Troubleshooting CBT_FAILURE in BDRSuite
KB ID: 104012
Cause:
The CBT (Changed Block Tracking) driver in BDRSuite may become unresponsive due to environmental problems or handle/memory leaks. Additionally, high levels of I/O can lead to extended snapshot quiescing, potentially causing issues in releasing the CBT bitmap file handle.
Solution:
To resolve the CBT_FAILURE issue in BDRSuite, follow these steps:
1. Restart the BDRSuite Integration service (BIS) running on the Physical Hyper-V Host and reschedule the backup.
2. If using SMB storage, restart the BDRSuite Integration service (BIS) on the SMB File Server Host and reschedule the backup.
3. Verify that the BDRSuite Integration Service running on both the SMB server and Application Server are using the same domain credentials to start the service.
4. If the problem persists, a CBT reset may be required. This process requires technical expertise, so it is advisable to contact our support team for further assistance.
By following these steps, you can effectively address the CBT_FAILURE issue and ensure smooth backup operations with BDRSuite.
