Hello there.
About four months ago my Windows Server 2012R2 started to get an error "Windows Backup Failed to Get an Exclusive Lock on ESP"
Here is log: "The backup operation started at '2020 - 04 - 20T11: 06: 04.405816800Z' failed with the following error code '0x8078011E' (Windows Backup failed to obtain an exclusive lock on the EFI system partition ( This may occur if another application is using files in ESP. Try the operation again.) Check the event details for a solution and run the backup again after solving the problem."
First off I google it and found something about Kaspersky blocking EFI partition. I uninstalled it, but problem remains the same.
Someone could enlight me?
