You dont need VMware Consolidated Backup. This was optional and only supported with VMware vSphere 4.1 and older.
Just download and install VMware Virtual Disk Development Kit (VDDK) and set the path for both VMware Virtual Disk Manager and VMware Disk Mount. VMware Virtual Disk Manager is required for backup operations (when job type is Backup-Image-SSH or Backup-Image-VADP) and for restore operations. VMware Disk Mount is only required for mounting hard disks in VM backups for file-level recovery.
VMware VDDK is a free API set from VMware. The version of VMware VDDK you need to download and install is determined by the utility using it, NOT the version of VMware vSphere you are running. The current version of Thinware vBackup supports VMware VDDK 5.1.4 and VMware VDDK 5.5.4.
VMware vCenter Converter Standalone is not needed either. Support for both VMware Consolidated Backup and VMware vCenter Converter Standalone have been removed in Thinware vBackup 5.0.
The best process for installing VDDK we have found is as follows:
1) Download and install VDDK 5.1.4 using all of the default settings. VDDK 5.1.4 will install to C:\Program Files (x86)\VMware\Virtual Disk Development Kit.
2) Download and unzip VDDK 5.5.4 to C:\Temp\VMware-vix-disklib-5.5.4-2454786.x86_64, then copy C:\Temp\VMware-vix-disklib-5.5.4-2454786.x86_64 to C:\Program Files\VMware.
3) In Thinware vBackup Client set the "VMware Virtual Disk Manager Application Directory" setting to: "C:\Program Files\VMware\VMware-vix-disklib-5.5.4-2454786.x86_64\bin", uncheck "Use same application directory for VMware Disk Mount" and set the "VMware Disk Mount Application Directory" setting to: "C:\Program Files (x86)\VMware\VMware Virtual Disk Development Kit\bin".
Hope this helps. Please let us know if we can be of further assistance.
