Happy New Year!
Do you trust Facebook to keep all of your data - all of you photos, chats, posts? What happens if there is a cyber attack on Facebook that wipes it all out. Will you be OK with that? Maybe its time to download a copy of your Facebook data.
Its easy to do. Just click the down arrow on Facebook's tool bar and choose Settings.
That will take you to your Account Settings. At the bottom of the General Account Settings, click the link to "Download a copy of your Facebook data."
It will ask you to confirm your password, and then it will put together a Zip file of your data that you can download. Easy peasy.
