Valid on Windows platforms.
Symptom:
CA ARCserve D2D full, incremental, and verify backup jobs fail. The following message appears in the CA ARCserve D2D Activity Log:
The application cannot enable changed block tracking on the virtual machine because there are snapshots on the virtual machine. To correct this problem, delete the snapshots and then resubmit the backup.
Solution:
If you disabled the Changed Block Tracking (CBT) feature and manually created a snapshot perhaps to test a condition directly from vCenter Server, the next scheduled backup job fails because the application does not recognize manually created snapshots due to a disabled Changed Block Tracking (CBT) feature. Delete the snapshot and resubmit the backup job. CA ARCserve Central Host-Based VM Backup automatically enables CBT. If you create manual snapshots with CBT enabled, backups will not fail.
Note: You can manually enable the CBT feature from the vSphere Client.
