Use CloudPull ($10) from http://goldenhillsoftware.com and it's by far the best Google backup tool I've found. It supports Gmail, Google Contacts, Google Calendar, Google Drive/Docs, and Google Reader. The app backs up a max of 10 accounts in the background and all the data is available in standard file formats.
If you want true sync then use insync ($10/account) from https://www.insynchq.com. It gives you two-way sync of your Google Drive. You can edit your document in Office offline and it syncs to your Drive. It works very well.
