| - | We have recently confirmed a critical issue related to VMware virtual machine backups on **all VMware Workstation and some VMware ESXi backup sets**, which occurs when the guest VM is created with the VMDK file that are split into individual 2GB VMDK files. | + | We have recently confirmed a critical issue related to VMware virtual machine backups on **all VMware Workstation and some VMware ESXi backup sets**. |
| + | |||
| + | This issue only affects guest VMs created using the option **Split virtual disk into multiple files**, which causes the VMware host to create multiple VMDK files up to 2GB each as the guest VM grows. //Example setting for VMware Workstation 12.0// | ||

| Due to this bug, AhsayOBM is unable to fully retrieve the correct number of 2GB VMDK files for the guest VM, which causes the backup job to miss some of these 2GB VMDK files. Even though AhsayOBM reports the backup job is successful the guest VM is no longer recoverable. | Due to this bug, AhsayOBM is unable to fully retrieve the correct number of 2GB VMDK files for the guest VM, which causes the backup job to miss some of these 2GB VMDK files.
