+The ratio of the total amount of storage that would be required to store all

+.It Sy dedupsaved
+The amount of additional storage that would be required if deduplication

+This represents the space saved by deduplication.

+The amount of storage used by deduplicated blocks.

Amount of uninitialized space within the pool or device that can be used to
increase the total capacity of the pool.
