CBT_FAILURE

Cause

• The CBT driver becomes unresponsive in case if there is any environmental problem or handle\memory leaks .
• In certain cases high levels of I/O causes snapshot quiescing to take a long time, which in turn might cause problems in releasing the bitmap file (CBT bitmap for disk) handle.

Solution

• Restart the Vembu Integration service (VIS) running on Physical Hyper-V Host and schedule the backup.
• In case of an SMB storage, restart Vembu Integration service (VIS) running on the SMB File Server Host and schedule the backup.
• Check if the Integration Service running in the SMB server and Application Server are using the same domain credentials to start the service.
• If problem still persists, CBT reset has to be done. Since this process requires more technical attention, it is recommended to contact our support team for further assistance.
