i suggest to use a raid system, depending on your space, you can use raid1 raid10 raid50 + 2 hot spare disks + redundant powersupply + 1 lowcost mirror server to sync realtime
IX, thanks for the 2c 😄
The setup was indeed a raid 1 - the raid controller was faulty and caused both of the disks to fail without an option to restore the data.
Lesson learned the hard way 😳. We're already working on a redundant solution with multiple backups.
