Data Backup / Hosting

bwLehrpool consists of the following components:

  • Satellite server, on which the administration software is provided
  • NFS Server (Network File System), on which virtual images are stored, which is booted in the computer rooms
  • bwLehrpool suite, a java-based software to facilitate the administration of the virtual machines and events within bwLehrpool. This software enables the uploading and downloading of virtual machines and the creation of events, provides for the assignment of rights to virtual machines and events and offers advanced options. The bwLehrpool suite can be used with a bwIDM login
  • Central master server, operated at the University of freiburg, which manages authorised satellite server installations and provides updates of the basic Linux system. Sends an anonymised statistics report weekly to the master server using an encrypted connection.
  • PCs in the computer rooms, which supports network boot and require sufficient memory and network bandwith

The satellite server and the NFS server are operated in the university's Computer Centre and are subject to the standard data protection policy.

It should be noted that data that was deleted outside of the defined retention period cannot be recovered.

The computers in the labs are not persistent. This means that they return to their original state with every reboot. Therefore, no data can be stored on these computers.
