Cloud storage – u:cloud

u:cloud offers all employees and students of the University of Vienna storage space for their data in the “cloud”. The storage space amounts to 50 GB. You can access the data from most devices and from anywhere. u:cloud is particularly useful for temporary storage, collaborative editing of documents and for sharing data easily.

For collaboration in projects, working groups or teams, the ZID recommends using u:cloud pro.


  • The u:cloud is not suitable for storing a large number of rapidly changing, especially machine-generated files.
  • The ZID strongly advises against using external cloud services, such as Dropbox, Google Drive, OneDrive, Skydrive, Sugarsync, Ubuntu One, iCloud, etc. For these services, the ZID does not provide any support.
