Exam E20-891: Backup Recovery Solutions Expert Exam for Technology Architects (update February 18th, 2017)

What is a requirement to satisfy these requests?

Scenario 6 A customer recently implemented an EMC Avamar solution in their primary data
center. The environment consists of several Microsoft applications, including Microsoft
SharePoint, Exchange, and SQL. An EMC Data Domain system was also deployed behind
Avamar as the backup destination for these applications. There are also several file system
clients that have been configured to back up directly to the Avamar server. One Avamar
server and two Data Domain systems have been deployed to support this configuration. The
Avamar server is operating close to full capacity and there is no room for expansion since it
is already fully provisioned with the maximum number of nodes. The Data Domain systems
have plenty of capacity left; each system is currently at 35% of utilization. Refer to Scenario
6. The customer wants to replicate the Exchange backup data to one Data Domain system
and SQL backup data to a different Data Domain system. What is a requirement to satisfy
these requests?

How can the customer’s needs be achieved?

EMC NetWorker is being proposed to a customer as a backup and recovery solution for a
Microsoft SQL server. One of the customer’s concerns is the ability to support database
recovery at any requested time. Microsoft SQL Server Management Studio is used to
display the properties of the user databases, as shown in the exhibit. How can the
customer’s needs be achieved?

Scenario 1 You have a customer with a large IBM Lotus Domino environment. The
customer is in the process of migrating from a UNIX to a Microsoft Windows infrastructure.
As part of this process, they are going to perform a refresh of the hardware and software
that Domino is running on. In addition, they will migrate all client backups to a new EMC
NetWorker environment. The new backup environment consists of a NetWorker server and
two storage nodes running on Windows 2008. The Domino environment consists of a single
server running two instances of Domino. The total amount of data that needs to be backed
up is approximately 900 GB. The Domino server will have connections to both the SAN and
the LAN. They would like to perform hot backups of the databases using the NMDA but are
leaving specific design decisions to you. Additionally, the customer would like to send all
data to disk for onsite backups and clone the first full backup of the year to tape for
long-term offsite retention. The backup target infrastructure consists of a single Quantum
i2000 tape library with six LTO-4 tape drives in addition to two EMC Data Domain 890s.
One Data Domain will be located at their primary site. The second Data Domain is at the
disaster recovery (DR) site as a replication target for the first. One of the customer’s major
concerns is the backup speed of the Domino environment. They are interested in any best
practices they can implement to improve backup performance at the Domino level.
Furthermore, they are looking for guidance in using NMDA to backup the data and leverage
their backup infrastructure in the most efficient way. Refer to Scenario 1. What must be
done to ensure the transaction logs and any changed database files are backed up during
an incremental backup of each database instance on the server?

Refer to the Exhibit. A customer has asked you to deploy a Microsoft Exchange backup
solution. The customer’s environment consists of the following: • Microsoft Exchange Server
2010 • EMC NetWorker Module for Microsoft Applications • EMC NetWorker server software
• EMC Data Domain Which Application Information attributes need to be set for a successful
Data Domain Boost backup?

6. The customer noticed that while backing up the Microsoft Exchange clients, a significant
amount of data is being stored on the Avamar server. The Exchange clients are configured
to send their data to the Data Domain system. What is an explanation for this behavior?

Which configuration setting must be added and/or changed?

Refer to the Exhibit. A customer has asked you to deploy a Microsoft Exchange backup
solution. The customer’s environment consists of the following: • Microsoft Exchange Server
2010 • EMC NetWorker Module for Microsoft Applications • EMC NetWorker server software
• EMC Data Domain The customer wants to keep the point-in-time copy on disk and store
another backup on the Data Domain device. Which configuration setting must be added
and/or changed?
