Scenario
A customer is looking to perform a data center refresh. They want to standardize their backup
infrastructure by using EMC NetWorker, Avamar, and Data Domain in an integrated environment.
The environment consists of:
A primary data center – NetWorker server, Data Domain, and Avamar
A disaster recovery (DR) data center – Data Domain only
220 remote sites
Each remote site consists of approximately 30 clients and 1 storage node
LAN speed at and between all sites is 1 Gb
The company’s Chief Technology Officer (CTO) has indicated that data must be backed up locally.
Then, the data must be copied offsite to the primary data center and DR data center. The entire
solution must be managed from a single unified interface in order to configure and track backup
jobs.
The company is subject to government regulations concerning data retention policies for
confidential data. Data has to be retained for seven years on tape at the DR data center.
The LAN administrator has indicated that the least amount of traffic should traverse the network.
Based upon this requirement, what is the recommended solution?

A.
Client Direct to Data Domain

B.
Client Direct to Avamar

C.
Traditional backup

D.
VADP backup using NBD transport mode
