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'm not sure what Ansible does that a simple Docker Compose doesn't yet but I will look into it more!

My real backup test run will be soon I think - for now I'm moving from windows to docker, but eventually I want to get an older laptop, put linux on it and just move everything to the docker on it instead and pretend it's a server. The less "critical" stuff I have on my main PC, the less I'm going to cry when I inevitably have to reinstall the OS or replace the drives.

I just use Ansible to prepare the OS, set up a dedicated user, install/setup Rootless Docker and then Sync all the docker compose files from the same repo to the appropriate server and launch/update as necessary. I also use it to centrally administer any cron jobs like for backup.

Basically if I didn't forget anything (which is always possible) I should be able to pick a brand new RPi with an SSD and replace one of mine with a single command.

It also allows me to keep my entire setup "documented" and configured in a single git repository.
