mesa-backup
mesa-backup is a small personal tool. It copies its owner's home-server configuration backups, encrypted before they leave the server, into the owner's own Google Drive.
The app has one user: its owner. It is not offered to anyone else, and it does not collect, share or sell anyone's data.
Access to Google Drive
mesa-backup asks for a single permission, the Google Drive drive.file scope. With it, the app can see and manage only the files and folders it created itself. It cannot read anything else in the owner's Drive.
