[Duplicity-talk] Backup failing (ftp, error 553)

[duplicityml]

Per Subject.

What I am doing is
  duplicity --verbosity info --encrypt-sign-key=$GPG_KEY --log-file backup.log 
~/Pictures/MyStuff ftp://foo:<SECRET!>@ftpserver//foo/MyStuff
and I then get some good data sent (and can see them on the ftp server):

if that helps.

I don't understand why it should suddenly fail part way through. It now won't 
do anything at all (same error). Nothing changed on the ftp server 
configuration-wise (I can be sure of that because I'm the only one who has 
access and it's right there /points to the box, the other side of the room).

Can anyone help, please?
