Dunno :)

I can't picture why you're doing the cp stage. I'm using rsync to copy  
into a fresh directory for each backup and telling it to compare the  
new copy to the previous day's backup and make a hard link to any  
files that are unchanged. The --link-dest switch to rsync is the key  
to that.

As a result I have complete daily snapshots of my server for the last  
month and then monthly snapshots back to the beginning of backup  
history.
