A customer is managing an EMC NetWorker environment with one EMC NetWorker server and one storage node that backs up approximately 70 clients. The amount of data to back up increases over a period of time that results in backups taking more than 24 hours to complete.
You use EMC Backup Advisor to analyze the current environment and find that the tape infrastructure and the network are performing fine.
What would you recommend to improve the backup performance for this environment?

A.
Add another EMC NetWorker server and balance the clients across the EMC NetWorker servers

B.
Add another storage node and balance the clients across the storage nodes

C.
Change backup schedules and spread them around to start at different times during the day

D.
Place the storage node on a 64bit server architecture
