Ah, ok ;)

              When cleaning up, be more aggressive about saving space.  For 
example, this may delete signature files for old backup chains.  See the
              cleanup argument for more information.

I may be wrong, but this tends to indicate that it will cleanup most of
what might have been left around (signature files, etc.).

But does this really remove incremental backups on the target backup
space, only keeping their base full backups ?

Let me repeat my use case : 
        I cannot seem to find a set of duplicity options that would
        allow me to keep only full (monthly) backups, if I were to use
        incremental --full-if-older-than 30D".
I imagined this --extra-clean option was just a kind of rm -f on all
hidden files instead of rm or regular files, and not a specific removal
of only incremental backup files (to take an analogy to unix filesystem)

Maybe the docs should be improved to make this more explicit ?

Thanks in advance.
