dump/restore in a pipeline would be my choice, at least if you're copying 
ext2 or 3 filesystems. You can see an example in old copies of the restore 
man page:

<http://www.daemon-systems.org/man/restore.8.html>

dump 0f - /usr | (cd /mnt; restore xf -)

dump reads through the block device and restore writes through the 
filesystem. This will preserve holes in sparse files, because the holes can 
be detected in the raw filesystem format.

When dump is mentioned, someone inevitably mentions that Linus disapproves 
of dump:
