All Data is stored on hard disks, which are in a RAID group. A data rescue does not represent a problem even in case of a hardware defect. Additionally all critical data is stored on an external server every 24 houres.

The continuing working is ensured even after a complete server malfunctioning. In that case a second server takes over all tasks immediately.

With a power failure our uninterruptable power supply provides for that all servers have enough time to power down normally.
