I have to say I noticed, the forum is quite empty and the slack has many questions not answered, many doubts I have I did find already posted threads unanswered and not reported in the docs (for instance this), little doubs, the big ones you were very kind to answer but without your replies I would have stopped at the first important non-answered doubt.
We also have to say there are few alternatives, kopia is the fastest and has a ton of features, restic is not so rich of features, duplicati is not so trusted and duplicacy seems to be the new de facto standard? Really there are so few options in backup frontends I would not even know which alternative to consider
