When we try to run a differential backup using the vmware option, it always results in the problem that nothings will be backuped in differential mode. And the following error is listed for every vm "e00095b4 - incremental\\differential backup methods are not supported for this vm. the backup job failed, since the option 'to fall back to a full backup' was not selected". All vm's are converted to hardware version 7 and remote agent is installed on every vm
