Do you mean it grew on the destination system between immediately before 
the rsync and immediately after? I that case I would guess that somebody 
added 360G of files in the mean time, or has been using sparse files.

Or do you mean that it was 540G on the old system and 907G on the new? In 
that case I'd guess a difference in filesystem or in cluster size of the 
filesystem.

Cheers, Chris.
