Science can build a better machine, but human nature will always trump 
it with a better idiot.

If you can get away with a PXE boot, that would probably be best, but 
nothing will protect the user's data created on the PXE session... 
Perhaps an hourly/half-hourly/quarter-hourly rsync to a backup machine 
without the '--delete' flag? That will protect against deletes, but not 
corruption of the file(s). Alternatively, have four rsync's run to four 
backup sources every other 15 minutes with a nightly to a fifth 
location? Would give you 24 hours to realize you snarfed a file.

In short though, I don't think you can... Not truly and not even close 
without significant investment. How close you can get depends on the 
amount of time you expect to pass before screw ups are realized and how 
far back in time you want to be able to recover from.
