Thanks, Ioa. That sounds great, but are you sure the sparse image is a bundled format? I was under the impression that a .sparse image is one giant file, while the .sparsebundle image is a package.
Either way, I don’t need to use a sparse image at the moment — I’m only using a tiny image and at this scale sparse seems to use more overhead space than a regular image. That’s not an issue for DropBox with its binary diff method of syncing, but it might be an issue for Time Machine. BTW, I do use Time Machine (and Crashplan), plus DropBox keeps recent versions up to 30 days, I think. And those are all automated backups, so backing up doesn’t impact the workflow at all… I love technology.
