Sure, if you ignore my last line saying it's easy to have 2-3 copies.
> For proper archival, each project gets its own backup device not shared with other projects
"its own backup device" implies only 1 copy? That's so much worse than 3 copies on shared drives.
And who isn't using shared drives? Companies use shared drives. Amazon uses shared drives. And you could double it to 6 copies for ridiculous levels of reliability and it would still be under $10 per shoot.
And if that's twisting intent, then you twisted mine much harder with "500 shoots die with it", because I explicitly suggested multiple copies instead of just treating it as assumed. What's with this one-sided accusation?
And if you're buying three drives per client that's an extra $200 per photoshoot in this scenario if we're talking hard drives. It's a massive cost. And it would need to be hard drives, since the client certainly can't read tapes, probably can't read a bluray, and a USB stick wouldn't be reliable unplugged. Also the idea of handing over a whole drive depends on them having a full license to every file you're archiving. For a photoshoot it's just not worth it in comparison to copying their deliverables folder out of the shared vault.
Edit: I guess you could go with stacks and stacks of blurays and be ready to hand out a drive every time you hand a disc out.
