=== Backup ===
The (Online) Backup Service service consists of two areas:
* '''Server''': The actual backup space with some extra functionality like informing the user when the backup space runs full or if a back was not executed at the planned time.
* '''Client''': The backup client (for example [http://www.sepiola.org/en/ Sepiola]), which is responsible to regularly copy the local data to the backup server.
