 ===== Cause =====
 <html>
-The VMware VDDK 7 API used in AhsayOBM v8.3.4.0 or above no longer supports backup in VDDK mode for VMware vCenter/ESXi v5.0 and v5.1
+This issue occurs because the VMware VDDK 7 API used in AhsayOBM version 8.3.4.0 - 8.3.6.125 are not supported by VMware vCenter / ESXi for backup in VDDK mode.

+===== Resolution =====
