I'm trying to see if zfs dedupe is effective on our datasets, but I'm having a hard time figuring out how to measure the space saved.
When I sent one backup set to the filesystem, the usage reported by "zfs list" and "zfs get used <my zfs>" are the expected values based on the data size. When I store a second copy, which should dedupe entirely, the zfs commands report the doubled used space that would be occupied if dedupe was turned off. My question is, are the numbers being reported by the zfs command taking into account the deduplication, or is there some other way to see how much space we're saving.
