At the moment, no image-level backup solution supports fault tolerance, because VMware does not support creating snapshots on such VMs, which is a requirement for image-level VMware backup. vStorage API for Data Protection can only work with snapshots (its functions require passing snapshot ID as mandatory parameter). Thanks!

VMware FT has still two main problems (where VMware is working on):
a) it can have only one single vcpu, b) it cannot have any snapshot.
The only way to really backup a FT enabled vm is to backup it with some imaging tool (for example drive snapshot by tom ehlert) from within the guest or if using newer windows servers you could use windows backup to create a bare level somewhere to the network.
I was just told from your support that I cannot use VB to backup FT-enabled vm:s even if the vm:s have FT disabled. Why is this ? Vmware suggests to temporarily disable FT when I, for instance, want to clone a FT protected vm. So why haven´t you made it possible ?
