Since I have upgraded to Veeam 8 Patch 1, I have some problems on 1 VM (SRVAD). My configuration is quite simple, 2 ESX + 1 SAN and 8 VM.
The backup of the différents VM is OK, but after processing the SRVAD, the 2 VMDK are removed from the VM.

I just opened a case with the support team of Veeam: Case 00717834
Just removed the Patch 1 and everything looks good again.
Never had any problems when upgrading Veeam B&R, seems to be an isolated problem ?!?
But I want to be sure, because I have a lot of other clients to upgrade in the next days.
Please keep me inform.
Thanks!
