Backing up a cloned virtual machine that has the same UUID

When a virtual machine is cloned outside the vCenter Server, it may have the same UUID as the original virtual machine. If this cloned virtual machine is selected for a backup, the plug-in may back up the original virtual machine instead of the clone.

To correct this issue, you must change the UUID of the cloned virtual machine. For more information about changing the UUID of a virtual machine, see

Backing up virtual machines that are protected by vSphere FT

VMware vSphere Fault Tolerance (vSphere FT) becomes disabled during the snapshot process. If you use an ESXi host with an unsupported build, vSphere FT protection might become disabled during the snapshot process. This issue occurs because of an issue in earlier versions of the VMware ESXi host.

To back up virtual machines that are protected by vSphere FT with plug-in version 11.2 or later, your environment must use VMware ESXi 6.0 build number 4192238 or later. This issue occurs because of an issue in earlier versions of the VMware ESXi host. This issue is more likely to occur when the virtual machine uses Windows 2008 or later as the guest OS and it uses the VMware Tools VSS provider to take quiesced snapshots. For more information, see

Error using VVols with a storage array

If you use VMware Virtual Volumes (VVols) with a storage array that does not support thick-provisioned disks by default, you might receive the following error message: Error creating disk Error creating VVol Object. This may be due to insufficient available space on the datastore or the datastore’s inability to support the selected provisioning type.

To allow VVols to create thick-provisioned disks, enable thick provisioning on the storage array. For more information, see

Backup proxy opens in NBD mode instead of HotAdd transport mode

If you are using CentOS and Red Hat Enterprise Linux (RHEL) 6.x systems as the backup proxy, and the Primary Transport Mode is set to HotAdd or Auto and the Fallback Transport Mode is set to none, a VMware VDDK library prevents the backup proxy from opening the VM disk in HotAdd transport mode and causes it to open in NBD transport mode instead.
