-When performing a VMware guest VM backup in VDDK mode on VMware vCenter / ESXi version 5.0.x, 5.1.x, or 5.5.x, the following error message is received in the backup report:  +</html>
- +
-^ No. ^  Type ^ Timestamp ^ Log ^ +
-| * | info | ...| ... | +
-| * | erro | YYYY/MM/DD hh:mm:ss | Fail to connect VM disk by VDDK library " error: "VDDK Mode Error Virtual Machine = "​VM/​Hard disk" Reason = "Fail to connect VM disk by VDDK library"​. Error=Unknown |  +
-| * | ... | ... | ... |  +
- +
-===== Cause =====  +
- +
-This issue occurs because the VMware VDDK 7 API used in CloudBacko Pro v4.1 or above, are not supported by VMware vCenter / ESXi version 5.0.x, v5.1.x, and v5.5.x for backup in VDDK mode. +
- +
-===== Resolution =====  +
- +
-To workaround this issue, replace the current VDDK 7 API with the VDDK 6 API files, [[https://​download.ahsay.com/​support/​vddk6.zip|Click Here]] to download the VDDK v6 API files. Refer to the following steps to replace the files: +
- +
-  * Stop the CloudBacko Pro service. +
- +
-  * Stop the CloudBacko Pro NFS service. +
- +
-  * In Windows Explorer, make a copy of the current folder %CBP_Install_home%\bin\x64. +
- +
-  * Open the folder %CBP_Install_home\bin\x64. +
- +
-  * Delete the following .dll files (13 files in total): +
- +
-<WRAP indent>​ +
-    * diskLibPlugin.dll +
-    * libexpat.dll +
-    * lookup-types.dll +
-    * msvcp120.dll +
-    * msvcr120.dll +
-    * pcre.dll +
-    * sqlite3.dll +
-    * ssoclient.dll +
-    * vddkVimAccess.dll +
-    * vim-types.dll +
-    * vmacore.dll +
-    * vmomi.dll +
-    * zlib1.dll +
-</WRAP>+
  
-  * Unzip the downloaded vddk.zip file and copy its contents to the %CBP_Install_home%\bin\x64 folder. 
  
-  * Restart ​the CloudBacko Pro service.+===== Cause ===== 
 +This issue can occur if the guest virtual machine was originally backed up from a VMware ESXi host with a datastore of a different VMFS version. 
  
-  * Restart ​the CloudBacko Pro NFS service.+For example, ​the backup of the virtual machine was done on a VMWare ESXi host with a VMFS5 datastore in VDDK backup mode, but the user is not attempting to restore the virtual machine to another VMware ESXi host using a VMFS6 datastore, and vice versa.  
  
 <WRAP important>​ <WRAP important>​
-After replacing the VDDK 7 API files with the VDDK 6 API files, CloudBacko Pro v4.1 or above can no longer support backup of VMware vCenter ​/ ESXi v7 backup sets.  Please replace the files at your own discretion.+This limitation does not apply to VMware vCenter backup sets.
 </​WRAP>​ </​WRAP>​
  
-Here is the list of VDDK 6 API files (17 files in total): 
  
-  * glib-2.0.dll +===== Resolution ===== 
-  * gobject-2.0.dll +Unfortunately,​ there is no workaround for this issue. &​nbsp;​You can only restore to the corresponding guest virtual machine to a VMware ESXi host with datastore that is using the same VMFS version.
-  * gthread-2.0.dll +
-  * gvmomi.dll +
-  * iconv.dll +
-  * intl.dll +
-  * libcurl.dll +
-  * libeay32.dll +
-  * liblber.dll +
-  * libldap.dll +
-  * libldap_r.dll +
-  * libxml2.dll +
-  * ssleay32.dll +
-  * VddkJNI.dll +
-  * vixDiskLib.dll +
-  * vixDiskLibVim.dll +
-  * vixMntapi.dll+
