I am a restic user. Use it to backup to b2 and Scaleway. It is not without hiccups, but once setup, and as long as I don’t backup anything from those protected Mac folders, it has worked smooth so far.
However I also acutely feel the lack of a standalone GUI so that I can get rid of the scrips and custom setup or at
least that can be an option. (There’s a commercial third party UI I think which is a subscription)
Another tool I’m looking at closely is https://kopia.io. It comes with a UI by default (Electron I guess). Though its UI and logo has quite some work left.
I trialed restic, kopia and borg and ended up with kopia, backing up to backblaze + opportunistic external hdd. Costs me cents a month for tb+ between all our devices. Agreed on the kopia UI (and logo, was only thinking that the other day!), it's pretty basic .. but to be honest it's all you need. I use it on my family's machines as well, including wife and parents (same bblaze, dif HDDs), and it means they can pretty much manage it without me. I liked restic and probably would have ended up with it if there was a decent oss/stock UI. Borg was significantly slower on my machine for backup and restore.

https://vorta.borgbase.com (a third party qt GUI for borg backup) has been really awesome.
