Aperture Vault size
The big difference us that the vault does not store the cached thumbnails.
My vault is only 75% of the size of the library. If restore from the vault, my library takes on the smaller size of the vault. Then as I use it, the thumbnails are rebuilt and it grows again.
I'll post some articles on the vault when I get some time.
