You just finished setting up all your services and it works fine - how do you now prepare for eventual drive failure? (kbin.social)

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?

I put all docker data in one directory (or rather, a btrfs subvolume) and both snapshot and back it up daily to multiple machines. docker-compose files are also kept in the same subvolume.

My latest server is NixOS, so I don't even bother backing up the root subvolume, since the actual config is tracked on git and replicated on multiple machines. If I want to reinstall, I can just install NixOS and deploy the config, then just copy over the docker subvolume, and rebuild the containers. Some of this could be automated further (nixos-anywhere and disko look promising for the actual OS install) but my systems don't typically break often enough for that to be a significant issue.

You can go even further and either just use nix for the services, or use nix to build containers themselves, but I have a working setup already and it's good enough, and I can easily switch to another distribution if issues start occurring in NixOS.
