I think DRBD (http://www.drbd.org/) should able to do that at the
block device level.

I searched for such solution myself a few years ago (search for a
thread named "Live website mirroring" or something similar in the
archive) but meanwhile settled for hourly rsync job and never really
tested DRBD.

Another solution may be putting the data in a database with
replication support, if possible in your environment, especially if it
really constantly changes.

You can probably find more related information in the Linux-HA
website: http://www.linux-ha.org/
