Re: Backup fails

by nagarajan

This error will be shown when the Vembu IntegrationService installation completed partially. Follow the steps to resolve this issue,

Navigate to Program and Features in the Hyper-V host machine and uninstall the Vembu Integration Service.
Remove the Vembu Integration Service folder by navigation to C:/Program files/Vembu/Vembu Integration Service.
Remove the Vembu folder by navigating to C:/Windows/Vembu.
Delete the Host entry from the BDR backup server web console
Now add the Hyper-V host and wait till the installation completes successfully. Then configure the backup.

If this is not the case, please let us know the exact scenario to provide you the suitable solution.

Thank you. Now i get this error: CBT_FAILURE Communication could not... CBT_FAILURE Communication could not be established to the remote CBT driver [Message - START] (Refer this KB : 104012) I think i might need help to do a CBT reset. This VM that I am trying to backup was moved from another Hyper-v enviroment where it was already being backed up by Vembu. After moving it I have not been able to back it up. The new system has SMB3 as storage Please advice what to do. Regards Jacob

It seems the Vembu Integration Service is not installed on SMB server. In order to backup the VM which stores the VM data in SMB share, the Vembu agent needs to be installed in both Hyper-V host and SMB server. The reasons for this error have been explained in following KB article, https://www.vembu.com/support/knowledge-base/question/104012. You can install the Vembu agent on SMB server by adding the SMB server info on the Hyper-V backup page. https://www.vembu.com/guide/vembu-vmbackup-user-guide/getting-started.html?SetupBackupJob3.html - Nagarajan

Thanks. My SMB3 share is a Scale out file server cluster, so do i install the Agent by pointing at the cluster node SOFS or the underlying SOFS-Node1 and SOFSnode2?

Right now, we do not support scale-out SMB share. We have added this to our roadmap and started working on this feature. We haven't decided the release date yet. Meanwhile, if you would like to backup those VMs, you can use the disk image backup feature. You need to add each VM information on BDR backup server console and it will install an agent inside the VM and backup the entire VM. Refer the following user guide to know how to backup the VMs using disk image backup feature, https://www.vembu.com/guide/vembu-imagebackup-user-guide/getting-started.html .
