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?
Once a… year? There’s a lot that can change in a year. Cloud storage can be pretty cheap these days. Backup to something like backblaze, S3 or Glacier nightly instead.
You can save periodically to it like once a month but keep one as a yearly backup.
