I'd also like to point out that while it isn't "LAN free", depending on your 
vendor's terminology, snapvaults and snapmirrors may be more appropriate and 
can provide more functionality than a VTL. Plus since they are only backing up 
changed blocks, the data sent across the LAN is a lot less than a traditional 
backup. And as such can perform much faster.

-You really get great features like failover to a secondary site in the case of 
a disaster though.

Thanks for clearing that up.  I was wondering if VTL would be the way to go.  I 
will get more familiar with it.
