We know that Facebook has an option from which you can download your Facebook Data to your computer. This is very useful tool for those who need to have their personal Data on their PC Hard Drive.
Google has a similar service called the Google Takeaway, which lets you Download your Google Data on your PC Hard Drive. Just log in to www.google.com/takeaway & you can get all your data from Google Docs, Picasa Web Album etc.
It is very important to have a copy of your data by your side as it can help your gain lost data in case your account is hacked or that your personal identity is stolen. It is even more helpful if you want your pictures or photos in case you have deleted them from your Hard Disk or pen drive.
So enjoy this service!!!
