No no, don't look for the book, thank google.com thats pretty much the font 
of all knowledge nowadays.

You don't need to back up multiple copies of the AD because they 
auto-replicate so that they're all the same.  However, unless all of your 
DC's are the same, you'll need a backup of each one of those.

    Putting a tape drive on each one is not a good solution.  Use something 
like Veritas which lets you back up remote servers.
