Question 2

Which functionality is recommended by Dell EMC to be disabled on backup software when configuring Dell EMC Data Domain VTL?

AMultiplexing

BMultithreading

CParallelism

DTarget Session

Answer : A

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.
