To backup the passwords a copy of ~/.password-store/ is enough, but to completely recover, a backup of the gpg keys is also required. What's your strategy for this? Do you just backup the entire ~/.gnupg/ directory?
I use passphrase2pgp[1] so I can recreate my GPG key anywhere. I need to remember three pieces of information:
- passphrase (long sentence, but it's easy to remember) - uid (Name - easy) - timestamp (10 digits - kinda hard to memorize but you can have it noted is plain text since it's not sensitive information)
