With backuppc the issue is not so much fragmentation within a file as 
the distance between the directory entry, the inode, and the file 
content.  When creating a new file, filesystems generally attempt to 
allocate these close to each other, but when you link an existing file 
into a new directory, that obviously can't be done so you end up with a 
lot of long seeks when you try to traverse directories picking up the 
inode info.
