I'm not sure what is intended, and I haven't looked at the code,
but --max-file-size=X behaves like "include files with size less
than X," which short-circuits on a match. Thus, it works with
rdiff-backup --exclude **.bak --max-file-size 134217728
But one is left wanting in many common situations, like yours. It
would be much more useful if it behaved like "exclude files with
size greater than X."
Well, "exclude files with size greater than X" is logically the same
as "include files with size less than or equal to X".
The problem is that rdiff-backup's selection logic supports only
include or exlucde (not ignore), and short-circuits. The short-
circuiting makes sense, but what is needed is ignore. With ignore
support, what you want is "ignore files with size less than or equal
to X, exclude files with size greater than X".
I'll add this use case to the IgnoreFiles suggested feature on the Wiki:
