When it comes to backups, we also rely on multiple solutions rather than just one. For example, our main data centre is completely mirrored in a second, geographically separate data centre. In addition, all the virtual servers – approximately 50 – are backed up around the clock via Arcserve UDP to a protected and stand-alone storage area. This type of backup allows quick access to various restore points for all the data and machines. These backups are then stored on parallel LTO-8 drives, with the required tapes made available by an automatic library. Once the weekly backup is complete, the current tape is stored in a fireproof safe. Additional cloud backups for Microsoft 365 – e-mails, archives, OneDrive – round off the backup concept
