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.
Drbd http://www.drbd.org/ does it live. If you can live with periodic snapshots instead, you can do it with rsync.
