NetVault Plug-in for VMware 13.2.1 - User Guide

Disk type is always Thick Provision Eager Zeroed after restoring an image-level backup

After restoring a virtual machine, virtual drives that are Thin Provisioned or Thick Provisioned Lazy Zeroed are automatically converted to Thick Provision Eager Zeroed.

Regardless of the disk provisioning type, image-level backups without CBT enabled always back up the full disk. During restore, the “.vmdk” file is completely overwritten and VMware automatically converts a Thin Provision or Thick Provision Lazy Zeroed drive to Thick Provision Eager Zeroed.

To retain the original type for the drive during the restore process, make sure that the Enable Change Block Tracking for virtual machine option is enabled for the backup job. For more information, see Defining a backup strategy.

Backup jobs of virtual machines protected by vSphere FT fail intermittently

When backing up virtual machines that are protected using VMware vSphere Fault Tolerance (vSphere FT), the backup job fails.

The job fails and reports the following: Cannot back up virtual machine while legacy fault tolerance is enabled.

CAUTION: Before using the plug-in to back up virtual machines that are protected using vSphere FT, verify that your environment uses VMware ESXi 6.0 build number 4192238 or later.

Your virtual machine is protected by an earlier version of fault tolerance that does not support backup snapshots.

To back up and restore virtual machines that are using legacy fault tolerance, reconfigure the virtual machines to use a newer version of vSphere FT. Using the vSphere Web Client, turn off fault tolerance for the virtual machine, and then turn it on again. During the reconfiguration process, FT protection is not available for the virtual machine that you are reconfiguring.

RDM disks are restored to VMDK files

RDM disks in virtual compatibility mode are restored to flat “.vmdk” files and not to the original RDM.

The alternative is to omit these disks during a restore.

Unable to consolidate image-level backups

When you use the NetVault Plug-in for Consolidation, the image-level backups of virtual machines are displayed on the Create Selection Set page, but you cannot consolidate these savesets.
