Backup- / Redundanz-System
The folders /etc and /testbedhome are only for backups.
The folder /src is a mirror and thus provides a better reliability (redundancy). If the master server breaks down we still have the slave server to take over.
Historically we had a ressource problem on the master server. To solve this we moved the folder /testbed_data to the gateway server. This folder is now mounted remotely by the other servers.
