A private backup utility operated by The Lost Garage.
solaris-backup copies encrypted database backups from the owner's own server to the owner's own Google Drive. It is a single-user tool for personal and internal use. It is not a public service, and no one else can sign up for or use it.
The app requests only the Google Drive drive.file permission, which limits it to the files it creates itself. It cannot see or change any other files in the Drive.
