What is a main advantage of using DD Boost instead of CIFS or NFS for a backup?
Answer(s): D
Dell EMC Data Domain Boost software distributes parts of the deduplication process to the backup server(s) or application client(s), leaving the Data Domain system, powered by Intel® Xeon® processors, to focus its energy on determining what is unique and writing the new data to disk. With DD Boost, only the unique data has to travel from the backup server or client to the Data Domain system. DD Boost also gives the backup application control over replication

What happens to the data when it is moved from the active tier to cloud tier?
Answer(s): A
Every file has a meta-data. Meta-data of the files which is getting moved is stored on active tier and data and metadata is moved into the cloud. There is no multiple data-movement policy set on single mtree. Data moved to particular cloud unit depends on datamovement policy. And only the unique data is sent to the cloud. This is done using the deduplication.

A backup administrator is tasked with monitoring PowerProtect DD capacity metrics. The administrator is backing up 2 of data daily with a reduction rate at 5x. After data reduction, subsequent full backups compress down to 100 GB.The initial backup requires 400 GB with a 10 percent increase in the data each day. Each incremental backup is 200 GB. After data reduction, each incremental backup is 20 GB. What is the weekly burn rate (GB) after six daily incremental backups and one weekly backup?

What is the preferred method to ensure backups are protected against deletion or corruption?
In order to keep data protection tools from getting overwhelmed by the enormous capacity requirements generated in today's data centers, technologies which enable data to be tiered from primary backup to secondary long term retention/archive are becoming more attractive. Dell EMC Cloud Tier technology integrates with an Dell EMC ECS Object Storage system (on premises or hosted private cloud) to provide a massively scalable architecture. By leveraging the capabilities of both ofthese platforms, IT administrators and architects can continue the path of consolidating critical backup processes, protecting complex environments mixed with unstructured data, database engines, virtual environments, while at the same time providing the ability to meet long term.
