Wanda,

Thanks.  That much I understand.  What I don't understand is "what does
one DO with an image backup?"  The manuals are crystal clear on how to
create an image backup, but very vague on how to use them after they've
been created.

In other words, lets say I'm recoverying my TSM system somewhere else and
I have a/some DB image backups available.  HOW do I recover using
one/them?

Thanks.

Tab

Re: DB (Image) backups






If you want to continue creating DB Backups on tape, a DB SNAPSHOT
should work nicely.
It is just an extra, full backup that is independent of the original
full/incremental DB backup series.

Subject: DB (Image) backups


We are setting up SAN replication for DR.  I need some information on
how
to handle the TSM database.

TSM 5.1.10.0 - soon to be TSM 5.3.(2?).x.
AIX 5.2 ML-3 - soon to be AIX 5.3 ML-2+

For the last seven years we've backed up the TSM DB to tape and sent it
offsite.  When we've needed to restore the DB, we're restored from tape.
Mostly works OK except a little slow.

Now we have an EMC Clariion CX500 SAN and we're setting up SAN-to-SAN
replication with our warm site.  We will have a TSM server staged at
that
site but it will be OFFLINE because of a shortage of live Fiber ports in
a
non-DR state.  Our drop-ship contract includes an FC switch.

What we would like to do is backup the DB - full and incremental - to
the
SAN and replicate those backups to the warm site's SAN.  Recovery would
involve connecting the staged recovery server to the target LUN and then
restore the replicated database volumes.

Questions:
* Would that work??
* If I wanted to continue the DB backups to tape in parallel - in other
words, maintain two DB backup sequences - how would I do that?
* The Backup DB command offers a Type=Image option.  What does one do
with
a DB image?

Thanks in advance.
