NetVault Plug-in for VMware 13.1.2 - User Guide

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.

Restore job fails on Linux when file size exceeds 50 MB

To avoid file fragmentation, the Plug‑in for VMware preallocates disk space before restoring files to disk. On Linux-based systems, files that are larger than 50 MB in size are not pre‑allocated full disk space. Such files are handled similar to sparse files and allocated disk space as needed during restore. If the disk does not have sufficient space to fully restore files that are larger than 50 MB in size, the job fails when the disk runs out of space.
