Lost the first five years of my source code thanks to a Deathstar. Still miffed about it, would have enjoyed looking back at it from time to time.
Learned a valuable lesson in backups though...
Same, that was also my lesson that RAID is an availability mechanism, not a data safety/backup one. (Of course, Ransomware would also hammer that point home for many later on)
My first 5mb winchester failed every day. So the day began with reformatting it and restoring from last night's floppy disks backup.
