Is that 5TB school work, or are you using it for personal files too?
They write some essays, store some PDF's, share some Google Docs documents, use a music streaming service, and don't download YouTube videos.
Seems acceptable for schools to start enforcing acceptable-use policies that exclude using these accounts for anything but schoolwork if it saves money and resources to spend on other things.
Any pointers good sir/mam on how to have their own physical backups? Like NAS and others?
moreover, some youtubers remove their stuff
Why did you think your university account was for "whatever random crap I want to put in it", and also as much data as I could ever want to use"?
