If you are brave, you can also "cheat" - patch engine-backup to allow
recovering 4.1. That's a trivial patch, and the main problem with it
is that no-one tested it, and I do expect it might introduce subtle
issues. But considering the alternatives, it might be a reasonable
approach. If you do, try restoring first on an _isolated_ VM somewhere,
try to see how the engine behaves after restore (it will not work
very well, because it will not manage to access its hosts - if you
indeed isolated it well enough), and if it looks ok, try for real.

See also e.g.:

That said, not sure why 4.1 does not work for you. I think it should
still work, although I didn't try by myself recently.

Good luck and best regards,
