My idea was to minimize the amount of data I send to ibiblio each time I update. The trouble is, I have noticed that two particular folders always copy along with ALL their contents, even though they have not been updated for quite a while, and then I noticed that the local and remote file sizes for all my files are different by a random number of bytes for each file, sometimes as much as 200 bytes different, other timers only a few bytes.
Have I misunderstood something here? Why are the file sizes different, and what is the defined behavior of "keep remote directory up to date"???
