Um -- if your DB backup is that old, yuo've got other REAL problems in your
D/R environment or specifications.

Our requirement (set by the executive board) is to recover, within 48 hours
of the incident, to within 24 hours of the start of outage. If your database
backup is that old, it implies that anything done in the last three months
is of no value . . .

Say for a moment you're faced with recovering a TSM server in a DR
situation. You have your DB backup and copypool tapes and perform a database
recovery. If that DB was created back in January and it's now March, isn't
there a potential for objects getting expired the first time you start the
TSM server? E.g. when the TSM server is started it typically performs an
expire inventory as part of that sequence. I would imagine that now that
it's 2 months later, would it therefore start expiring objects that you
probably don't want to have expired?

If not, why not?
If so, whats the appropriate step to take before starting the TSM server (or
perhaps even before recovering the DB) to ensure expire inventory doesn't
ruin your recovery? I recall there being an option in dsmserv.opt that
allows you to turn off automatic expire inventory. That seems like a good
idea.. but what if there was an admin schedule that runs expire inventory
back then and you happen to start the recovery while in the schedule's
window?

I think you can see what I'm getting at with all this. I want to make sure
all my bases are covered..
