An EMC NetWorker customer is planning on directing the backups of a database server to
the single-engine EMC Disk Library (EDL) as shown in the exhibit. The data to be backed
up is accessed by the host through a redundant connection and resides on primary storage.
Based on EMC best practice, what needs to be adjusted in the solution?

A customer is interested in implementing two DL4000 systems. One system is located at a
central site. The second is at a remote site as a target for Remote Copy operations. Policies
will be configured to replicate certain tapes to the target. Which process is necessary to
make the virtual tapes available on the target?

A potential EMC customer has a T1 circuit between their production data center and their
disaster recovery data center that are 2,000 miles apart. They currently back up their Linux
systems to physical tape using HP Data Protector. They back up an average of 20 TB each
night. The customer wants a backup solution that improves backup and restore reliability,
reduces overall costs, and eliminates physical tape. What is a recommended solution?

A customer uses EMC NetWorker on HP-UX to back up 20 TB per day to physical tape.
They currently restore 10 TB of database data twice a week. The customer needs a new
backup solution that will reduce backup and restore times and is highly available. What is a
recommended EMC solution?

A customer is interested in using a Remote Copy policy to replicate data between two
singleengine EMC Disk Library (EDL) systems. The customer is concerned about the
readiness of replicated tapes in case of a failure on the source system. What can be done to
minimize the exposure on the target?

An EMC customer is evaluating a single-engine EMC Disk Library (EDL) system. They
placed the EDL on their test infrastructure and performed 15 simultaneous backup jobs. The
customer is concerned that the overall performance numbers are substantially lower than
the published numbers. Each job is sent to a separate virtual tape at an average rate of 18
MB/s. The EDL is connected to the SAN through two FC ports at 4 GB/s. There are a total
of 15 LUNs for virtual tape storage. The infrastructure has been certified to sustain
performance in excess of the EDL’s capability. What would you recommend to improve the
overall performance?

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?
