Q:

Google Docs: How to backup periodically?

How do I periodically backup my entire online documents in Google Docs? I am looking for a tool that can download the documents to my PC. I do not need any kind of two-way synchronization, just plain one-way backup.
(I am using Windows. Feel free to suggest options for other OSes too.)

This was covered on Lifehacker:
Back up your Google Apps data

If you've jumped on the online word
  processing and spreadsheets bandwagon,
  you've probably already got a lot of
  docs on Google's servers (I know I
  do). By default, backing up those
  files means you'd need to download
  them one at a time, which is quite
  frankly a tedious waste of time.
Instead, Firefox users can back up all
  or select chunks of Google Docs and
  Spreadsheet files in various formats
  (including MS Office or Open Office
  formats, PDF, plain text, or CSV) in
  one fell swoop using the Google Docs
  Download Greasemonkey script. This
  solution requires a little diligence
  on your part (you'll need to regularly
  back up the docs yourself), but the
  Google Docs Download script makes the
  process fairly painless.

I found GDocBackup and it is working quite well for my purposes right now.
Thanks to everyone who suggested other options.
