A customer wants to know why their backup performance to the Avamar multinode f\grid has
decreased. Initially they were seeing an ingestion rate of around 5 to 7 GB/hr/node. Recently they

estimated that it has slowed to around 3 to 5 GB/hr/node.
What is a probable cause for the decrease in the average ingestion rate?

A.
HFS check has not been completing successfully

B.
A large number of backups have been expired, causing new stripes to be created

C.
New stripes are no longer being created and steady-state has been achieved

D.
Garbage collection is not running, causing stripes to fill and new stripes to be created
