When someone says something is the "holy grail of backups" and it is "gpg-encrypted" I assume it does that well, not it does it poorly right now but might improve in the near future.

Thus his post was valuable to me.

"Why not add a PR" is not a reasonable response to something like this. I'm looking to use a backup system, not create one. If something works so poorly that I'd have to start submitting PRs before using it, I'm far more inclined to go elsewhere.
