An EMC Avamar customer is currently using a 2 TB Avamar Virtual Edition (AVE) for their backup environment. They want to begin backing up several Oracle databases and file servers running on a new ESX server. It is determined that a separate AVE should be added to the backup environment for these new backups.
What should be done when implementing the new configuration?

A customer has an EMC Avamar integrated with a Data Domain system as a backup solution. They would like to use encryption for the backups that are directed to the Data Domain system.
Which method(s) of encryption can be used in this environment?

An EMC Avamar customer has a Celerra running DART 6.0 with 20 TB of data. There are approximately 10 million files distributed across two Data Movers. They would like to backup the NAS in approximately five hours. What is the maximum number of streams that can be configured?

An EMC customer has a three-node cluster with the Avamar Windows client installed. Each node has the Avamar Exchange 2007 plug-in installed. What should be done to avoid backing up the same data multiple times within a backup window?

An EMC Avamar backup administrator wants to use their company login account for administering an Avamar server. The procedures were followed successfully to update the configuration for external LDAP authentication. However, they still cannot successfully log into Avamar Administrator with the account. Which action is needed?

An EMC Avamar customer is running a backup that is being written to a Data Domain system. The Data Domain cleaning schedule runs at 8 A.M. on Tuesday mornings. Avamar maintenance runs daily at 6 A.M. A backup has completed successfully; however, it is no longer needed. The customer manually deletes the backup on Wednesday afternoon using the Avamar Administrator.
When is the space reclaimed on the Data Domain system?

A customer has been performing full backups of their SharePoint farm to an Avamar server. They have installed the Avamar SharePoint backup client without the
GLR feature. They want to perform a restore of only one web application, but do not want to take any of the SharePoint farm servers offline. What should be done?

A customer is successfully backing up 50 virtual machines (VMs) hosted on two ESX hosts. There are two datastores and two proxy servers used for VADP-based backups. They deploy another proxy server to backup 10 new VMs residing on a new datastore. The backups for the new VMs failed with the following error:
Event Code: 30931 - Failed to initiate a backup or restore of a virtual machine because no proxy was found to service the virtual machine. What caused this error?

A customer has setup their EMC Celerra to backup through an Avamar NDMP Accelerator Node. They are not seeing any increased performance since the initial backup. They have investigated the Celerra and there are no outstanding issues.
What is a potential reason for the poor backup performance?

An EMC customer is using NetWorker with integrated Avamar deduplication nodes. They have expired a large amount of data on the NetWorker server. After several hours, they notice that the index entries have been deleted from NetWorker. However, data has not been removed from the deduplication node. What is a potential reason?

An existing EMC Avamar customer has noticed that garbage collection is not running properly on a daily basis. The garbage collection logs show the process failing with the MSG_ERR_FULL error each time it attempts to run. The Avamar Administrator reports the server capacity as 96%.What could be causing garbage collection to fail?

An EMC customer has received a warning indicating that their Avamar server has crossed the 80% capacity threshold. Backups are completing within the backup window and there have been no recent increases in the client change rates. Maintenance processes are running successfully and garbage collection is freeing up space at its expected rate.
What is the best course of action to take at this time?

An EMC Avamar customer has a large virtual machine (VM) with a small backup window available. On the weekends, there is a larger backup window available.
Most of the files on the VM do not change daily but the few that do change are critical.
How can the customer protect the critical files every day without exceeding the daily backup window while still meeting their SLAs to protect the entire VM image?

When using an EMC Avamar to backup an Oracle database, an error similar to the following is received:

What is the likely cause for these errors?

Click on the calculator icon in the upper left corner.
A current EMC Avamar customer is having trouble completing replication on a nightly basis. The customers networking team sees that Avamar is only utilizing about 40% of the available bandwidth on their 45 Mb WAN link. The latency or round trip time on the WAN link is 78 ms. The customer would like to tune Avamar replication to use more of the available bandwidth
What is the Bandwidth Delay Product for this link?

An EMC Avamar customer has a two-node Microsoft Exchange 2003 cluster with one instance of Microsoft Exchange. They are backing up the storage groups only. To ensure successful backups of the Exchange data, what is the order for installation?

You are adding a deduplication node to a customer's EMC NetWorker environment. The NetWorker clients currently back up to tape and perform full backups on
Sunday and incremental backups on the other days of the week. In the new solution, all clients will back up to the deduplication node. The speed of recovery and higher deduplication rates are important to the customer. Which NetWorker schedule is recommended?

An EMC Avamar customer has a backup that is running longer than expected. EMC Support is asking for more logging information from the client. What is the recommended method for providing this information?

A customer has a client server backing up to an EMC Avamar system and backups are running longer than expected. The client server has 1 GB of RAM and is backing up 5 million files. The Avamar backup dataset has been created with default option settings.
The customer is looking for a way to make this backup run faster. However, they cannot currently implement any changes that would require downtime on the client.
Which action should the customer take to improve backup performance?

A customer has purchased a backup solution consisting of an EMC Avamar server with Data Domain integration to support Microsoft Exchange VSS backups.
Test databases were created for the purposes of confirming end-to-end functionality. The test database backups, using the Exchange VSS plug-in, complete successfully but they are being stored on the Avamar server instead of being sent directly to the Data Domain system.
What is the most probable cause of this behavior?

A customer wants to protect their DB2 databases with EMC Avamar. You have configured some test databases and have performed several successful backups of various types. They would now like to restore the databases to complete their testing.
In order to restore from an online backup with archive logs, which prefix should they look for when choosing a backup file?

An EMC customer wants to implement a backup solution for their virtual machines. They are interested in Avamar deduplication features. In addition, they want to minimize the backup capacity required. Their ESX environment is running optimally with sufficient resources.
Which VMware backup method will provide the most optimized capacity?

A customer wants to protect their DB2 databases with EMC Avamar. You have configured and validated successful completion of both hot and cold database backups. You now need to validate that you can restore from the cold database backups. To recover after shutting down the database, which prefix should the backup file contain?

An EMC Avamar customer has a requirement to backup SQL databases with multiple filegroups. As a test of data recovery procedures, the backups need to be restored to a different server.
Which restore method should be used?

A new EMC Avamar customer is planning to have a multi-node Avamar server replicate to an offsite multi-node Avamar server. Because their data is extremely sensitive, they are concerned about the security of the backup environment.
The customer is planning to encrypt all network transmissions. They also want to use encryption-at-rest on the primary Avamar backup server to provide an additional level of data security for their stored backup data. What is an expected outcome of this configuration?
