    Rsync files that do not exist on drive b from a to c

    The title pretty much says it all. I have 3 drives, a,b,c. Drive a has all of the data that b has, as well as some unique data. I need to copy the unique data from a to c.
    Any ideas, and thanks in advance!

    I do not believe that rsync has a native feature to handle this. I'd suggest doing a dry-run (-n) rsync from a->b, which should create you a list of everything it *would* transfer. Then, use that list (most likely in a while-loop) to sync from a->c.
