This knowledge base article addresses the "VM Not Found" error encountered while attempting to execute an incremental backup job within the BDRShield application. The error arises due to the unavailability or corruption of the virtual machine's configuration files.

The "VM Not Found" error occurs when the required configuration files of the virtual machine are either not accessible or have become corrupted, preventing the successful execution of the incremental backup job.

To address this issue, follow these steps:

1. Verify Configuration Files:

1. Check for the presence and integrity of the VMware configuration files, specifically the *.vmx and *.vmdk files.
2. These files should be available within the OS VMFS file system.
   

2. Use vSphere Client Console:

1. Power on the guest operating system associated with the affected virtual machine through the vSphere Client console.
   
2. This action will provide precise error details related to the issue.
   

By carefully inspecting the availability and integrity of the configuration files and utilizing the vSphere Client console, you can identify the root cause of the "VM Not Found" error during incremental backup jobs in BDRShield and proceed with the necessary corrective actions.

Note: This solution offers guidance for resolving the "VM Not Found" error, ensuring the seamless execution of incremental backup jobs in BDRShield.
