"Cannot create temporary redo log directory" when running a file based VCB backup


When' creating a file based VM backup using VCB the "Cannot create temporary redo log directory" error is seen. This occurs with either vcbMounter or the generic/pre-command.wsf scripts. FullVM backups work without issue.

A details log follows:
