Hello, Thank you for helping with previous issue. Unfortunately we got another. We have RHV manager with several different hosts. After the backup, vm placed on RHEL shuts down. In engine.log I found moment when this happen: "VM '35183baa-1c70-4016-b7cd-528889876f19'(stor2rrd) moved from 'Up' --> 'Down'". I attached whole logs to email. It doesn't matter if it's a full or incremental, results are always the same. RHVH hosts works properly.
