Eternos

A while ago I posted about Lifestream backup which makes a backup of your online life at facebook, twitter, wordpress, photobucket, etc. (Seems they have been renamed to "backupify"). Another entry in this space is Eternos "

Eternos supports backup of Facebook, Twitter, Gmail, Picasa Web Albums, Blogs, and RSS feeds. You can see your posts in attractive timelines. One interesting twist they have is dealing with your data when you die: they let you designate trustees that will gain access to your account "upon confirmation you have passed on."
