Unknown drive type [ISO]


After applying patch 1 for you are no longer able to backup or replicate Hyper-V virtual machines, jobs fail with the  "Unknown drive type [ISO]" error. The following entries can be seen in the job log:

[timestamp] <01> Error    Failed to parse drive xmlnode. Xml: [<drive0><pathname type="string">C:\Users\administrator\Downloads\name.ISO</pathname><type type="string">ISO</type></drive0>]   at Veeam.Backup.Common.CExceptionUtil.RegenTraceExc(Exception originalExc, String formatString, Object[] args)
[timestamp] <01> Error       at Veeam.Backup.Core.CHvVmConfigFile.ParseDrive(XmlNode node)
[timestamp] <01> Error       at Veeam.Backup.Core.CHvVmConfigFile.ParseController(XmlNode node, Int32 controllerNum)
[timestamp] <01> Error    Unknown drive type [ISO]   at Veeam.Backup.Core.CHVVMCfgDrive.ConvertStringToType(String typeStr) 


XML files of the backed up virtual machines are not parsable, when Hyper-V host with non-English locale is used. 


The issue will be fixed in version 6.5, as a workaround change the locale settings of the operating system to English
