I'm trying to get Apple's Time Machine to back up to a TrueCrypt encrypted partition and failing horribly. I was able to get Time Machine to at least acknowledge my TrueCrypt partition by typing the following in
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
but when I select my TrueCrypt volume, nothing happens. Or more to the point, Time Machine doesn't actually start using that partition. If anyone has ever gotten this to work I'd really like to hear about your experiences. I realize I could just use file-vault, but I'd really perfer to use full hard disk encryption instead.
