I have two machines, but, one share I simply can't lose, the two machines are in different locations geographically (By a couple thousand miles) so unless a world war breaks out hopefully nothing will break in both locations at the same time.

 

However, my question:-

How do I keep this share in sync on both machines? So if I change something on machine A, it's updated on machine B and visa versa.

I would be interested in this as well. I have a friend that lives about 40 miles away and it would be nice to have a backup off site of the more important files. I wouldn't need the sync both ways as much as some type of automated backup of only files that have changed. Anyone have anything like this running?

You could do something really simple like leverage the dropbox plugin... otherwise, I'd do some sort of VPN setup combined with cron'ed rsync scripts.

See here for rsyncd info: http://lime-technology.com/forum/index.php?topic=13432.0

Rsync can definitely do the job but can be a bit tricky to setup. 

I use syncovery as it can also zip/encrypt on the fly.

I'm a big fan of rsync.

However you should probably set up ssh, set up port forwarding and filtering with your router and put rules in the /etc/hosts.deny /etc/hosts.allow file.

 

if you have ssh exposed on your router to the world, the world will be knocking on your door with automated attacks. So you want to be sure to have the port filtered to only the destinations you want to connect with.

 

With rsync you can rsync back and forth between machines automatically.
