Title: Backup Success with CBT Failure: Handling Full Resend of VM Data in BDRSuite
This knowledge base article addresses the scenario where a backup operation is reported as completed successfully, but Change Block Tracking (CBT) fails for a specific VM in BDRSuite. This situation arises due to multiple configurations of the same source VM for backup or replication jobs, leading to CBT tracking failure.
The mentioned remarks, "Backup Completed Successfully but CBT failed for this VM," occur when a VMWare backup or replication job finishes with this outcome. This arises from configuring the same source VM multiple times for backup or replication tasks, resulting in CBT tracking failure.
To address this issue, follow these steps:
1. Handling CBT Failure:
- When a VM encounters CBT failure, the subsequent incremental backup or replication will automatically be treated as a full backup/replication for that specific VM.
- The CBT Driver will initiate tracking changes from a particular timestamp, ensuring accurate synchronization.
Note: This solution is provided to address the situation where backup operations show success but encounter CBT failure for a specific VM in BDRSuite. By allowing subsequent incremental as full backups and resetting CBT tracking, the issue can be resolved to ensure proper data synchronization.
