Google provides great cloud-based services, but it is important to keep a local copy of your data. This ensures that you have your data even if your account is compromised, Google has an outage, or data goes missing from your account.
CloudPull seamlessly backs up your Google account to your Mac. It supports Gmail, Google Contacts, Google Calendar, and Google Drive (formerly Docs). By default, the app backs up your accounts every hour and maintains old point-in-time snapshots of your accounts for 90 days.
