Case Study 5 – Refer to the Exhibit.

Backing up data from a Dell EMC Isilon cluster exceeds the company’s backup window. Because the company has a large amount of data with a continuous high growth rate, they want to change their backup strategy. The Gen 6 Isilon cluster consists of 24 nodes.

Their current backup strategy is an NDMP three-way backup performing weekly full backups to tape and incremental backups each night. The strategy uses Dell EMC NetWorker. The DMA uses Include paths to specify what data to backup. All data on the cluster must remain accessible.

The company’s IT team is now looking for a method to increase the performance of their backups. After some investigation, you notice that the backup job targets two paths. This could be the cause of the lengthy backup times.

What advice should be provided to the team?

Options:

A.

Exclude the largest datasets from the backup job

B.

Add A100 Backup Accelerators and configure for two-way NDMP

C.

Create more parallel streams to utilize multi-stream NDMP backups.

D.

Change the backup strategy to token-based backups.

-005 ms average jitter

Netstat on the local network shows:

-05% average re-transmission rate

Hostcache list:

-20 ms average roundtrip time across all clients

The administrator shows you the following iperf output:

-890 Mb/s average bandwidth

-98.8 ms average jitter

B.

Numbers remain within the recommended range

C.
