We are currently using B&R 9.5 Beta on a test system. Build number: 220.127.116.114.RC1
Just stumbled over a bug that has been in the software before: veeam-backup-replication-f2/error-an-error-occurred-while-parsing-entityname-line-1-t16761.html
Issue: When trying to backup a VM that has a folder including an ampersand "&" in its configuration (eg. because an ISO image has been mounted as a CD drive), the backup job will stop with the error "An error occurred while parsing EntityName. Line 1..." In our case it was the following folder which was mounted as a cd drive to install Veeam B&R: D:\temp\Beta\VeeamBackup&Replication_18.104.22.1684.RC1.iso
Hyper-V host Windows Server 2016
VM to backup also Windows Server 2016
Seems to be an issue with the XML-processing library in use...
Hope this is not a duplicate to a previous message but as Veeam support didn't know of this issue until last week, I guess it's new.
