A monolithic sparse image would have to be compacted and shrunk in order for a “gap” in the image’s file system to result in a “gap” in the host file system. This kind of compacting operation is very expensive to do over the network as it requires rewriting large portions of the image file. Generally, moving files around in the image is more efficient in a sparse bundle because you can logically re-order and delete stripes without actually re-writing them. If the disk is local, this isn’t such a big deal, but over a network it makes a big difference.

I don’t understand it. I’d expect more from a EFI’ed GUID’d fs that supports an LVM,
Why don’t they just LVM their home directories like the rest of the UNIX world?
I’m feeling a bit of vertigo seeing these sparsebundles as striped file based/block based backups. Why couldn’t they just do a block based backup to begin with?
