TL;DR My backup external usb drive failed. No data loss though. Move along, I'm just telling a story because my family doesn't provide good audience.
So, my backup has been a 16TB external drive for years. As it was nearly full, I decided to scrap together some parts and make a ZFS backup machine and add some automation.
All was well, I decided to do a manual backup to the external drive to grab some incremental changes before I started a full snapshot receive on the new backup machine.
Fast forward 5 hours, I concluded the external drive was done. A few days too early, but I was already implementing its replacement.
Please, all, return to your previously scheduled programming, and remember, even if you can't do 3-2-1, do something! Backup Drives Matter
