Backup Facebook with Archive Facebook
Well, since that was a paid app and people mostly prefer free tools and applications, I’ve found a free method to backup your Facebook profile.
ArchiveFacebook is a free tool that allows you to save content from your Facebook account directly to your hard drive. Archive your photos, messages, activity stream, friends list, notes, events and groups.
It is a Firefox extension, which helps you to save web pages from Facebook and easily manage them. Save content from Facebook directly to your hard drive and view them exactly the same way you currently view them on Facebook.
The addon is still in experimental stage, so you will need to create an account at the Firefox addon website.
You can download it from here: Download ArchiveFacebook
