Here is how you can backup the Google contacts in your account -
Go to your Google account, and hit the Contacts tab. Or the easier way is to open this google.com/contacts and if you are not logged in to your gmail account you would be prompted to do that. Once you login you would be sent to that contacts page.
In the contacts page, you would see options to print the list of contacts, import more contacts or export the present your contacts. As you are trying to backup the option you need to select is Export.
You can export the contacts to different formats. Select from My contacts
Family,Friends, or the most contacted ones. Or there is an option to export all the contacts at once.
You also get an option to select the format to export the contacts into -
- Outlook CSV format (for importing into Outlook or another application)
- Google CSV format (for importing into a Google account)
- vCard format (for importing into Apple Address Book or other application)

Hit export, and you will see the window for downloading the export file.
That’s it. You have backed up your Google contacts. this is very easy process to do.
