I'm in the self-hosted camp as well with two Synology NAS boxes in two different countries that all of the family's computers synchronize to using Syncthing. Each of the boxes runs a local backup to an external drive nightly and one of them also runs a backup of a subset of (really important) folders to Backblaze. This uses Synology's proprietary backup tool (HyperBackup) which I intend to replace with an open source solution (most likely rclone but I'd be interested in suggestions). As an additional measure I rotate the external drives in one location weekly. So far it proved quite reliable when switching machines (in combination with git-managed dotfiles and stow) and accessing data on demand. I also make a full image of my laptop on an external drive more or less once a month to enable quick restore in case my OS gets hosed. One problem I still only semi-solved is synchronizing iPhones. Right now we just synchronize photos using Synology's DS File and I do an iTunes backup using a Windows VM which is clunky. High hopes for libimobiledevice here but I've had no time to properly research it yet.

All of the above requires some work but it's fun more than a nuisance. Probably not that great of a solution when I'm no longer around though.
