We've seen unusual behavior with QNAP NAS devices, which do not properly support sparse bundles (that's why you weren't able to make one to the QNAP directly). Please change to using a sparse image.

(It seems that when an alias is resolved to the file on a QNAP NAS, it can sometimes resolve to a totally different file, which is weird and bad. We've had one or two other users find the same thing, always to QNAPs.)
