Use rsync instead:
rsync -aHe ssh /home/ X.X.X.X:/home
The 'a' option means archive mode and does a recursive copy that
preserves times, permissions and (if root) owner/group info. The 'H'
option preserves hard-links and the 'e ssh' tells it to transfer over
ssh. The trailing slash on the '/home/' means to copy the contents of
the local /home directory. 'X.X.X.X:/home' is the destination of /home
on host X.X.X.X.
You can add the 'v' (verbose) option to watch the names scroll by and
the 'P' to see transfer progress of each file if you're using a slow
link. The 'c' option will run 'MD4' checksums at each end to increase
the robustness of the copy.
If you add additional options, make sure that the 'e' option is last:
rsync -avcPHe ssh /home/ X.X.X.X:/home
You can interrupt the transfer and rerun it using the same command. It
will resume at the correct point and continue.
