Anyone ever experienced using DRDB or some other distributed fs with linode ?

I already run a local backup of my server (data only, via rsync), but I'm willing to make my backup server handle everything if the first one dies.
Any experience on that ?

Thanks

Haven't tried DRDB or other stuff on the Linode, but FUSE and sshfs might be an interesting option?

I have tried FUSE/sshfs on the Linode, and works like a champ, though I would probably not ordinarily do that for major filesystems (/, /usr, /var, etc).
