I use Pika Backup which runs on the BorgBackup protocol for backing up my system’s home directory. I’m not really sure if this is exactly what you’re talking about, though. It just sends backups to network shares.

I'm actively in the process of setting this up for my devices. What have you done for off-site backups? I know there are Borg specific cloud providers (rsync.net, borgbase, etc.). Or have you done something like rclone to an S3 provider?

No off-site backup for me, these items aren’t important enough, it’s more for “oops I broke my computer” or “set my new computer up faster” convenience.

Anything I really don’t want to lose is in a paid cloud service with a local backup sync over SMB to my TrueNAS box for some of the most important ones.

An exception is GitHub, I’m not paying for GitHub, but git kinda sorta backs itself up well enough for my purposes just by pulling/pushing code. If I get banned from GitHub or something I have all the local repos.
