[Duplicity-talk] Getting started with duplicity.

[Bill Broadley]

I installed duplicity on two ubuntu 6.10 boxes, foo and bar:
address@hidden:~$ /usr/bin/duplicity -V
duplicity 0.4.2
address@hidden:~$ /usr/bin/duplicity -V
duplicity 0.4.2

Man page mentions:
 duplicity /home/me scp://address@hidden/some_dir

So I made a test directory:
address@hidden:~$ mkdir test; cd test; for i in a b c d e; do dd if=/dev/urandom 
of=$i bs=1024 count=1024; done
address@hidden:~$ ls -lh test
total 5.1M
-rw-r--r-- 1 bill bill 1.0M 2007-02-21 11:06 a
-rw-r--r-- 1 bill bill 1.0M 2007-02-21 11:06 b
-rw-r--r-- 1 bill bill 1.0M 2007-02-21 11:06 c
-rw-r--r-- 1 bill bill 1.0M 2007-02-21 11:06 d
-rw-r--r-- 1 bill bill 1.0M 2007-02-21 11:06 e

So I tried:
address@hidden:~$ /usr/bin/duplicity -v5 ~/test  
scp://address@hidden//home/bill/backup
Reading results of 'echo -e 'cd /home/bill/backup
ls -1' | sftp -b - address@hidden'
Invalid command.

When I run it again I get similar output, always a full backup.

The invalid command is puzzling, if I run it manually:
address@hidden:~$ echo -e 'cd /home/bill/backup
> ls -1' | sftp -b - address@hidden
sftp> cd /home/bill/backup
sftp> ls -1

Any idea on the invalid commands and/or the reason that every backup
is a full backup?
