Looks like a complicated way to do what a simple 'scp -pr source target'
will accomplish.  Or am I missing something?

Rodrick does have a point, though: if you simply want to copy new files from
server A to server B, a simple copy will be faster than rsync, as you don't
need the comparison phase.  But scp will be faster than the tar - transfer -
untar.

Kind regards,
