If you want block efficient, then zfs is your friend
1) make the 'dir' be a distinct zfs filestore in the zpool
2) run zfssnap on some duty cycle
seriously: as long as the copy can be maintained readonly, in sync
with the source, the block level copy of zfs snapshots under some
serial/time cycle, does the job.
I ran this over mbuffer to get around ssh insane packet behaviour, I
only stopped when the client wanted to prune the copy and it ceased to
be a zfs snapshot copy.
Its much faster than rsync. Its at the filesystem block level.
