If you want an exact copy and are going to the same sized drive or larger, one
of the handiest ways is to boot a clonezilla-live cd and let it do a disk-disk
copy. It knows enough about most file systems to only copy the used disk blocks
but otherwise it is an exact image copy.
Otherwise, 'rsync --one-file-system -aH source target' will work and will pick
up where it left off it you stop and restart. I usually cd into the source
directory and use '.' as the source to avoid having to remember whether the
directory name will be created on the target or not. /dev and /proc are mount
points best skipped with the --one-file-system option.
