Daniel, I'm still unsure what you are talking about.
There is Image level backup (VMDK)
There is Guest level backup (Traditional agent in guest)
You keep referring to file level backup?
VCB is dead. Let's make that point clear. vStorage is the replacement (for
most backup vendors).
With
What do you mean File level backups?
There is either image level (entire VMDK) or guest level (agent within guest)
Which NBU can do both, among many other backup vendors.
VCB is so last year. the new vStorage API's can use Change Block tracking
(CBT) so you dont have to send the entire VMDK
