Closing as this has been solved.

There is a problem when merging this addon in 9.0 branch, there is no auto_backup addons at all.
Can you review this?

Thanks all @lasley, @pedrobaeza, @lmignon

What the heck - that PR (#620) has no files changed in it anymore. I can guarantee that wasn't the case before though because #614 is based on it.

I'm not sure what happened here guys. I guess I can resubmit the PR, but what about all the commits that made it on but I guess are blank?

[antespi]

ok, @lasley, you can resumit the PR in order to see if that fix it

[lasley]

What about the 54 commits already on 9.0 branch that are seemingly empty?

Closing, this was resolved in #636
