Please note!
"In the O365 service, there are no traditional backup copies available to the user, so be careful about what you delete or replace. You can restore files removed from OneDrive within 90 days, if you have a valid user account."

"When using a cloud storage, it is good to know what kinds of work-related material can be processed there. Read the attached instructions provided by the university and follow them."

Also take note of this!

"OneDrive for Business is not the same service as OneDrive intended for consumers. Microsoft offers free cloud storage on Microsoft OneDrive, which you may use as a private storage (capacity 5 GB). Your private OneDrive storage is not connected your university username. Only it for your private needs, not for processing work-related files."
