I wonder how current Bacula users who have decided to back up to > optical DVD media have found it to be in terms of reliability?

And that cd/dvd media is also a very bad choice for archival because the media breaks down over time. Personally, I have not seen this happen with write once media as I have 10 year old cd-rs that still read fine however I have had difficulty reading RW media.
> Besides the low reliability concern, are there any other reasons to avoid > using optical DVD with Bacula other than what has been written in Chapter 24 > titled " DVD Volumes" of the current Bacula User's Guide? > I consider the DVD writing in bacula to be in a beta stage as backups can have problems writing/appending to the media. In the past I have had a few too many problems (and no time to debug) with this so I have not done any dvd backups in a long time.
