Although this would not check the rdiff-backup sanity, it might get you an
idea about the rsync process: on both machines, cd to the rdiff-backup
repo and do
find . -type f -print0 | sort -z | xargs -0r md5sum > /tmp/md5sums
And then compare ( diff -u /tmp/md5sums /tmp/md5sums_from_other_machine )
these two files.
If you also have special devices in your repo, you could list those with
something like
find . -not -type f -print0 | sort -z | xargs -0r ls -l
But that would not be easily diffable I'm afraid.

Aside from that, a method to check sanity for increment X, or date Y,
would be nice. I think such a check would be even necessary before one
could properly implement a way to merge a number of increments.
Maybe I should get into learning Python to build such a feature.
