Trying to backup the contents of a 2 TB external drive to another of equal capacity. Finder copying is extremely slow. Is there a quicker alternative?
I would recommend using rsync for this:
rsync -avP /disk1/ /disk2
/disk2 are the mount points of your two disks. The
-a flag will keep file metadata intact and
-vP will give you a verbose progress indicator.
Main advantage is that you can stop the process at any time and continue later simply by running the same command again.
