Hello,

I have a problem with Vmware Data recovery.

When I want to backup a VM I have the error :

Failed to create snapshot for VM, error -3948 ( vcb api exception)

I'm on VMware ESXi 4.1 up 1

3 ESX on a cluster, atached to a EMC vnxe3100 eith iscsi.

Thank for your help.

Do you have the same problem with all VMs?

Version seems fine, but have you done some upgrades?

A few quick questions:

  • Are you able to create a snapshot manually?
  • What size is the VM's HDD?
  • What's the block size of the VMFS datastore?

Ok founded.

My VDR was not able to resolve my esx host !

Adding in the /etc/hosts and now works fine.

thanks
