In addition to all that Simon writes ("fire!"), I'd also mention that we
saw considerable support-cost savings when we introduced easy user-access
to their "yesterday" filesystems. Our front-line support teams used to
field loads of "oops, I just trashed this file, could you restore it for me
please?" calls. Now, provided the users realise what they've done, and
usually they do, they can restore things from the previous day's state
themselves.
