See https://www-secure.symantec.com/connect/forums/what-virtual-tape-library 
and https://www-secure.symantec.com/connect/forums/vtl-0

There is more but I think the above 2 posts explain it well enough.

My personal opinion about VTLs can be seen in the 2nd URL:

The only reason why VTL was developed, was because no backup software could address disk as backup device in an efficient and intelligent manner.

NBU introduced Advanced Disk and OST in version 6.5.

Since then, I personally see no use for VTL.
