I was recently looking at an issue where a number of virtual machine backups were failing with the following error message:
internal error occurred during execution, please contact Quest support if the error persists. Error Message: 2712 - can't create the directory cifs:<username>@<ip address of repository>/<repository path>
On investigation, I found the following knowledge base article which discussed modifying the ‘CifsTimeout’ value in the ‘C:\Program Files (x86)\Quest Software\vRanger\Service\Vizioncore.vRanger.Service.exe.config’ file (https://support.quest.com/SolutionDetail.aspx?id=SOL99156).
Following the recommended change being applied and a restart of the ‘vRanger Service’ this backup job failed with the above symptom on the next run.
Further investigation, highlighted an issue with the transport selection and the version of the virtual appliance being used. In order to resolve this issue I have provided implemented a workaround to modify the transport selection to be on the vRanger machine rather than the virtual appliance.
The current version of vRanger being used is 5.5.0.25454 and the virtual appliance is 1.7.0, this appears to be resolved in versions above 1.8.0 in the virtual appliance, so the next plan is to upgrade the current version of vRanger and deploy upgraded virtual appliances and then to revert the transport selection to virtual appliance.
