I am running Acronis Backup Advanced (Version 11.5 Update 6). Acronis Backup Management Server (build 11.5.43994) on a Windows 2008 R2 Server that is a standalone server.  It's purpose is to backup 3 virtual servers running on a VMWare ESXi 5.5.0 host.

After running the backup it I receive an error log on one of the three virtual servers that says:

Command 'Backing up' has failed.

I do not have any plug-ins installed on the VMWare Vsphere client.

I have rebooted the VMWare host concurrently with the Acronis Backup management server.  This did not fix the problem.  I have deleted the Managed Vault and the Backup plan and then re-created a new Vault and backup plan.  This did not help.  I made sure that all of the Acronis services are running on the Acronis Backup management server.

 

Please help.

Hi,

The error is thrown by VMware when a snapshot of the backed up VM is created: "Change tracking target file already exists." . The problem is related to enabling VMware Change Block Tracking on the protected VM which likely has some orphaned .ctk entries. Please check the solution suggested in the following thread and see if it helps:

P.S. alternatively you can reset CBT on the problematic VM (trask.hallco.local) as described in https://kb.acronis.com/content/45682

Thank you.
