Backup operation not supported by backend

[Loren41]

Trying to run Deja Dup backup but operation fails. Message is "Backup Failed. Operation not supported by backend." Directing output via Samba to a server on my home network. Backups were working earlier but I must have changed something. Need help.
Prefer GUI solutions when possible.

Can you please provide some information:

1. The distribution of Linux you're using:
    lsb_release -d

2. The version of deja-dup and duplicity:
    (if on Ubuntu or Debian:)
    dpkg-query -W deja-dup duplicity

    (if on Fedora or other RPM-based systems:)
    rpm -q deja-dup duplicity

3. The file /tmp/deja-dup.gsettings after running the following line (you may want to scrub the file of any incriminating file names or details):
    gsettings list-recursively org.gnome.DejaDup > /tmp/deja-dup.gsettings

4. The file /tmp/deja-dup.log after running the appropriate line below and replicating the problem (you may want to scrub the log of any incriminating file names or details):

 * If you're having problems backing up:
    DEJA_DUP_DEBUG=1 deja-dup --backup | tail -n 1000 > /tmp/deja-dup.log

 * If you're having problems restoring:
    DEJA_DUP_DEBUG=1 deja-dup --restore | tail -n 1000 > /tmp/deja-dup.log

I seem to run into a similar situation. I have managed to create 4 automated back-ups last month and this month it simply stopped working. I have gone over my FTP settings but I can't find the problem, FTP works fine otherwise.

I keep receiving the error "Operation unsupported". Will include output as requested.

Last bit of the log where the errors start.

I upload from Ubuntu 13.04 to a Zyxel nsa310 NAS.

Hi, I get this with backap of ftp server, too. The bad thing is that there is no reason given, just "Operation unsupported".

I'm trying to backup to an internal FTP server and i'm getting the same error:

Hi all,

I've just switched to 14.04 from 12.04.
In the previous version I was doing backups to my FTP server.

Now I've got the same problem as other users:
