Yesterday I have updated our B&R server to Update 3. Today in some jobs VM backup fails. This is the error message from the log which is sent by email
Processing Webserver Error: File does not exist or locked. VMFS path: [[DatastoreBlade1] Webserver/Webserver.vmx]. Please, try to download specified file using connection to the ESX server where the VM registered. Failed to create NFC download stream.
For those VM the backup fails even the step "getting file info from Vsphere" fails.
I have a job which backups 13 VMs. 5 have the error and 8 are okay.
I guess, it must have something to do with yesterday upgrade to Update 3. Before the update the backups ran fine for months.
