I Cannot Determine How Much Space is Saved Using Complete Single Instance Storage

Valid on all Exchange Server systems.

Symptom

After I back up data using Single Instance Storage, I cannot determine how much space is saved.

Solution

After you submit your backup job, you can go to the Job Status Manager and double-click the active job to view real-time job properties. If you have Complete Messaging Single Instance Storage enabled, all of the fields related to size will reflect the size prior to single instance storage optimization. The actual size of the backup after single instance storage optimization opens in the Activity Log and is labeled “(xx)MB Written to Media."
