I've been trying to get my head around virtual full backups.

Now, from my understanding, (i'm 80% through my work day, shut down 20 
tickets, and had to deal with too many user incidents for my liking, so 
please bare with me if I say something stupid!), virtual fulls can be 
run on the same pool as a real 'recent' full has been run on, and it 
will create a new full based on all the latest files still in the pool. 
It then takes these files, and only take the latest changed files, from 
the client to create a new usable full backup, which should pretty much 
take the same time as between and incremental and a differential.

If this is the case, then I can slash my backup times, from 5 hours per 
host, to around 20 minutes, which is something I think would be pretty 
frikkin' awesome! Feel free to comment, and suggest :)
