Time machine limitations

Hi Guys and Dolls..

I'm looking for some offical apple documentation or on apple's website itself that states time machine is limited to 50 connections/users.

I'm a logger ends with this end user who thinks time machine is the solution to his backup issues as he doesn't want to save his data on the corporate storage like every other user, so he's trying to apply that every user has the data backup issue and that every user should have time machine running.

I believe it's quite common knowledge, well stated on many websites and was even brought up an a few training courses, but I just can't find any offical apple documentation stating it.

Thanks in advance.

My apple account manager has got back in contact with me, confirmed it writting and linked apple documention confirming it's limits.
