ISSUE: Delta disk format of virtual disks is not supported by datastore (VMware ESXi restore)
Article ID: 8080
Reviewed: 22/04/2020
Product Version: CloudBacko Pro: 4.1 or above
OS: Windows
Problem Description
When performing a guest VM restore on a VMware ESXi host, the following warning message is received, and the guest VM is not restored:
| No. | Type | Timestamp | Log |
| * | info | ... | ... |
| * | warn | YYYY/MM/DD hh:mm:ss | "Delta disk format of virtual disks is not supported by datastore." |
| * | ... | ... | ... |
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.
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.
Important: This limitation does not apply to VMware vCenter backup sets.
Resolution
Unfortunately, there is no workaround for this issue. You can only restore to the corresponding guest virtual machine to a VMware ESXi host with datastore that is using the same VMFS version.
