I have both the sparsebundle size and the ZFS FS set. So the FS was created with a quota of 300GB and the sparsebundle then created in there with 300GB.
Unless you're backing up multiple Macs, don't use dedup, the performance hit you'll take will be huge after a few months unless you've got an obscene amount of RAM, like 64+GB. Dedup and compression give you more free space, and that's what time machine sees. Works great for me. I'm backing up 5 macs.
