I have an old vmware setup i was trying to backup with Veeam 8. It threw a warning saying the vmdk has been skipped due to unsupported type Independent.

When a disk in independent persistent mode, it means no delta file can be created and thus nothing can be written to the disk.  This is by design and refer to link below for a good explanation:

basically it means it cannot create a snapshot of the virtual disk, and hence will not be able to back it up.

Power off the VM, and in the disk VM Properties, change from its current setting which is wrong.

To change a disk to persistent:
Power off the virtual machine.
Click Edit Virtual Machine Settings.
Select the Hard Disk.
Uncheck the Independent Mode field.
Click OK.

Andrew, is there any risk of data loss by performing this change?
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
You need to check, what the setting is, and whether you currently have any snapshots attached.
Cobra25Author Commented:
It turns out it is an independent disk...now what?
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
Is it Independent - Persistent or Independent - Nonpersistent ?

Uncheck the Independent Mode field.

and then you will be able to backup using Veeam.

The C: drive has independent mode UNCHECKMARKED
My D: drive on the server does have Independent - Persistent checkmarked
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
Just untick Independent for the D: drive.

Is there any impact by changing to independent?
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
No, other than you'll be able to create snapshots, and it will fix backups for you.
