Copying a large file from an USB 3 disk (NTFS or EXT4) to another one (UFS/FreeBSD) is a very slow process....
ok. I know how to resume a transfer with rsync,but I don't know how to do that using cp. Which parameter should I use? 10x. On the next file I will use cp and I'm curious to compare both the speeds.
