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 Net Worker. 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 investigations, you notice that the backup job quiesces the file system. This is creating lock contention issues on open files and not allowing users full access to data when the backup job runs.

What advice should be provided to the team to eliminate lock contention and allow full access to users?
A . Create a cron job to remove all locks before each backup.
B . Add A100 Backup Accelerators and configure for three-way NDMP
C . Stop using an NDMP-based backup strategy.
D . Enhance the backup strategy using snapshots for backups.
