Starting with AhsayOBM v9.1 and above, "Non-VDDK Backup Mode" VMware backups are no longer supported. Backup Set jobs created from older client agents, will fail.

If you are using VMware vSphere Hypervisor ESXi free license or require backup in Non-VDDK mode, you should remain with AhsayOBM v8.7 for continued support. If the device upgrades to AhsayOBM v9.1+, these backups will fail.
