What is a best practice recommendation for Veritas NetBackup servers configured for VTL backups to Dell EMC Data Domain systems?

D . Disable fragment size

Answer: B

Explanation:

Multiplexing, compression, and encryption of backup data were introduced to provide read parallelism as well as enhanced security and performance during backups. Backing up to a Data Domain system is inherently more secure than tape, and does not suffer performance degradation due to slow backup streams. Thus the recommendation is to disable any of these features when using a Data Domain system as the target for RMAN.
