We have an application which originally ran on one web server. Now we
are running several in a round-robin style. Of course promotions are
a growing problem.

Where can I begin to learn about mirroring or other methods of
maintaining several servers with the same code?

thanks

The two commands you should look at are 'rdist' and 'rsync'.

rdist has a control file, not unlike a makefile, and can execute
commands on the remote machines after file have been transfered. This
can be useful if you need to do things like populate databases.

rsync has the ability to only transfer the parts of files that have
changed.

thanks Icarus. rsync is perfect.
