I've always heard that you folks like to keep tons of backups of your stuff. I have also heard that there is this 3-2-1 rule about keeping you backups. My question is: do you follow it personally or is it something that people just tell you to follow?
Locally, I have RAID on my NAS, my sentimental stuff is mostly synced with other systems through seafile (similar to nextcloud), and is also backed up to backblaze.
