Decided to use rsync, and have a question...

Why, after rsync'ing /usr to /tmp-usr, do the sizes differ?

  # du -h --max-depth=0 /usr
3.5G    /usr


  # du -h --max-depth=0 /tmp-usr
3.7G    /tmp-usr

Is that because of the different filesystems (ext4 on / and reiserfs on 
/usr) maybe?

Is there a simple way to get the total # of files and directories for 
comparison, like you can in Windows when getting properties of a folder?


Best regards,
