Lsyncd works great, when you know that your disks are stable and won't 
randomly disappear.

One option is, if you do this regularly, but don't need it to be updated 
up to the second, just write a script to rsync it via cron. You could 
run it at whatever interval you're ok with, be that once every 5 
minutes, or once a month or whatever. This would allow you to make sure 
that the disk is there, because if it's not, lsyncd will happily just 
write all the files to local disk under the mount point, just as you 
have already seen.

Another option here is to write a cron job that runs every 15 minutes or 
so, and looks for the mount. If it doesn't find it, you can have it 
email you. If it does find it, you can have it just exit.

Yet another option is to setup something like Nagios and monitor the 
disks with it.
