CCC vs. Finder for copying large directories
I'm wondering what the pros and cons are to using an app like Carbon Copy Cloner to copy large directories from one drive to another (in this case both USB driven external hard drives). I'm not now thinking of cloning a bootable drive/partition (I've done that too), but only copying large batches of files (images or music files).
Advantages seem to me that you can save tasks and repeat them; that if changes are made from the source CCC will only add the incremental changes (the finder might not know this but I suppose you could check off the box that asks if a file exists on the destination don't copy it, for all such files). I don't know that CCC does checksums and the like or that the Finder doesn't do this.
I can't think of disadvantages. I don't imagine either method is faster the first time around.
Thanks in advance.
