I can only go by my experience; a few years ago I saved a lot of Sonar HS6XL projects as .BUN files and burned them to DVDs for back up. Last year I went through those DVDs, and only about half opened successfully.

I think that's probably about the DVDs, not the bundle files. The lifespan of a writeable DVD-ROM is highly variable depending on how it was manufactured, whether it used organic dyes, storage, etc. As I've mentioned before, currently the most robust form of optical storage is Blu-Ray media using inorganic dyes.

Possibly, but there are several bundle files on each DVD, some will open, some won't. But no, I don't back up to disc anymore, for the reasons mentioned.

-Bundles can’t contain certain data such as AudioSnap and (V-Vocal I think) data. I’m not sure about any of the ARA data such as Melodyne, Drum Replacer or Vocal Sync.

you can test this by copying the BUNs off the DVD to HD before trying to open them - if the media is corrupt then windows will tell you

That's what I did, I never try and open projects directly from DVD. So, does that tell me the projects were corrupted by burning them and storing on DVD, or because some .BUN files are unstable?

i would suggest that the BUNs are faulting, but i could be wrong
i also seem to remember someone from cake (noel?) in the past recommended not using BUNs, rather the project-with-audio, but i could be wrong
i'll be going through a bunch of my old stuff soon, will post how i get on

Bun files are too risky. I just tried to open some old ones and a couple were corrupted and wouldn't work. Per project folders are much better way to archive projects.

were the corrupted ones stored on DVD? we're trying to figure out if it's BUNs or DVDs that are dodgy

Thanks everyone for the information and comments. 
 
So when you are done with your project you just select "Save" to save the .CWP to the project folder  and copy the project folder to your backup location to back it up?
