Remote Tracking/Mirroring

Hi All,

I'm looking to set up some kind of remote tracking or mirroring of a
filesystem.  My thought was to write a mount-handler, mount the
filestore using that device type and have the handler simply pass
through all the transations to a normal ext3 filesystem underneath.
Then pass any write-type activies over a socket to a user-mode
program on another machine to mimic the action in the target filestore.

I didn't want to do a block-level mimic adn I did want to allow the
target filestore to be just an ordinary filestore, probably containing
other stuff, or having the target in just one part of a large volume.

Does this exist, or is anyone doing something like this ?  I want to
be able to have a 'hot' backup of one machine on another remote machine,
including all activity to date, up to the minute.

Jonathan
