So, backing up LJ

Was on Twitter when I tripped over posts such as http://www.metafilter.com/164293/LiveJournal-represents-social-media-without-borders talking about US/Russian stuff and Live Journal.

I do need to back up LJ. Eons behind on that. I hear Dreamwidth is good, but is there a way to backup everything, post, photos AND comments that other folk make?

Thanks!
