I know that for data storage the best bet is a NAS and RAID1 or something in that vein, but what about all the docker containers you are running, carefully configured services on your rpi, installed *arr services on your PC, etc.?
Do you have a simple way to automate backups and re-installs of these as well or are you just resigned to having to eventually reconfigure them all when the SD card fails, your OS needs a reinstall or the disk dies?
There’s lots of very good approaches in the comments.
But I’d like to play the devil’s advocate: how many of you have actually recovered from a disaster that way? Ideally as a test, of course.
A backup system that has never done a restore operations must be assumed to be broken. similar logic should be applied to disaster recovery.
And no: I use Ansible/Docker combined approach that I’m reasonably sure could quite easily recover most stuff, but I’ve not yet fully rebuilt from just that yet.
