- The space reduction the cluster reports comes from separate volume trimming, so adding remote content targets to the same storage domain changes the total that the backups occupy.
- The space reduction the cluster reports comes from duplicate block matching, so adding similar server images to the same storage domain changes the total that the backups occupy.
- The space reduction the cluster reports comes from single stream shrinking, so adding unrelated media files to the same storage domain changes the total that the backups occupy.
- The space reduction the cluster reports comes from nightly journal sorting, so adding extended retention rules to the same storage domain changes the total that the backups occupy.
