I have a friend who had their Gmail account hacked the other day and thought for a while they lost everything (contacts, archived emails, documents). After I felt bad for them, I realized how much stuff I had in my Google account that wasn’t anywhere else. It set me on a mission to find out how to backup my account, specifically my Google Documents, so I have another copy of my files on the computer and not just in the cloud.
There are lots of different ways to do this. While you can pay for some services that do it automatically, I think using google.com/takeout is your best bet for the money it costs — nothing.
This free service from Google not only lets you backup your documents (as can be seen in the video above), but you can also download a host of other information you have stored in Google from your contacts to your Picasa photos.
I have set a monthly reminder in my Google Calendar to alert me each month to download a backup of my Google Docs from Takeout each month. That way, if the unthinkable happens and my account is hacked or accidentally deleted, I will have most of my information.
