Deduplication information

You can view the amount of disk space saved by deduplication in the Deduplication Savings area:

Space Savings
The total amount of physical disk space saved by deduplication, including protection overhead and metadata. For example, if you have three identical files that are all 5 GB, the estimated physical saving would be greater than 10 GB, because deduplication saved space that would have been occupied by file metadata and protection overhead.
Deduplicated data
The amount of space on the cluster occupied by directories that were deduplicated.
Other data
The amount of space on the cluster occupied by directories that were not deduplicated.
