But why is this happening? What is the difference between Windows and
Linux that would cause this?

As I said in my post, this problem is easiest to see on the dual-boot
machine, however it also is apparent on other machines.
Here is the backup listing for a Windows machine, where you can see that
the number of files transferred after the first backup is quite small:
Totals Existing Files New Files
Backup# Type #Files Size/MB MB/sec #Files Size/MB #Files Size/MB
0 full 800 676.7 2.23 87 47.4 795 629.3
1 incr 5 34.9 0.94 2 9.2 21 25.7
2 incr 5 34.9 1.20 2 3.0 8 31.9
3 incr 5 34.9 0.85 6 34.9 0 0.0
4 incr 11 35.4 0.96 4 19.3 17 16.0
5 incr 11 35.4 0.47 12 35.4 0 0.0
6 incr 11 35.4 0.91 12 35.4 0 0.0
7 incr 11 35.4 1.41 12 35.4 0 0.0
Here is the backup listing for a Linux machine, where the incrementals
are getting bigger and bigger each time:
Totals Existing Files New Files

Nope, it's NTFS on Windows, ReiserFS on Linux.
