Backup and Sync will replace the current Google Drive uploader client for Mac/PC and will also be integrated into the desktop Google Photos uploader. Instead of creating entirely new folders on your system, the tool allows you to select system drives and folders and accordingly will recreate your system in the Drive. The tool will not immediately be available for G Suite Basic, Business, and Enterprise Customers. The new full-system backup tool is useless for free accounts that come with 15GB of storage, but users can get 100GB of. storage for $10/month, 10GB. of storage for just $2/month.
