Any suggestions for file sync tools? I have some Windows boxes with folders that have several real enormous files. Some data is appended to the end of these files daily. I'd like the sync software to be smart enough to transmit just the changes at the end of the files rather than sending the entire 100+ MB files over each time.
I would imagine someone else out there already thought of this and coded something to perform this function. It seems to me that a multiple checksums could be compared on files in, say, 64k blocks, and when mismatches are found, those blocks coul be transmitted.
I'd rather not write this myself. Any ideas?
