Yes, the PST files will be bigger given that they store all the messages and
attachments for each mailbox in seperate files. If you have a lot of mail traffic to
internal groups you will notice the growth as Exchange only needs to store 1 copy of
an attachment per database regardless of the number of recipients, wheres each
relevant .PST will have a copy.
On the plus side, however, ExMerge does not need to be run on the Exchange server
itself. You can create and archive the .PST files on any TSM client that has the disk
space (perhaps older, cheaper disk).

PSTs increase the overall backup significantly. The PSTs could be 5 - 10
times the size of the exchange infostore.
We do use our long term backups regularly and have run into a number of
problems using the whole DB. OS level of the restore server, SP level of
exchange, log file problems on the starting of the IS and very long restore
times for 40Gb db from DLT7000. A lot of things can happen over a three year
retention period.
Backing up the PSTs may be a decent idea if your DBs are not that large or
you can spare the space.

I assume that a month end backup will be used to restore individual mail
items/boxes where required sometime down the track. How about using ExMerge
(sp?) to create .PST files once a month and archive them? Should make
restoration much easier as well as being a simple task to create and track
the archives.

Subject: Month End Strategies (TDP for Exchange)
I'm wondering what the best strategy to get a month end backup of
Exchange going. We would like to keep the backup for an indefinite
amount of time (most likely a few years). The backup tape(s) will
be
sent offsite. Currently we have a nightly backup of Exchange which
expires after 30 days.
I have a couple ideas on how to accomplish this. I want to hear
what
other people are doing. Thanks in advance.
