The classic solution to this is rsync, which I find to be somewhat
tricky but can get by using grsync (a GUI version) to set up. rsync is
magic in that it only transfers differences. It does however take a
while each time it's run to find what's changed and I haven't found a
good way to skip that and say just push new stuff since I know the old
stuff hasn't changed. This could be set up as a cron job to just happen
in the background.

The other method I sometimes use for this challenge is version control.
I setup the master repository on my server and then use standard version
control methods to keep my 2 desktop/laptop machines up to date whenever
I get on them. There's a little extra work here since a user has to
manually say "add" to the version control system then push the files,
and remember to pull/update on the other machine. Some of the common
version control system do have integration with Nautilus or Dolphin (The
file managers) so you don't have to learn command line.
