Backup Recovery Solutions Expert Exam for Technology Architects v6.0

If multiple backup streams are written to a backup device at the same time, which feature is being used?

An EMC Avamar customer regularly backs up their SharePoint distributed farm. They noticed that with the backup taken today, Avamar has listed the backup under a different farm name.
What is a possible cause?

An EMC customer is currently using NetWorker, Data Domain configured as an NDMP tape server, and VNX. The Data Domain and the VNX both have supported HBAs. The customer configured the NDMP backup in NetWorker and has noticed that the data is not traversing over the HBA cards. Rather, the data is being set over the LAN.
Why is the backup data being backed up over the LAN directly to the Data Domain system?

An EMC NetWorker customer is backing up several different applications to Data Domain devices in their production data center. They want to replicate their daily sensitive database backups to another Data Domain system located in their disaster recovery data center.
Both data centers are linked with only a 10 Mb link.
Based on EMC best practice, which type of replication should be used?

You have been assigned to resolve a customer's EMC VNX file-level backup design issue.
They are using EMC NetWorker with Data Domain as a LAN backup device. The IT infrastructure consists of LAN and SAN components.
Which solution provides the least amount of traffic over the production LAN and SAN?

An existing EMC NetWorker customer has already integrated an EMC Avamar server with
NetWorker. They have tried to backup their clients to the deduplication node. However, a message occurs stating that the backup session is waiting for a writable volume.
What is the possible cause for this message?

A customer has a large ESX environment managed by one vCenter server. They want a backup solution using EMC NetWorker and Data Domain devices. They want to perform
SAN-based backups using physical NetWorker proxy hosts. In addition, they want to run
150 virtual machine backups at the same time.
When creating a backup design for this environment, what is a vCenter consideration?

A customer had configured their EMC NetWorker environment to use Data Domain Boost,
CIFS, and NFS protocols to back up their local environment. After analyzing the performance of each protocol, the decision was made to only use the DD Boost protocol.
The customer reconfigured the NetWorker clients to backup to the already configured Data
Domain devices and disabled CIFS and NFS on the Data Domain. After scheduled backups were performed, all backups started to fail.
What must be done to perform a successful backup?

A customer has an EMC VNX series NAS with a total of 20 TB of user data. The customer wants to use EMC NetWorker to backup the VNX to a Data Domain VTL. The VTL is configured with four tape drives that are zoned to the backup server.
What is the minimum number of pools required to have a successful NDMP backup?

An EMC NetWorker customer has asked you to deploy a Microsoft Exchange 2010 backup solution using NMM. They have two Microsoft Exchange 2010 servers in a Database
Availability group (exch2010a and exch2010b). The client resource for 'exch2010a' is shown in the exhibit.

An EMC NetWorker customer has an 8 TB Oracle database. They want to know the most efficient way to backup with NetWorker to Data Domain deduplication.
When integrating NetWorker with Data Domain, what is an Oracle best practice?

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 willhave 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.
Which additional piece of information must be specified on the command line when using nsrdasv to manually perform backups of the Domino instances?

Refer to Scenario 1.
The customer has decided to implement DAOS on both Domino instances. What is a requirement to ensure consistent recoverability of all data?

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 needs to protect a number of new file system clients. How can this be accomplished?
