Hi @ciro.pappada,
Thanks for sharing.
The backup feature you see in the CLI a very, early-stage preview of backup. It kind of snuck into the CLI way back when we first released the odrive Agent. We didn’t remove it because there isn’t really any chance of “misusing” it and the fact that it is in the CLI lends itself to only being seen/used by more advanced users. Backup is a much simpler data flow, compared to sync, since all of the data flows in a single direction and there are no deletes/moves/etc, so you can’t really get into trouble using it.
I do want to stress that it should be viewed as a “beta”, at best.
