Agreed.
We use EMC EmailExtender and EmailXaminer because NASD regulations require us
to archive all email and IM for 3 years. Otherwise, we would keep as little as
possible.

This answer is almost always dictated by your legal department. I currently am
not responsible for exchange backups, but in a previous life it was decided
(per legal) that no DR copies were to be taken for exchange, and that the
retention was 7 days.
There was no archiving done at all. We used the exchange client, and the
backups and restores were completely owned and managed by the exchange group
(similar to SQL or RMAN).
My only responsibility was to design a storage configuration that would support
the number of users they projected a server could handle, and then duplicate
that configuration on each cluster, and to ensure the backup/restore
infrastructure was always available.
You should not be the person to dictate those policies, nor do you want to be
that person. Let the legal department and upper management figure that out.
Just one example of many possible outcomes.

Subject: [Networker] Backing up a large Exchange 2007 server
Greetings everyone;
We're in the design stage of deploying a new Microsoft Exchange 2007 server
which will be clustered with several nodes. We expect that within a year after
initial deployment, we'll have roughly 11,000 Exchange users and 20TB worth of
Exchange data. All the data will probably sit on an EMC Clariion, although that
is yet to be decided for sure.
We will have a backup window of 12 hours for this Exchange server. We have a
Sony PetaSite tape library with 14 Sony S-AIT1 drives, but we do not want to
invest any money in that library due to the impending EOL of the Sony tape
media. Our backup server is Power Edition NetWorker 7.4.1 (which I will upgrade
to 7.4.3 at some point) running on Solaris 10 sparc. We also have a Power
Edition NetWorker 7.4.2 server running on a Linux box with a Qualstar tape
library with 4 LTO-3 tape drives that is underutilized, but it is in the same
room as the Exchange server will be, so we are not keen on using it to back up
the Exchange 2007 data unless maybe if we hand carry LTO-3 tapes to the
building where our main backup server is located, just for safe keeping.
If we lose the Exchange server, our objective is to bring it back online within
a few hours so people can continue to send/receive email, then recover their
old email within the next week.
It seems to me that we must include some sort of archiving solution in this
system to avoid backing up the 80% or so of email that never changes and rarely
gets read to tape. I think we should do a daily back up to disk for and then go
to tape maybe once a month for the full set of data. I figure that backing up
20TB to tape on a daily basis (or even weekly) is an unrealistic goal over a
Gige network, which is what we have in place. We could go over fibre to our
Sony tape library, but I hate the idea of investing money to do that when I
expect to phase it out in a couple of years.
I am wondering what other sites with large Exchange servers do for archiving
and backups and what your requirements are for your backup window and recovery
time objective.
