We will need information about how to back up, save, export, and verify the contents of a backup. This will help immensely with the usability of GnuPG, especially for its use with its target audience of developers that need to sign their GnuPG releases.
I'm going to look into the ```--export-backup```, ```--export-options``` and ```--import-options``` flags and commands for GnuPG and see what I can puzzle out, along with export of the TrustDB, as my previous method of simply exporting the keys didn't capture everything, including local signatures and trust settings.
