Using '*' you could miss directories and files starting with a dot.

Maybe a cat walking on the keyboard?

However this could be interesting too:

It seem's that the size of empty directory is file system dependant:
$ mkdir dir-on-xfs
$ mkdir dir-on-ext3
$ du -b dir-on-xfs
6	dir-on-xfs
$ stat dir-on-xfs | grep Size
Size: 6               Blocks: 0          IO Block: 4096   directory
$ du -b dir-on-ext3
4096	dir-on-ext3
$ stat dir-on-ext3 | grep Size
Size: 4096            Blocks: 8          IO Block: 4096   directory

So, if you want to check your backup, don't rely on du but use md5sum 
and/or sha1sum on the files.
