Well, feel free to come visit. How can I document that our environment
works?

Yes, the system _does_ take care of that. Just back up the data, and the
consistency checks gets done.

Sure, I'll set up your backup environment for you. Grant me remote access
and we're in business, as long as you are willing to run the backups in a
_proper_ way, we can certainly prevent future corruption.

Curiosity here; Exactly which tools is that you have used? Backup Exec will
catch it, ARCServe will catch it so on, so forth.
And _how_ have you backed it up? You say that you use flat file, file system
backups. Which I have stated _will not_ check your data for you.
>I DO HAVE CORRUPT E-MAILS AND DATABASES
Well, you should do something about that then.

Well, I have been running exchange environments for 50 user offices, and for
7.000 user enterprises. I have had corrupted databases, but it has never
been a complete shut down. It has never been any been more of a problem then
to revert back with a point in time recovery, or usually one or two corrupt
mails, which usually is easy to bring back from a mailbox-backup.

Yes, they certainly should do that. But, my personal recommendation would be
to add an agent based backup to the set up. Both Backup Exec and ARCServe is
simply faster then NTBackup, and the level of possible automation is
excellent.

Well, with just your "success story" people may be reluctant to do so, hence
I thought I'd provide my own views of exchange.
