One slight error concerning Litespeed, there is a ( free ) utility which allows you to restore a litespeed backup on a a non litespeed server.

If you forget the GUI , I never make use of the gui for handling production backups anyway, and use the extended procs with scripts/procs then Litespeed is a dream to use.

The reality is that Litespeed does live up to the hype - a well recommended product - I wouldn't leave home without it
