Release: 2.0.4.21 (experimental) 2019-06-28 was just announced, so canary now has some ability to diverge as experimental turns into beta sometime soon (we hope). If you stay on canary too long, you might pick up a newly added bug, or a DB format update that impedes return to beta (which you may or may not intend to do).
Plus, as much as canary testers are needed, testers for experimental are the last line of testing before beta…
Regardless, I hope your restore and continued backups go well.
