Scenario
A customer with a fully virtualized environment has four ESX 4.1 servers in a cluster with a SAN
solution for storage. Each ESX server is hosting 40 virtual machines and all virtual machines have
the same local disk configurations:
Disk1 =50 GB
Disk2 = 100 GB
Disk3 = 256 GB
In addition, the environment includes a NAS filer. The average time to fully backup all virtual
machines on one ESX server using EMC DD Boost is three hours.
The customer is interested in implementing an EMC NetWorker solution with Data Domain as a
backup device. The backup server, storage nodes, and proxies are SAN-attached.
Refer to Scenario .
When using EMC NetWorker and DD Boost, what is the maximum number of concurrent backups
per VADP proxy server?

Scenario
A customer is looking to modernize their backup infrastructure. The current environment consists
of a single centralized data center and several remote sites. The centralized data center hosts all
core services and applications. The remote office primarily consists of sales personnel with 4000
users in North America, 500 in Europe, and 300 in Asia using file servers.
The current backup environment at the primary site uses CommVault backing up to a Fibre
Channel tape library that contains four LTO-4 tape drives. Currently they are backing up a number
of file servers as well as several databases that have average change rates of 7% daily. Remote
office backups are currently performed by having users copy files to regional file servers that are
then backed up to tape.
In the past few months, the customer has experienced problems with getting backups to finish
within their defined windows as well as issues with the tape library hardware. They now have
concerns about gaps in their backup coverage as well as the reliability of the tape media. In
addition, an internal audit shows a large amount of user-generated data is unprotected on remote
user laptops.
The customer is looking for a common platform to standardize their backups. They want a solution
which allows for a centralized infrastructure so that they do not need to rely on remote resources
to address hardware and software issues. The other goal is to move away from tape to a more
reliable disk-based solution.
Refer to Scenario .
The customer has concerns about Avamar’s ability to handle the backups of their databases.

Which recommendation should be made?

A customer has data at several remote offices that needs to be backed up over a secure WAN
connection to their data center. However, bandwidth is constrained. A major portion of their
backup data will be file system data. In addition, they have a 6 TB database in the primary data
center with a 6% change rate that needs to be backed up.

Which EMC backup solution is recommended for this customer?

A data center company is using two EMC NetWorker servers (NetWorker_A and NetWorker_B).
Each server has three storage nodes to protect 650 server applications and data.
The total amount of data being backed up is 100 TB. NetWorker_A server protects 60 TB and
NetWorker_B server protects 40 TB.
To minimize cost and simplify licensing management for NetWorker, the company decided to
switch from a traditional licensing model to a capacity licensing model.
How many licenses are needed to support the company’s requirements?

A customer currently has a multi-node EMC Avamar server with eight active storage nodes. They
are currently at 85% GSAN capacity and receiving capacity warning messages. The customer
would like to purchase four additional nodes for the system.
What is a best practice for adding capacity?

An EMC Avamar customer has added a new file system client to their moderately full Avamar
single-node server.
The single-node server is running in steady state and the initial backup is complete.
What is the estimated time to backup this file server of 3 million files each night?

A customer has an EMC Avamar server with four 3.9 TB data nodes and is backing up two large
clients in the same backup group.
The first client has:
8 GB of RAM
File system #1 with 3 million files consuming 0.75 TB of space
File system #2 with 5 million files consuming 1.00 TB of space
The second client has:

—
10 GB of RAM
1 file system containing 4 million files consuming 1.20 TB of space
How long will the steady state backup group be expected to run?

An EMC NetWorker customer uses AFTDs connected to a Data Domain CIFS share.
They want to configure clone controlled replication within NetWorker from one Data Domain to
another.
Which Data Domain license is necessary to meet the customer’s criteria?

Scenario:
The Chief Technical Officer (CTO) of a large company has directed their IT management staff to
examine corporate-wide operations and find ways to limit the cost of operations. The corporate
directives have prompted the adoption of company policies that include the use of virtualization for
all new servers and as many services as possible. The company is subject to government

regulations concerning data retention policies for confidential data. Data must be retained for
seven years.
An audit of the backup and recovery environment is performed. The exhibit shows a typical site
and how it is connected to the disaster recovery environment. Data in the primary site is
configured on VMAX storage using FAST-VP to support multiple work load types on a single
storage array.
Data is protected by SRDF/A to a remote VMAX which acts as a target for multiple sites. The
remote copy of the data is snapped and copied to tape. Retention is accomplished to
governmental standards by offsite storage of tape in a remote protected facility.
The company has indicated that it has the following requirements in any proposed architecture for
the backup and recovery environment:
Reduced power consumption
Reduced floor space consumption
Reduced storage capacity consumption
Lower WAN bandwidth utilization
Shorten RPO
Decrease RTO
Increase security
Lower total cost of ownership (TCO)

Refer to Scenario and the exhibit.

To satisfy the stated requirements, the customer wants to use a virtual appliance to limit power
and space consumption in their smaller locations. To replace the current SRDF/A replication
model, which EMC technology should be recommended?
