A Symantec NetBackup customer is planning to add a second data center. They would like to

leverage deduplication technology to improve backup operations and disaster recovery with a
minimum amount of change to their existing backup environment. The customer’s primary design
goals are:
1. Improve backup performance
2. Electronic vaulting for disaster recovery
3. Maintain NetBackup as their primary tool for backup control and visibility
What should be included with a high-end Data Domain appliance?

A customer has two files that have been locked and backed up to the Data Domain appliance with
the following parameters:
• File1 = atime = 20 years
• File2 = atime = 5 years
The Data Domain global retention periods are configured as follows:
• Min = 2 years
• Max = 10 years
The administrator changes the Data Domain maximum retention period to 4 years. After how
many years can File2 be deleted?

A customer performs weekly full backups and daily incremental backups. A typical full backup is 5
TB. There is usually a 20% daily change rate in data. A full backup completes in 10 hours while an
incremental backup completes in 4 hours.
Based on best practices, what is the minimum Data Domain throughput required?

The EMC account team has been asked to design a NetWorker backup solution. The customer’s
environment consists of a Microsoft Exchange Server 2007 Cluster Continuous Replication (CCR)
deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library.
The customer wants to leverage the Microsoft VSS framework to back up their Exchange server
from the Exchange Server 2007 CCR passive node. What needs to be considered when designing
this backup solution?

An EMC NetWorker customer is considering implementing NetWorker AES encryption to secure
backups on one of their application servers.
What is a concern when using AES?

The EMC account team has been asked to design a new EMC NetWorker backup solution for
Microsoft Exchange Server 2007. The customer’s environment consists of Microsoft Exchange
Server 2007 hosted on an EMC CLARiiON disk array with EMC VSS Provider and an EMC Disk
Library.
Your design needs to include a server-less backup solution for the Microsoft Exchange Server
2007 environment by leveraging the Microsoft VSS framework. What is a recommended approach
to meet the customer’s requirements?

A customer has had a failure of the primary deduplication node and needs EMC NetWorker to
recover the data from the replication node.
What will enable recovery from the replication target node?

You are adding an Avamar deduplication node to a customer’s EMC NetWorker environment.
Clients currently back up to tape and perform full backups on Sunday and incrementals on all
other days.

In the new solution, these clients will back up to the deduplication node. The speed of recovery is
important to the customer. Which changes may be required to the backup schedule?

You are redesigning an EMC NetWorker customer’s backup solution. Currently some of the file
system clients are backing up to an Avamar deduplication node. The customer wants to back up
these clients to a new Avamar deduplication node.
What is an implication of this decision?

An EMC NetWorker customer performs daily full LAN backups of a busy application server to
physical tape. The application server uses the compressasm directive to reduce LAN backup
traffic. While the backup completes within the required backup window, the customer notices that
the application is performing poorly.
What can be done to improve application performance while maintaining minimum network traffic?
