Guillaume Aubert

Guillaume Aubert is an independent software author known for Gmvault, a lightweight yet comprehensive command-line and desktop utility engineered to create self-contained backups of entire Gmail accounts. Designed for privacy-conscious users, migration projects, and compliance archiving, the tool authenticates through Google’s secure OAuth layer, then incrementally downloads every message, label, attachment and chat into an open, compressed file tree that can be stored on any local disk, NAS or cloud bucket. Because the archive is rendered as standard MIME files accompanied by a JSON metadata index, it remains fully searchable with ordinary desktop tools and can be restored back to the original account or copied into a different Gmail address without duplicating messages. Scheduled sync options keep the mirror current, while TLS encryption and optional PGP signing protect the offline dataset. System administrators appreciate the headless mode for scripting nightly backups of organizational Google Workspace accounts, and individual users value the portability that lets them switch email providers or recover quickly from accidental deletions. The codebase is cross-platform, requiring only Python, so the same workflow runs identically on Windows, macOS and Linux. Guillaume Aubert’s Gmvault is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest release, and can be queued alongside other applications for unattended batch deployment.
