So came across this problem after upgrading to 9.5 and my colleague upgrading our vshpere environment to 6.5. Instantly I figured it was his fault but before outing him publicly I thought id google. Found this topic and I like others can concur that before 9.5 all was working.
Id tried everything and then found JasonRoss' fix and yep its worked. I think hes spot on with regards to it being a design flaw from veeam.
Anyways if you are experiencing this issue then follow what Jason has said and it will resolve
