I have a locally stored disk image. I would like to mount this, but have macosx think it is shared over a network (a network shared volume).
I want to do this because TimeMachine would then effectively allow me to back up to this disk image.
I tried sharing the locally mounted volume using afp, but found that macosx prevents me from mounting the volume locally since it sees that i could just access it directly.
Ideally the network share would only be accessible over the loopback interface, to prevent security issues.
