How to Download Your Information from Facebook
This was one feature that was always missing from Facebook. And there was no proper service either to backup your Facebook account (SocialSafe did pop up a while ago).
When this feature rolls out, it will be very easy to download/export your information from Facebook. All you have to do is, go to Account (top right menu) > Account Settings > Download Your information. Select the option to download a .zip file which will have your entire Facebook profile, including photos, videos, wall posts, messages, friends, notes and a lot more.
Currently, there is no option to restore or import this data back into Facebook, but I’m sure that feature will be coming out soon once the “Download Your Information” is rolled out for everyone on Facebook.
