Ransomware will encrypt the backups too if it can. If the backups are stored on a server or network drive they are toast. Best way is to backup using tapes, which few organizations do in the age of the cloud.
I assume that someone capable of running a big University infrastructure is aware of that and stores backups in a separate, preferably offline server. But yes, this can happen, but backups in a separate server are guaranteed to make things better and easier when being attacked.
They only attack vector that wont ever be fixed is called humans

True

give it a week and one of their own pupils will probably use the script to make the ransomware. load it onto his colleges servers and ransom the college himself
That would be absolutely despicable.
How ironic would it be if this fiasco actually helped increase bitcoin awareness in that university leading to more adoption there.
Haha, it would be amazing
