Kern, I did not understand this as blaming bacula for it. Filesystems do fragment if they are getting full. And there is no real way around this. XFS tries to avoid fragmentation of files by something that is called "Delayed allocation" but XFS nevertheless ships a defragmentation tool with its fs-utils. (I do not know such a tool for ext2/3 btw) I think what the original poster tried to say is: Bacula could help in filesystems not getting too fragmented over time by not freeing its space used, but instead just overwrite it. This would definitly make much sense in some (if not all) environments as it would keep filesystem performnace at a high level. And to be honest: This has nothing to do with a "strange OS that is not state of the art" or you would call todays linux to be such an OS. Please think about it a second time...
