I've setup a backup site on InsaneJournal. Since I didn't have to contend with someone who hasn't posted in years having my preferred username, I am there at http://rono.insanejournal.com, or with the user name of "rono."
I've been running the python software that johnridley mentioned. I haven't confirmed that it has transferred everything, but once I do I'll probably put it into a cron task and have it run a couple times a day.
