[rdiff-backup-users] Deleting remote folders

[Josh Nisly]

I'm trying to implement support for removing a failed initial update. 
One of the things that I need to do is remove the increments directory. 
When I try to do this over a remote connection, the server throws a 
security violation exception. However, we obviously need to delete 
remote directories during the backup (we actually create and delete on 
in fs_abilities.py).

Any ideas on what I can do to be able to delete this directory?

Thanks,
