A customer has EMC NetWorker integrated with Data Domain. They noticed that they have incorrectly configured their NetWorker Browse and Retention policies for all currently defined clients. This issue was discovered when a DPA report was e-mailed showing the amount of available space on their EMC Data Domain system. The customer has made the necessary corrections to the Browse and Retention policies. They have manually deleted save sets that should have been expired based upon the new Browse and Retention times. After comparing the size of the index directory, prior to and after the modification, the customer noticed that the index directory decreased in size by several hundred GB. However, the available space on the Data Domain remained unchanged. Although NetWorker has deleted the necessary indexes, why does the Data Domain available capacity remain the same?
