GWDG CrashPlan PROe

The GWDG CrashPlan PROe service can no longer be used as the manufacturer has discontinued CrashPlan OnPremises! As a “successor product”, the GWDG offers CrashPlan Cloud for its customers.

Important notice!!!

CrashPlan On Prem is currently not compatible with macOS 12 Monterey , so if CrashPlan is used, should not be updated to macOS 12!

Why CrashPlan?

Addressing the challenges of the ever growing amount of data on computers, GWDG offers to its users the endpoint backup solution CrashPlan PROe. This enables users to write backups of all their important data and also to restore the data easily by themselves. They can do so either by using the client software on their local device or by accessing the web interface. As all data backed up by CrashPlan PROe is encrypted, the autonomy and responsibility of it lies with the user.

CrashPlan is characterized by its intuitive and catchy user interface. By the approach of an almost permanent backup (typically at an interval of 15 min), it is an ideal solution for end user devices as notebooks and personal computers. The additional access using the web-ui and the ability to concentrate different devices in one backup account also provides basic cloud storage functionality in CrashPlan.

What does the service offer?

  1. The service offers an easy to use and easily accessible solution to give users the possibility to store and restore their precious data by themselves.
  2. The data is stored on systems at GWDG so that third party members cannot access it.
  3. As all data is encrypted by using the Advanced Encryption Standard, only the users themselves have access to their data.
  4. By using a private key (which has to be stored in a safe place by the users! ) the security can even be enhanced.
  5. The client runs in the background and can be set to use less bandwidth if the user is for an example not in a university network (LAN) but at home (WAN).
