Netcat + XZ or gzip + CPIO or tar.

nc otherhost portnumber | xz -d | cpio -idm
find pathname -print | cpio -o -Hnewc | xz -1 | nc -l portnumber

Then rsync to reconcile.

If on a dedicated partition, consider a block-based tool that won't
need to traverse the filesystem
directory structure and won't need to copy unused disk blocks, e.g. partimage.
