I also use restic for backups. I actually switched from Borg because it kept getting stuck and failing but couldn’t work out why. Not had issues with restic (so far, touch wood!).

I use resticprofile with yaml configurations though (https://github.com/creativeprojects/resticprofile), which made it much easier for me to figure out.

I use borgbase for offsite backups.

They really push you to install the aio container so it’s not surprising to me.
