Bulk copy large blocks of data between File Systems (run as root iff you do not own all of the files!)

tar cpof - src |( cd des; tar xpof -)
Using tape archive create a tar file in Stdout (-) and pipe that into a compound command to extract the tar file from Stdin at the destination. This similar to "Copy via tar pipe ...", but copies across file systems boundaries. I prefer to use cp -pr for copying within the same file system.
