Disappearing disk space

[Severin Crisp]

I notice, as time goes on, that, despite reboots and all the usual  
good housekeeping chores being performed that the available space on  
my boot disk (20GB) is slowly reduced.  Get Info shows that 10.54GB  
is used.  As part of my backup strategy I periodically mirror this  
drive to a 20GB partition on another disk using SuperDuper.  After a  
recent update, Get Info for this partition shows only 9.6GB used.  Is  
tthe significant difference just a fragmentation issue?   Do I dare  
to update the mirror, initialise the boot disk then mirror the mirror  
back again?  Hopefully I would then regain this space.   With a  
larger drive the problem would not matter, at times things get a  
little cramped with just 20GB and the lost 1GB would be worth  
recovering.
Comments please.
