Summary

GMvault is a command-line tool for backing up Gmail accounts and restoring a local email repository to Gmail. It supports full synchronization and incremental quick synchronization, giving users two ways to keep a local copy of their correspondence current. The tool is free and open source under GNU-AGPL-3.0, with versions for Linux, macOS, and Windows. Its project documents binary installations for those systems, as well as installation from source with Python, pip, or easy_install. XOAuth is the recommended authentication method and is enabled by default; after the first sign-in, its token is stored in $HOME/.gmvault for later use. Users may instead authenticate with a Gmail login password, which can be encrypted if saved. Emails go by default to $HOME/gmvault-db, or %HOME%/gmvault-db on Windows. For restores, --resume and --restart options help avoid uploading messages that have already been processed. PyPI lists version 1.9.1 as the latest release, published March 31, 2016.
