If you want a G Suite backup tool, then I have the best option for this because I'm also using a tool for it. You can try the GainTools G Suite Backup Tool, which provides users with a secure method to download Google Workspace data which they can proceed to save on their local devices and personal computers. It supports multiple backup formats, including PST, MBOX, EML, and MSG, while preserving email structure and attachments. The utility provides both complete and selective backup, making it flexible for diverse requirements. The software provides a user-friendly interface that allows non-technical users to operate the software without needing any technical skills. The application functions on every Windows operating system version from 11 to Windows 7 without needing any installation process.
