Hello there, I have a Windows Server 2012 R2 Standard with Hyper-V and Kaspersky Endpoint Security 11.1.2.63 installed. A week or more ago Windows Server Backup started to fail, it says “Windows Backup Failed to Get an Exclusive Lock on the EFI System Partition”. After I restart the server Windows Server Backup finish correctly. I guess it have something with Kaspersky. Someone could help?
