it up and buy one or the other of
these?
   I've been re-reading Mark Donaldson's script from 9/15/03, and frankly,
it's making me a little woozy.
   Right now, we do cold backups of our Oracle databases, for simplicity's
sake. I'm getting pressure to shrink the backup window, and staging my
backups to disk seems like a quick way to do so, with the side benefit of
speeding up restores (until I expire the images from the disks). Will I
really buy much time? And do I need the Vault software?
   Also, does NBU handle both backups (to disk, and then to tape) on a
schedule, or do I need to schedule one of these via cron?
   We run NBU 3.4 Data Center right now, on all Sun equipment (clients at
2.6 & 8, three Media Servers, two L9s and a one-drive L25). If I want to add
anything -- like the Oracle agent -- I'm afraid that I'll get backed into
upgrading my whole setup. Which would be fun in theory, but a burden in
practice. :7)
   Thanks in advance for any pointers.
