VMware vSphere does not remove snapshot delta disks during restore


When you restore a backup of a VM on a Windows 2008 or Windows 2008 R2 system, SnapCenter Plug-in for VMware vSphere does not always remove all snapshot delta disks.

During a backup, SnapCenter Plug-in for VMware vSphere creates the quiesced VMware snapshot, which results in the creation of snapshot delta disks. However, if you restore the VM, revert to the VMware snapshot taken during the backup process, and then delete it, not all the delta disk files are deleted.

Corrective action

There is no workaround for this issue. You might want to contact VMware support for assistance.
