The applications the Stadtwerke Hannover are running in the open systems environment comprise not only business solutions like SAP R/3 but also a number of specialised applications for energy providers.

"In the Open Systems arena we have about 1.2 TB of data and estimate that by the end of 2000 this will have grown to 2 TB!. That´s why we need a high performance, flexible and easy to use backup tool." MICHAEL SCHULZE-GENSCH HEAD OF SYSTEM SERVICES

The data deriving from these applications should be given the same safe protection as the mainframe data. After an intensive two month preparation phase together with the project team from COMPAREX the Stadtwerke Hannover decided to implement Legato NetWorker as backup software. The main reason for that was, that via a special cloning procedure stored data can be mirrored to a second distant archiving system - very similar to the backup concept in the mainframe environment.
