Well, I compiled 2.5 (from a tar-ball, not from the code repository) and installed it and just ran a few backup tests to DVD media. The first incremental I ran wrote two partitions to the disk and ended just fine. The second (a full) however, failed to write the DVD due to the typical problem I've been seeing: JobId 3757: Volume BaculaDVDTwo0140 previously written, moving to end of data . JobId 3757: Error: Bacula cannot write on DVD Volume BaculaDVDTwo0140 because : The sizes do not match! Volume=1125393071 Catalog=286543567 JobId 3757: Marking Volume BaculaDVDTwo0140 in Error in Catalog. JobId 3757: Please mount Volume BaculaDVDTwo0124 or label Note... The Volume size is correct, not the catalog. IE, the DVD writing process has succeeded just fine and the two parts from the first backup job are on the disk and are the right size (I know because I lightly hacked the dvd-handler to keep the older ones around for a bit). The catalog, however, seems to have the wrong notion of what the proper size should be.

Current Bacula does not support DVD any more, and the DVD code in it will propably get removed in some future release. so dvd support started for a while and now it is being removed again?? I use older version 2.0.2, and that seems to work ok. 2.4.2 does not work. Neither does 2.2.8. You propably have to relabel those empty discs, as the label file size should be 202 bytes. Bacula DVD documentation gives the needed commands to blank the disc so that you can label them again. they are 202 bytes, that's the size that bacula dir reports when i try to use those, but the problem is bscan doesn't recognize them as 202, thats what creates the size mismatch even after i try to fix the catalog with bscan 2) after trying lots of things i manage to burn a disk but when it asked for the second disk (which is actually part #1, it looks like bacula burns from last to first??) I have not seen this kind of behaviour in 2.0.2 version. finally, if i were to backup to a file and then write a script to burn the files, what problems would i encounter? when i used dar to backup, the biggest problem i had with this method was that the catalog pointed to those tmp files in the hard drive but they were actually in the dvd so the wrong paths made me have to manually update every dvd backup's path in the database. will bacula do the same? (i.e. store in the catalog some path to a backup that would get screwed if i moved the backups from temporary dirs to dvds). other problems were not the whole backup being accessible at once (since you have to change disks) and controlling when to use new disks (so if a disk has only 400MB free it should create a first 400MB file and then 4.5GB subsequent files for the rest of the backup). All this was very annoying since i had to code it all in a bash script. This was the main reason to switch to bacula, that it natively supported dvds.

Re: [Bacula-users] dvd problems
Who ( in the familly of admins ) could work with 4.5Go Media (even with 20Go blue-Ray ) We normally work with very big volumes, some hundred Go to thousand To. I actually used bacula-2.4.X and dvd media at work to backup an openvz guest and move that to home so that I could place it on the outside of a firewall (too difficult/expensive at work to get machines in the DMZ). However with that said I have 20+ TB of tape backups here at work making DVD media not a real option. At home it is dvd becoming less useful since the price reduction in hard drives ( I mean 1.5TB for $130 USA Wow) .

[Bacula-users] dvd problems
Hey guys i've been using bacula for some time to do file backups with no problems. Now i am trying to do dvd backups and i've been making nice coasters. i basically have 2 separate problems and fixing either of them would be good, both would be perfect. i followed both dvd tutorials available and trying to find previous messages on the list but searching isn't that easy. Anyway, here is my first problem. i'm using ubuntu 2.6.24 and bacula 2.2.8 1) i labeled 2 disks the same (this was actually very confusing, after labeling the disk bacula still was asking for a disk to be labeled, it didn't say anything about it being the second disk) and when the backup process failed before burning the actual data the disks became unusable, i tried fixing the volBytes entry using bscan and making the volume appendable but bscan seemed to be creating a wrong entry by like 20 bytes so bacula still complained about sizes mismatch. How can i use those disks that are still almost new just labeled but with nothing in them?? 2) after trying lots of things i manage to burn a disk but when it asked for the second disk (which is actually part #1, it looks like bacula burns from last to first??) i made a mistake and stopped the process, so now i have a disk with the complete and valid second part of the backup. Is there a way to resume the process using that disk that already has everything from disk #2 in it?? this is the current status of my catalog +-++---+-+---+--+--+-+--+---+---+-+ | MediaId | VolumeName | VolStatus | Enabled | VolBytes | VolFiles | VolRetention | Recycle | Slot | InChanger | MediaType | LastWritten | +-++---+-+---+--+--+-+--+---+---+-+ | 8 | mazinger-backup002 | Full | 1 | 4,680,732,370 |1 | 31,536,000 | 1 |0 | 0 | DVD | 2008-12-27 02:32:39 | | 10 | mazinger-backup| Append| 1 | 184 |0 | 31,536,000 | 0 |0 | 0 | DVD | 2008-12-26 18:01:16 | +-++---+-+---+--+--+-+--+---+---+-+ i upgraded today to bacula 2.4.2 but won't be trying anything in hope for some feedback.
