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 actually run everything in VMs and have two hypervisors that sync everything to each other constantly, so I have hot failover capability. They also back up their live VMs to each other every day or week depending on the criticality of the VM. That way I also have some protection against OS issues or a wonky update.
Probably overkill for a self hosted setup but I’d rather spend money than time fixing shit because I’m lazy.

HA is not redundancy. It may protect from a drive failure but it completely ignores data corruption issues.
I learned this the hard way when my cryptomator decided to corrupt some of my files, and I noticed but didn’t have backups.
That’s why I also do backups, as I mentioned.
yeah, there’s a bunch of lessons that tend to only be learned the hard way, despite most guides mentioning them.
similarly to how RAID should not be treated as a backup.
