It is useful for all those systems, where you don't have python 2.2
and librsync on your local machines, just a way to bring data to a
common backupserver, that has everything needed installed.
I don't think that it's only the case for me...
But I agree that it is a security problem. The possibility to ruin your
backup is always a problem. In the link you send me, this problem is
solved in an elegant way.
As it seems, that you don't like the idea, I will have to implement it
myself. Shall I send you patches that you have it (at least as undocumented
feature) and I can more easily incooperate rdiff-backup updates?

So, what fraction "mirror files"/"increment files"?
