Not directly. I think there are other third party components out
there that can do this for you but dont have links to any but my own:

This is NOT a gbak style backup and so may not be what you are looking
for.

You could also write your own using the same services API that IBX
uses - but could be some hard work :-)
Also, AFAIK there is no reason why you cannot use that feature of IBX
while still using IBO for normal access.
