RAID, RAIN, and checkpoints
A customer requires the ability to recover data while backups are being written to the same media. Which EMC NetWorker device type supports this operation?
A customer has an existing environment where a tape library is the target for backups. The tapes are then shipped offsite where they are stored and can be used for disaster recovery. The customer wants to eliminate the tape library and any truck delivery but still have copies sent offsite. They want to keep their backup process in place. What is the most efficient type of Data Domain replication that meets this requirement?
A customer plans to deploy deduplication in an EMC NetWorker environment. For data backed up to the deduplication node, where is the metadata in the form of hashids sent?
How is the communication between a Data Protection Advisor Collector and the Server performed?
Encrypted XML over TCP ports
You are backing up two different NAS servers, each with direct-attached tape drives. Backup Client X has 10 files of 100 MB each. Backup Client Y has 1,000 files of 1 MB each. What will happen under identical backup infrastructures?
Client Y will generate more backup catalog entries
Which EMC NetWorker policy is configured to define the length of time that records are retained in the Client File Index?
An EMC Disk Library customer is considering using Remote Copy between two engines. A policy will be configured to copy data when 50 MB of data is sent to the virtual tape. How does the data transfer occur?
Incremental data is sent to the target engine when the virtual tape is unmounted and 50 MB of new data has been written
An Avamar administrator wants to run multiple backups from their Celerra through their single NDMP accelerator node. Based on EMC best practices, what is the recommended maximum number of backup jobs that the administrator can run at once, assuming there is enough RAM?
Due to a bottleneck on the LAN, a potential EMC customer is unable to meet their current SLA on backups. Which Avamar characteristic addresses the customer's issue?
Transferring only unique, sub-file data
A customer is using the NetWorker Module for Microsoft Applications (NMM) to protect the following environment: * Microsoft Exchange Server 2007 using Cluster Continuous Replication (CCR) that resides on an EMC CLARiiON disk array. * A Microsoft Volume Shadow Copy Service hardware provider is used to create point-in-time copies of production data. What is a characteristic of an NMM backup operation?
NMM automatically recognizes the passive node after an Exchange CCR role change
An EMC customer is implementing an EMC Disk Library (EDL) as the primary target for backups using NetBackup. After a predefined period of time, data needs to be moved from the EDL to physical tape. Data movement to physical tape and recovery from physical tape should occur without manual intervention. Which feature satisfies these requirements?
An EMC Avamar customer is expanding their backup environment to include their many virtual machines in addition to their physical file servers. Which Avamar deployment provides the least amount of change to their existing backup procedures?
