A customer wants an EMC Avamar solution that provides 8 TB of deduplicated data protection. In
addition, they need to protect a VNX system and export data to tape. They anticipate data growth
of another 6 TB in the next year.
Which Avamar components should be used to architect the solution, in as few nodes as possible,
while meeting sizing best practices?

While designing an EMC Data Domain solution for a customer, you want to determine the amount
of storage capacity needed. You have discovered the following information:
2 TB full backup @ 5x compression
10% daily data change rate
4 incremental/week @ 10x compression
1x full per week @ 25x compression
Retention period = 4 weeks with no data growth

—
What is the burn rate (in GB)?

A customer has an environment that consists of 50 clients, EMC NetWorker, and a Data Domain
system. The customer wants the ability to obtain individual client deduplication ratios.
What must be done to ensure there is no performance loss on the Data Domain system?

An existing EMC NetWorker customer is planning to integrate EMC Data Domain systems into
their backup infrastructure. They would like to:
Backup their Microsoft Windows client data using CIFS to a Data Domain system
Takeweekly Data Domain system snapshots of Windows client backup data
Backup their Linux client data using NFS to a Data Domain system

– —–
Take daily Data Domain system snapshots of Linux client backup data
Based on EMC best practice, what should be considered when designing the Data Domain file
system layout?

A customer would like assistance with the design of an EMC Data Domain environment. Based on
best practices, what should the customer know about Data Domain MTrees?

A customer has two data centers and each data center has an identical EMC Data Domain
system. The customer needs a replication strategy that meets the following objectives:
User name and passwords are unique
/data/col1/backup are identical
Data Domain destination directory is read only

– —
Ownership and permissions remain identical
Which type of Data Domain replication should be configured?

You are sizing an EMC Data Domain system for a new customer. The customer has provided their
capacity and performance requirements for the system.
When selecting a Data Domain model to meet their requirements, according to best practices,
which buffer size should be used?

While designing an EMC Data Domain solution, you need to determine the required amount of
storage capacity. The following information was gathered from the customer:

—– —
2 TB full backup @ 5x compression
10% daily data change rate
4 incremental/week @ 10x compression
1x full per week @ 25x compression
Retention period = 4 weeks with no data growth
What is the minimum amount of storage needed to support this solution?

In an EMC Data Domain environment, what is a supported Extended Retention replication
configuration?

A new EMC Data Domain customer has a requirement to store the maximum amount of backup
data on their Data Domain system. They are deciding on the type of local compression to use for
their backups.
When planning the Data Domain design, what should the customer know about the compression
types?
