This topic should generate some interest <g>

The cited analysis is interesting, but out of date (V3.7.2).  Also, the
methodology is suspect, especially considering a Veritas engineer was
onsite to set up NBU but they set up TSM from the manuals.

There is a readable and comprehensive article on Exchange 5.5 deleted
object restore at
http://www.exchangeadmin.com/Articles/Index.cfm?ArticleID=7922&Key=Outlook%20Deleted%20Items


As I understand it, the admin enables the "deleted items cache" and deleted
emails live there awhile, easily restorable by the user.  If this facility
isn't enabled or doesn't work, the Microsoft supported approach for getting
deleted mail back is to restore the entire Exchange server on another box.
Not good.

Veritas and some others use a messaging interface to capture emails and
back them up.  This interface was never intended for backup, and is very
slow for both backup and restore.  But it does work, and the vendors do
keep up with Microsoft breakage.

At the last IBM storage conference, this came up, and the recommended
approach was to use IBM Content Manager CommonStore for Exchange Server.
If anybody has done this perhaps you could post results.

Also, Gerald!  This may be off the topic but there was a nice analysis
done on TSM vs. Veritas!  You can view it at:
