PCs have been almost ubiquitous for 20 years now. For my entire freaking life I have been hearing about how "you need to back up your data". We have consistently made better and better backup tools, like mozy, or backblaze. Yet somehow it is our fault some idiot decided "It won't happen to me!". At some point, we just have to have the users be a tiny little baby step of a bit responsible for their stuff too. Just like accounting makes people responsible for their inventory and expense reports. Just like HR makes people responsible for their own insurance stuff. Sure they help, but crap - people need to be a little grown up in their lives and actions.
Just because this person did not bother to find out about backups from her IT does not make it ITs problem. Hell, you don't even know if there was or wasn't the ability for backups in place. Most university IT shops have lots and lots of capacity and backup options in place -- and they are documented, they just don't force users to do it. You know why? Sanctimonious asshats come from the other direction then, complaining not about how IT must mother the employees, but instead must back off the draconian rules to make users feel more welcome.
tl; dr -- Users should be held to some standard of responsibility and IT is damned when they do and when they don't.
