This is not simple at all. This is not part of the rdiff-backup spec.
rdiff-backup is meant to backup the same directory every time. Of
course, files are created, modified, deleted, and excluded, and
subdirectories are created and removed, but the overall content is
supposed to remain constant.
Moroever, the rdiffs are for individual files, not for whole directories.
There is a directory tree structure that includes files inside each of 1001, 1002, ..., 100N. It is largely similar between each of 1001, ..., 100N. Therefore, backing up the contents inside these directories into one constant location on the destination would fit rdiff-backup's feature set extremely well I would think.

You don't, at least not without hackery.
OK, thanks. Your explanations were very helpful.
