FYI, I've been doing it for 2 years or so; once it was up and running it works fairly well. I do save the parts to a separate folder after writing them to the DVD just to make sure, but most of the time they just get deleted. Occasionally an older disk will fail to burn properly and I either need to hard-burn the parts (again) to the disk or simply mark the disk as bad in the pool and let bacula recover based on that knowledge. a I'm not confident about using removable usb disk because it's not a a safe made media.

That being said, external disks are still more than a stack of DVDs. Eventually you'll spend as much as an external disk though. DVDs don't handle writing to them a huge number of times, so eventually they go bad and need to be thrown away (eventually just from scratches, no matter *how* careful I try to be).

I constantly think to myself wow, bacula is really cool; but why isn't it doing that? The configuration is complex to set up (but with flexibility always comes complexity; and bacula is very flexible). Fortunately there are many good resources to look at, but sorting through them all to find what you want is sometimes difficult. Personally, I've been using it for 2 months. On day one I got it up and running and backing up multiple computers (windows and linux both). But, I've still had issues with it backing up files I didn't want it to (no doubt my fault), failing to write DVDs properly (questionable fault, but I think I've fixed that through a patch to the dvd-handler), failing to recycle volumes that I believe it should (no doubt my fault). But even after all that, the flexibility is very necessary for me and I'm going to keep plugging away at it (just yesterday I had to re-learn that volume longevity for previously created volumes is in the DB, not relearned from a modified config. Which makes sense, but when you're editing the config it's easy to forget). So, let me say: thanks to all the developers of bacula. I know what it's like to run an OSS project and get yelled at (I've started a number at this point). Realize that the vast majority of your users are very happy with your work (myself included). Kudos to you all for your time and even more importantly: your patience in helping us through problems. Outstanding support!

Something to consider (or ignore) at will... Now, the down side is that the questions didn't stop. They just got harder. If you remove the easier-to-understand problems users start asking questions about the harder areas of a project because they get farther ;-) Final word: I love bacula and wouldn't switch away from it if I had a choice.

[Bacula-users] missing part on a DVD... why? what to do?
I've just recently been playing with bacula (2.0.3 in self-compiled rpms on fedora)... I have it working with DVDs and the situation in question as I can tell went like this: - it was backing up the main system. - I believe it tried to store the information in: BaculaDVD0009.8. - However, the disc doesn't actually contain that part, but the log shows success: 12-Jun 23:05 machine-sd: Ready to append to end of Volume BaculaDVD0009 part=8 size=3040970041 12-Jun 23:05 machine-sd: Job write elapsed time = 00:00:04, Transfer rate = 57.92 K bytes/second 12-Jun 23:05 machine-sd: Part 8 (233000 bytes) written to DVD.

I doubt anyone can answer this. the disc is not full yet and mounting it shows about 3G in use: /dev/hda 2972194 2972194 0 100% /mnt/cdrom and the missing part was very small: FD Bytes Written: 228,657 (228.6 KB) SD Bytes Written: 231,716 (231.7 KB) 2) what to do about it? Choices are, I think: 2a) invalidate the whole volume 2b) somehow tell bacula that just that part is missing and to rewrite just that part... I can't find anywhere that the part number is actually stored though. I did a quick search of even the DB tables and came up blank. I don't believe this is user-editable data (which is fine). 3) how do I prevent this in the future? Doubt anyone can answer this either, since it would require answering (1) above. (I turned on tracing on the sd to figure out this problem and it finally pointed out that the next backup was failing because it tried to mount the disc and couldn't find BaculaDVD0009.8...
