Over here in the Amanda project, we get users *all the time* who are confused 
why other files in the directory structure they just restored to have 
suddenly been blown away. IMNSHO it would be better if the incremental 
restore works analogously to the non-incremental restore: That is, to not 
delete stuff not mentioned in the archive.

You should also consider the possibility that the archive has been created 
with exclude options, which presumably should be excluded from deletion at 
restore, as well.
