I think the only way to do it at a reasonable speed is to unmount the
partition where the archive is stored and image-copy it to an
equal-sized partition. Or, if you created it as a RAID1 with a missing
mirror, you can add/sync a mirror while mounted - but you still won't
have any performance if you try to do anything else for the duration of
the copy and you need to unmount momentarily to get a clean filesystem
as you fail/remove the mirror.
Some people are copying smaller archives with rsync (-aH), and the
newest version of rsync is supposed to handle the hardlinks more
efficiently. You can always try that and see how long it takes.
