Backup Recovery - Avamar Expert Exam for Implementation Engineers: E20-895

A company's backup environment consists of both file system and database clients. An integrated Data Domain system was added to their existing EMC Avamar single-node Gen4S server to add backup capacity. Backups of several large Exchange and Oracle database clients were then reconfigured to back up to Data Domain storage. After several months, the backup administrator notices that the metadata utilization graph appears in red.

What is a possible cause?

A. Avamar cannot convert unused data stripes to metadata stripes.

B. Data Domain is unable to clean enough metadata containers to hold the backup data.

C. The Avamar server has exceeded 65% of GSAN utilization and backups have stopped running.

D. Avamar garbage collection has failed to free up the necessary empty stripes.

An EMC customer is looking for options to back up their smaller remote sites with easy remote management, so they want to use Avamar Virtual Edition (AVE).

Before installing ESX hardware at the remote sites they want to do a proof of concept using the existing ESX 4.1 server that they have at the data center. They have provisioned 2 TB of virtual disks using VMAX thin provisioning with RAID 1

data devices. They have tested the backup of three servers and do not see an improvement.

According to best practices, what should the customer have done to avoid performance issues?

A. Use thick devices for the virtual devices.

B. Use ESX 5.0i to host the AVE server.

C. Use RAID 10 for the virtual devices.

D. Use lazy zeroing to zero out all blocks.

An Oracle client is performing backups to a Dell EMC Data Domain through Dell EMC Avamar. It performs full backups once a week and incrementals on all other days. An administrator adds a second Data Domain to the Avamar and directs the Oracle backups to it.

What must be done for backups to run as expected?

A. First backup to the new Data Domain must be a full

B. Client must be re-registered to the new Data Domain

C. Full backups must be migrated to the new Data Domain

D. Old Data Domain must be retired
