You have been tasked with designing a backup solution using EMC NetWorker to backup a
VMware environment. The environment will be using virtual NetWorker proxies to perform
image-based backups. You will need to backup 36 virtual disks at a time in order to meet
the backup window. The ESX hosts used in this environment are low-end and have a small
amount of processing power. What is the recommended way to configure NetWorker
proxies to meet this design?

why does the Data Domain available capacity remain the same?

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?
