I don't know if this was the fault, but my home-brew Time Capsule setup has been failing lately, and this weekend I probably put in 5+ hours of mucking around to try to get it working, and then it'd work, go for a few (1-20) Gb, and then fail. Looks like this might have been caused by the Mozy backup, which has been fixed. Fingers crossed that I can get this set up and working tonight with the updated Mozy software!
