I think It's very easy to do what you said using the hotplug facility 
and simple bash scripting. I've a system in one server that when you 
plug the USB disk, it mounts the disk, make a rsync which certain 
directories of the local file system, umount the drive, and send a email 
which logfile (you can use a wall if you prefere). Now I'm working in a 
system based on these and LVM, to take snapshots of live filesystems 
using wonderful facility provided by LVM that is snapshots.

If you want to know more, feel free to ask me.
