About:
GyB (Got Your Back) is a command-line interface tool for backing up and restoring Gmail messages. It securely stores emails as standard MBOX files and can restore them to the same or a different Gmail account. This provides a reliable, open-source solution for email archival and migration without relying on Google's proprietary export tools.
Key Features:
  • Backup and restore Gmail messages to/from MBOX files
  • Support for incremental backups to save bandwidth and time
  • Preserves labels and message metadata
  • OAuth 2.0 authentication for secure access
Use Cases:
  • Creating regular backups of critical Gmail accounts
  • Migrating emails from one Gmail account to another
  • Restoring emails after accidental deletion or data loss
Alternatives:
  • Google Takeout – Official tool but not designed for incremental backups or easy restoration.
  • offlineimap – General-purpose IMAP sync tool, less specialized for Gmail's unique features like labels.
