[Duplicity-talk] file restore failure?!

[C.Enzmann]

Howdy.

I have working backup with ssh/scp on duplicity 0.7.10 like

Number of contained backup sets: 2
Total number of contained volumes: 2
 Type of backup set:                            Time:      Num volumes:
                Full         Sun Dec  4 10:36:14 2016                 1
         Incremental         Sun Dec  4 10:43:21 2016                 1

I back up a test directory /home/me/bkp_root there. Deleting the whole
directory /home/me/bkp_root and restoring it: fine.

Deleting a file, I need to use "duplicity verify --compare-data" ... to
see a difference at all - but ok, it shows missing. 

But worse with 'duplicity restore --use-agent
--ssh-options="-oIdentityFile=/xyz/id_duplicity" --name=myhost
scp://address@hidden:port/BackUps/'
and anywhere any combination of '/home/me/bkp_root' and
'--file-to-restore subdir/file', with absolute or relative paths, not to
mention with wildcards, and in any order I get either
"Restore destination directory already exists. Will not overwrite."
        -or-
"Command line error: restore option incompatible with inc backup."

Please, could I kindly ask for enlightenment, before I may start to rant
that a reasonable partial restore is essential but impossible that way
and calling names to this tool and yadda yadda.

Many thanks in advance & kind regards,
Chris
