Google Backup and Sync is downloadable software that allows users to take data stored on their Mac or PC — such as documents, photos, videos, etc. — and systematically sync them to their Google Drive account in the cloud.
Backup and Sync was introduced in July of 2017 as a replacement for the Google Drive desktop client, which has since been discontinued. The application primarily serves to make synced data remotely accessible while safeguarding from hardware failure and risks associated with physical data storage.
