Perfomance between VMSnapshot and StorageSnapshot

Dear Experts, we tested this concept: https://helpcenter.veeam.com/docs/backup/vsphere/vm_processing.html?ver=95 but did not see the difference in backup speed.

Test1: We backed up a Mail Exchange server (VM) with VM snapshot:

Test2: With Storage backup

but the result was not so different

I believed Test2 should have quicker time (based on the article's suggestion)? Could you please explain and suggest? Many thanks as always!

Environment: Vsphere 6.5, Veeam B&R 9.5 update3, Win Standard 2012, MS Exchange 2016

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

So If I understand you correctly, we need to increase Veeam server's resource, such as RAM, CPUs?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Target is the bottleneck, so yes.
DP230Network AdministratorAuthor Commented:
but the target is a NAS device, not Veeam backup server?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
so target needs checking

Hi, after increased the concurrent tasks in Backup repository (NAS device) from 4 to 10, the backup speed was increased. Many thanks!
