We're battling an issue with a virtual SQL server and vCenter sync'd snapshots from our storage array. We're not having snapshot failures, but the snap is causing just a bit of disruption so that some of our apps are timing out with VSS snap creation. We don't have the problem when using Veeam's application consistent snaps so I think there must be something else wrong on my guest OS. I know I can disable unnecessary VSS writers, but I'm a bit unsure which ones it would be safe to disable and still get the consistent snaps in Nimble.
Here is what we have on our list of enabled VSS writers. There is a way to disable them using this article: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1031200
