snapshot removal task failed to start

I have a few image level backups that appear to fail in the activity log because of the snapshot removal process. For some reason, these VMs take about 30 seconds before the snapshot removal starts. Avamar sees this as the task failing. The backup is actually stored in Avamar, and the removal task does eventually begin and complete.

To accommodate this lag, is there a timeout or wait flag that can be added to the dataset so that Avamar sees the task start?

    Please provide info about your environment, i.e. VMware/HyperV, Avamar Ver. etc. for better understanding.

    The exact error is...

    2016-04-19 23:26:49 avvcbimage Error <17773>: Snapshot (snapshot-43795) removal for VM '[FBPNutanixCluster01-NFS-Container] HOPDC05/HOPDC05.vmx' task failed to start

    The solution in my case seems to be to force the transport method.

    [avvcbimage]transport=nbd:nbdssl

    I am getting the exact same error.  Where exactly did you enter these settings?

    I am using Avamar to make an image backup of vcenter 6 appliance, but it keeps failing.

    1. Edit Dataset

    2. options tab

    3. Select plugin

    4. Click more

    5. Enter the attribute ([avvcbimage]transport) and the value (nbd:nbdssl)

    I think this resolved my issue.

    The VCSA backup ran last night with no issues.

    For the plugin I chose "Linux VMware Image" since this is the VMware Appliance that I am backing up.

    I'm backing up the VCSA appliance 6.1 with Avamar 7.2.
