This is a frequent question.  The answer is: no such statistic exists.  A host 
does not use a given amount of space at all.  All files are pooled, and one 
cannot say how much of the pool a specific host uses, because there is overlap. 
 
Only the storage/transfer statistics per backup are relevant.

You could total up the transfer statistics for a rough guess, but again it 
ignores pooling.

What problem are you trying to solve with this question?  Your pool is too big 
and you want to know which host should have fewer backups to reduce it?
