@johnthagen You mentioned something about the functional tests on this repo being iffy. Do you think that might be the reason why the test_create_dump_with_newline in this PR doesn't appear to run (according to the codecov hits)?

Unrelated note, I confirmed at least one issue on Windows appears to be related to gpg support. See dbbackup/tests/utils/add_public_gpg.

I don't fully recall.

Maybe *nix specific tests like gpg could be marked as skipped on Windows: https://docs.pytest.org/en/7.1.x/how-to/skipping.html#skipping-test-functions

[Archmonger]

I'd need to confirm whether they should be skipped or not. It's very possible these tests failing is an indication that encryption support is broken on Windows.
