A customer 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?

A.
Clients have deduplication references to the same data

B.
Data Domain retention lock is active

C.
NetWorker clean process was not run

D.
NetWorker Data Domain device has automatic retention set
