Hi Netbackup Gurus!

We are looking at developing our disaster recovery plan and the
minimum requirement is that we can restore from tapes (that are
stored offsite). At the moment, we manually run a bpbackupdb to a
local disk and then copy the images it creates to a remote site. The
objective of this is to be able to start the restore procedure as
soon as possible (and this means we don't have to restore the
catalogs from tape). 

We would like to create a warm standby node at the remote site where
the catalogs can be restored to (perhaps automatically every night?)
so all we need to do is get the tapes and start restoring.

How do you get around the fact our second server has a different
name to the master? When I recover the catalogs I have to run:

$ bprecover -r -dhost dr-server -dpath /backup/catalogs

This is fine and it does restore the catalogs. I can now browse the
policies and pick up individual files. The only problem is it
restores the device configuration which differs on the new server.
What is the best way around this?

Real server is Sun V240 + Sun L25 (two SDLT320 drives)

DR server is Sunblade 2000 (don't ask why!) with a standalone SDLT
drive (desktop drive with no barcode reader). 

I guess what we could do is build the DR server and install the
software with the same name as the real server but this would take
too long, even if I just renamed the server, I would still need to
install the netbackup software and configure. It would be better if
all the operator had to do is recover the catalogs, find the files
required and start the restore?

I would appreciate any thoughts any of you might have, or perhaps
any success/failure stories!

Thanks
Tim.
