A storage administrator is integrating Avamar deduplication backups into their existing NetWorker environment. They are required to provide a secondary copy of the backup at their disaster recovery site. How could they copy both the deduplicated backups and metadata to the disaster recovery site?
A. Replicate the deduplicated backups and clone the metadata.
B. Clone the deduplicated backups and stage the metadata.
C. Replicate the deduplicated backups and replicate the metadata.
D. Stage the deduplicated backups and clone and the metadata.
A customer has a newly installed EMC Avamar. They have the following backup clients:
-
Oracle database `Server DB1' with 1 TB of small databases, X86-64 architecture, 8 GB of RAM
-
Oracle database `Server DB2' with 1 TB of small databases, SPARC architecture, 8 GB of RAM
-
60 file servers with 10 - 100 GB of data on each, X86-64 architecture, 4 GB of RAM
The backup window is four hours and overtime is not allowed. After kicking off the initial backups, an EMC Avamar backup administrator reports that Server DB1 completed its backup. However, Server DB2 did not.
Given the information provided, what is impacting the backup time and what can be done?
A.
Server DB2 is SPARC. Hash calculations take longer than an X86; increase CPU power.
B.
File servers are taking a long time to back up, delaying the other clients. Back up Server DB2 first and then back up Server DB1 and file servers.
C.
Server DB1 is taking a long time to back up, delaying the other clients. Back up Server DB2 first, Server DB1 next, and then all file servers.
D.
Server DB2 is SPARC. Increase the amount of RAM to hold more hash cache.
A customer has a newly installed EMC Avamar Gen4S server with three 3.9 TB nodes in their headquarters data center. They are backing up two database servers with 1 TB of small databases each. The customer requires that the servers
can be restored in six hours.
The customer's database administrators need to know that they can meet their RTO. In addition, they want to know how to test the throughput rate when recovering all data and how to format the recovery command to guarantee throughput.
What is a recommendation for testing the throughput rate and recovery?
A. Using a recovery rate of 75 GB/hr/node, three nodes will meet the RTO. Use --validate for testing of recovery throughput and --allnodes for recoveries.
B. Using a recovery rate of 37.5 GB/hr/node, two nodes will meet the RTO. Use --validate for testing of recovery throughput and --allnodes for recoveries.
C. Using a recovery rate of 37.5 GB/hr/node, three nodes will meet the RTO.Use --validate and --sequencenumber for throughput testing and recovery.
D. Using a recovery rate of 75 GB/hr/node, two nodes will meet the RTO.Use --validate and --sequencenumber for throughput testing and recovery.
A client is performing a file system backup to an Avamar 7.0 server. During the hashing process, it determines that a file hash is not located in any of the cache pages loaded in RAM, but is found in the champion list. What will happen as a result of this?
A. The page associated with the champion is brought into memory.
B. The hash will be added to a page that is currently in RAM.
C. The hash will be removed from the champion list.
D. The file will undergo the sticky byte factoring process.
An EMC Avamar backup administrator wants to use their company login account for administering an Avamar server using LDAP authentication. The directory service was added successfully using Avamar Administrator. However, they still cannot successfully log into Avamar Administrator with the account.
What action is needed?
A. Associate LDAP user groups with Avamar domains
B. Add all LDAP users and passwords to the applicable Avamar domain
C. Restart the MCS process on the utility node
D. Specify the LDAP domain in the domain field of the login screen
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 deploying this configuration?
A. Replicated data will be stored in an unencrypted format on the replication target server.
B. An encryption license will be required at the replication target server.
C. Replicated data will be stored in an encrypted format on the replication target server.
D. Encryption-at-rest will negatively impact performance of the client hosts.
An EMC Avamar customer wants to use LDAP authentication for logging into Avamar Administrator. The customer has Avamar servers located in three separate data centers.
They want to restrict administration of specific backup clients to specific users.
How should this be set up?
A. Create multiple LDAP user groups and add users. For each backup client, create an LDAP map for each user group that can administer the client.
B. For each backup client, create an LDAP map for each LDAP user that can administer the client.
C. For each backup client, create Avamar users with the same names and passwords as the LDAP users who can administer the client.
D. Create Avamar domains with the same names as the LDAP domains. Move specific backup clients to each Avamar domain.
What is a characteristic of Avamar encryption?
A. All data in the client-to-server and server-to-client authentication can be encrypted.
B. All network data in both client-to-server and server-to-client authentication is always encrypted.
C. Only the authentication requests from server to client can be encrypted.
D. A private certification authority must be used to allow encryption of authentication data.
An EMC employee has been assigned to run securedelete against two clients for a total of 20 GBs on an Avamar server. During a planning discussion with the customer, they want to know what the impact on their Avamar server would be while securedelete is running.
What is the correct response to the customer?
A. GSAN will be in admin mode and no backups can be run.
B. Avamar will continue to function with a limited amount of available threads.
C. All storage nodes will operate in data=journal mode.
D. Backups and restores in progress may continue to run.
