    Seems we found the problem. Seems 7.7.3 uses a version of VDDK (6.0.0) which has a bug where VixDiskLib crashes with our version of VMware.

    VDDK version 6.0.2 is where this was fixed. This code wont be implement until Netbackup 8.0

    update from Support -

    Looking at above error this is a VixDiskLib crash problem, which Vmware has identified and fixed it.
    It is a VMware issue that they recently fixed and we won't implement the VMware code until NetBackup 8.0.

    The errors we saw was the same in the below Tech doc -

Vcenter is running version 6.0.0.20100 and the ESXi hosts are running 6.0.0, 4192238
Transport type is nbd which is being used for this policy.

We have a number of VMs we backup which run fine. We have about 5 tho which keep failing with status 12.

    Hi,

    Have you confirmed that the Linux version on the VM is supported?

    See Supported VMware/Hyper-V guest operating systems in Statement of Support for NetBackup 7.x in a Virtual

    Im not sure if this version is suported. As you said this problem happens only with small number of VMs maybe this could be the problem.

      The only thing which we have changed is we upgraded from Netbackup 7.6.1.2 to 7.7.3.

      We have now worked out that the VM's which are failling have more then 1 disk. When the backup starts the backup of the 2nd disk, the job fails with status 12. We can backup the boot disk with one policy and the data disk on the a different policy which work find until we hit a client which as got 3 disks.

      Are there any timeouts for the VMware snapshots with in NBU or VMware?
