Doing some quick Googling about, it seems that CBZ provides a better reading experience, but for long-haul archiving, I'm concerned it may be a more transitory format than PDF.
I don't have any specific plans to be constantly reading the backup files, but I don't know if there are other significant trade-offs between the formats.
Any other thoughts on advantages or disadvantages to consider?
Whoa, you can make back ups now? That is a huge change. I may have to re-consider digital then.
I find pdf to be the best, just because so many platforms use it
+Brian Romano Yes, but only for selected publishers and not the Big Two.
@Dave CBZ is basically a renamed Zip file, and I prefer that format. I think Zip files will be around for a long time.
A CBZ file is nothing more than a zip file full of JPGs with the file extension changed, but it is way smaller in size for the same quality. PDF offer zero advantage, none. Get the CBZ format and enjoy.
+Franklin Morrison Only for publishers who approve, that is. So, yeah, that leaves out DC and Marvel at the moment. Will they hold out indefinitely? No idea. But it's a start.
+Scott Jordan Well, a test download of Saga #21 showed a 1% difference (300K out of 31000K), so size isn't that big of an issue, it seems.

Hmm, too bad, but thanks for the info.
+Brian Romano It is too bad. Current participants include Image Comics, Dynamite, Zenescope, MonkeyBrain, Thrillbent, and Top Shelf, though, so that's non-trivial.
+Dave Hill It will depend on the compression and image settings used. I am not sure how they are doing it. When you have a few tens of thousands of comics, it adds up quickly. I average much larger size differences, though.
However, another factor is that ZIP is much easier to manipulate, like if you want to delete the ad pages.
+Scott Jordan I don't suspect I'll be curating them that carefully. 🙂
