Ask HN: What's your backup setup?
To each of you guys having those extensive backup solutions (like NAS + cloud sync, second nas, etc)...<p>.. do you actually TEST those backups?<p>This questions comes from my experience as a system engineeer who found a critical bug in our MySQL backup solution that prevented them from restoring (inconsistent filesystem). 
Also, a friend of mine learned the hard way that his Backblaze backup was unrestorable.
