What do you do when you lose your files just before the work is due in? Well, in a perfect world you’d just go and get your backup. In an imperfect one (which is were we found one student today) you find that you don’t have a backup of the files that are needed.
The good (and frankly quite amazing) news is that the Computer Services folks are a lot more careful about backups than some students. Turns out that they back up the workstations and student folders every couple of hours or so. Which meant that the chap in question was able to go down to the helpdesk, tell them his username and they were able to restore the missing files. Just in time for the deadline.
I reckon it is probably best not to factor this facility into your working process. But it is jolly nice to know that it is there.
