An EMC NetWorker backup environment has 300 clients distributed among three subnets. All
clients send their backup to the NetWorker server. The customer is experiencing poor
performance during backups.
Which modification to the existing environment will improve the backup performance at minimal
cost?

When performing an NDMP backup with EMC NetWorker, how is file history processed by the
