Smart update of cloned drive copies ~250K files
I have a Mac Pro with several internal drives to backup my main drive. Running Snow Leopard 10.6.1 with SD 2.6.1. I cloned my main drive to a erased backup drive earlier today. I recently closed all open applications, did a Smart Update, and 230,000 files out of 650,000 files were copied. I then immediately ran Smart Update again, and basically got the same number of files copied again (to within a few hundred files). I normally have SD running in the middle of the night so I have not monitored the behavior for a while, but this is not my recollection. I think repeat runs of Smart Update would copy a few 10's of files at most. Any thoughts?

For a possible explanation see "Some files get recopied every backup" in Dave's blog post:

Thank you. Makes sense. This appears to be performance, only, so I will wait for the next update to see if it is fixed. For my files, even though the number of files being copied is large, the actual size of the files is only ~3GB.
