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?
My server has a raid1 mdadm boot drive. And an 8 dive raid6 with zfs. It’s been running for 14 years now. The only thing that I haven’t replaced over it’s lifetime is the chassis. In fact the proc let out the magic smoke a few weeks ago, after some new parts it’s still going strong.
