VCB will only work with either a Fibre Chanel or iSCSI SAN. This is why vRanger is only doing network backups.
VCB will also work with network backups if the -m nbd option is given, but I do not think vRanger does that.

If network backups are not supported for VCB, we'll have to look at other possibilities.
no you didn´t read carefully;) - vcb CAN do network backups since the latest update! but we think vizioncore has not implemented that new feature yet.
I did read it correctly it's just that we need a backup solution, like yesterday!
I know I am late to the game, but I too have the same question, mostly. I have an 8 ESX farm using iSCSI for VM backend storage. I am currently backing them up with VCB and vRanger Pro. Works like a champ (esx 3.5u1). I am now creating a new ESX farm (3.5u3) which will use NFS for VM storage.
I have heard many things (many contradicting from Vizioncore themselves!), but ultimately, yes vRanger Pro will backup NFS stored VMs and utilizing VCB. I am waiting for v3.2.9 (3/9/09?) before moving forward, but one representative wanted to do some fnacy mounting scheme on the ESX host itself and another is suggesting using tghe "-nbd" option but have the data pass through the service console.
Does this make sense? Anyway to mount the NFS shares on my VCB proxy server (physical box) like it does for the iSCSI luns to keep the service console out of the picture? If that can be answered (positively), then I would be estatic.
The only real reason to use VCB with vRanger is to leverage the virtual LUN driver that mounts the VMFS. This is only good for FC or iSCSI SANs. You are better off just using vRanger without VCB if you have NFS storage. IT still goes through the COS network.
If you do not want the load on the COS network, then you have a couple of choices:
Investigate using VCB in "Hot-Add" mode as a stand-alone VM. I have not tried installing vRanger in this mode, but it should work in theory...
add an ESX server that is not in the DRS/HA cluster, but mounts the VMFS store
