If you are using virtual IDE disk they are not supported:

This article has a few more useful things to check:

So, you've found the issue, IDE disk, not supported by Veeam. So you need to check if your disk is IDE.....

But no-one, is telling you want to do if you want to backup....

So now you will need to convert the IDE disk to SCSI, see this VMware KB

it's worth noting, SCSI disks are better, because they are faster, perform better, and also supported re-sizing, e.g. increasing which IDE do not.
