Automatic backup

Dear fellows,
I have now setup a nightly backup job for the following artifacts:

1. source code (not a real problem, since it is distributed over many computers)
2. Tickets
3. Discussion
4. Blog
5. Project Files like e.g. Thesisarbeiten
6. Wiki

Hope this will save us some headaches in the future.

Important note: At the moment the attachments from tickets etc are not backuped.

Happy coding

Marcel
