You say that it mounts the filesystem ok but that there is nothing in there?

It may be that there is a problem is that script. > Can anyone with a working DVD setup point out what I'm doing wrong?

Sure take a look at http://bridge.oldelvet.org.uk/bacula/BaculaDVDSetup.html Before you go much further there are a couple of things that I can think of: 1 - try ejecting the DVD and reloading it. Linux has a "feature" that it doesn't rescan the block device after a write to the DVD. It may be that the mount cannot see the data that has been written. An eject forces things to get rescanned. 2 - One thing that is missing from your config is MaximumPartSize = 800M; that limits how big each entry (part) written to the DVD is. I don't remember what happens if it is missing but it may be that it will just fill as much as the DVD will take. Hence your first (and second) dvd volumes may have been written without the need to mount the drive to check space and hence bacula didn't notice a problem.
