Sorry, CloudPull has no ability to restore directly to Google. My emphasis has been restoring to local apps. In all cases, there are ways of importing back into Google, but none that the app does on its own.
The ability to restore directly to Google is on my roadmap for future versions.
No, CloudPull does not restore directly back to Google. You could do this independently by restoring to Apple Mail, and then importing into Gmail or another IMAP account.
My Mac app, CloudPull, does something similar. CloudPull backs up Google Mail, Contacts, Calendars, Drive (formery Docs) and Reader to your Mac. http://www.goldenhillsoftware.com/
CloudPull stores your password securely in the Mac OS X keychain.
