An EMC Avamar customer is in the testing phase of their new solution. They have backed up
several clients and are now doing some restore tests. They have found that the restore time is not
consistent. The restore time decreases if more than one attempt at the same restore is performed.
Why is the customer seeing these results?
A.
Backup jobs are running
B.
Restore data is in memory
C.
Garbage collection is running
D.
Restore data is on faster disks
Correct ans is B:Restore data is in memory
Exp:- The 2nd restore in a row of same data will be faster as the data is restored from memory.

Correct – In a restore, data is retrieved from the Avamar server, sent to the client, collected in client memory, ordered, uncompressed and written to disk on the client.
If they had not mentioned that 2nd restores were taking less time, then you could consider maintenance jobs running concurrently with restores will impact performance by 70% or more, best to run restores outside of the server maintenance window.
