Are you backing up System State?  They changed how this works (I think in 
6.2.?), which puts more processing on the client side and allows server-side 
expiration to run more quickly.  I can confirm that the server-side expiration 
does indeed run much more quickly for System State backups.  We've not been 
able to quantitatively measure the impact on the client side.
