|And, of course, you have a plan for backing up the dedicated PC, including off-site storage, so you don't lose the entire office's mail back-ups, right?|
And, of course, everything will backed up in such a way that you could restore the back ups to completely different machines should the backup PC or the user's PCs suffer a major melt down.
It doesn't help to have a bunch of back-ups that can't be restored because technology has moved on and you can't rebuild the original environment.
And, or course, all back-up and restore procedures will be documented, tested, and available to anyone who might have to perform the recovery operations.
Ah, Disaster Recovery...the memories that brings up from my days in Data Center administration.
