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?
