Notes:
(1) VMware has reported an issue with ESXi version 6.0.x where incorrect changed sectors are returned. When a virtual machine (VM) is running ESXi 6.0.x and Changed Block Tracking (CBT) is enabled, some change areas in data are not reported. When this occurs, that data is not recognized as changed and is not backed up; current and past incremental backups are potentially compromised. For more information, see the VMware knowledgebase solution Backing up a Changed Block Tracking enabled virtual machine in ESXi 6.0.x returns incorrect changed sectors (2136854). This issue is resolved in VMware ESXi 6.0 patch ESXi600-201511001. For more information, see VMware ESXi 6.0, Patch Release ESXi600-201511001 (2137545).

(2) Microsoft does not support running Windows Server 2008/2008 R2 on Hyper-V Gen 2 VMs. Therefore, Windows Server 2008/2008 R2 physical machines with UEFI cannot be restored to Hyper-V.

Guest Virtual Machines

TypeSpecificationRequirements
VMwareVirtual Hardware
  • All types and versions of virtual hardware supported, including 62 TB VMDK.
  • VMs with disks engaged in SCSI bus sharing are not supported, because VMware does not support snapshotting such VMs.
  • RDM virtual disks in physical mode, independent disks, and disks connected via in-guest iSCSI initiator not supported and skipped from processing automatically. Network shares and mount points targeted to 3rd party storage devices are also skipped as these volumes/disks are not visible in the VM configuration file.
 Operating Systems
  • All operating systems supported by VMware.
 Software
  • VMware Tools (optional, recommended). VMware Tools required for the following operations: application-aware processing (quiesce).
  • All latest OS service packs and patches (required for application-aware processing).
Hyper-VVirtual Hardware
  • Supported virtual hardware versions 5.0 and 8.0 (Hyper-V 2016).

  • Both Generation 1 and 2 VMs supported, including 64 TB VHDX disks.

  • [For Microsoft Hyper-V 2016 Server VMs] Processing of VMs with pass-through virtual disks and disks connected via in-guest iSCSI initiator not supported.

  • [For Microsoft Hyper-V 2012 R2 server and earlier VMs] Pass-through virtual disks and disks connected via in-guest iSCSI initiator not supported and skipped from processing automatically.

 Operating Systems
  • All operating systems supported by Hyper-V.
 Software
  • Hyper-V integration components (required for application-aware processing)
