In a corruption scenario clustering/SRDF buys you nothing, you are going to
tape to recover the server.  Snapshot technology might make a difference,
but in general you need to take into account the size of the databases on
the server and the number or logs that you generate in a day.  Only way to
know for certain is to test.  Look for things like how fast it takes your
recovery process to process a log.  What is your backup/restore times in
gigs per hour? NTbackup restores between 15-19gig an hour with local tape.
Fibre based backup might get 30gig an hour depending on the tape device, new
tape equipment will get you close to 90gig an hour.  How long does it take
for your team to get in gear to start the process?
Then you have a host of other options.. empty mailbox scenario, exmerge data
back....causes more work for you, but gets users to new e-mail asap.  In
this scenario exmerge contact/calendar data first... people need to know who
to call and where to go.
Reverser Exmerge similar to empty mailbox, but you run all day with empty
data.. while you spin tape.  end of the day you take the server down replace
the DB, then later exmerge the days data back to user mailboxes.  Keep in
mind that both will cause Blackberry server to stop redirecting e-mails.
Brings you to another topic  dependencies...Blackberry servers....other
applications that you need to recover.
I guess what i am saying is that you really need to sit with management, ask
them how fast they need e-mail back.  This will determing your approach,
mailbox size, number of times you back during a day.
blah blah blah...

Subject: [exchangelist] Restoring an Exchange Server

We have a Win2k server, running as a domain controller as well as housing
our Exchange 2000 database.  It also holds documents, user directories, and
acts as the main server for our Antivirus Corporate edition.
We had a raid controller fail and a whack of
system/exchange/program/data/documents all kinds of files were corrupted.
I know need to rebuild this server somehow and I was wondering how I would
go about doing this?
My idea is to bring up another win2k server, and install exchange on it and
migrate the mailboxes over?  
Has anyone had any experience with this or any recommendations?
