Instead of beating your brains out writing scripts to do this, simply
install ports/net/rsync. Then synchronizing the file systems on the
two boxes is simple. From the machine with the original copy of the
data:
rsync -avx --delete /path/to/data/dir/ other.machine.com:/path/to/data/dir/
This will copy the data from the original filesystem to the second one
using the minimum amount of network traffic possible.
Nb. the trailing slashes on those paths are important.
Cheers,
Matthew
