Yes, anything is possible, but if you are restoring a system state, it is 
probably because your system is broken, and most likely you want it up as 
soon as possible, which means that you don't want to be rewinding and 
re-reading media.  If it is several volumes and part of the data is at the 
end of a Volume, it can take a very long time to get to the end of an LTO-4 
volume when you want your machine running right away.  This technique may get 
the job done, but it is not suitable for most enterprises.
