Description Jan Kratochvil 2008-02-04 19:30:12 UTC 
Description of problem:
During remote backup storage I would like to have locally only the signatures,
create incremental backup files locally and upload them myself (by rsync).
Fedora duplicity refuses it with:
  Found signatures but no corresponding backup files

Version-Release number of selected component (if applicable):
duplicity-0.4.3-1.fc8.x86_64

How reproducible:
Always.

Steps to Reproduce:
#! /bin/sh
set -ex
rm -rf signatures files backup1 backup2
mkdir signatures
mkdir files
echo file1 >files/file1
# No signatures found, switching to full backup.
duplicity --archive-dir ./signatures ./files file://$PWD/backup1
rm -f files/file1
echo file2 >files/file2
# Found signatures but no corresponding backup files
# vs.
# Warning, found signatures but no corresponding backup files
duplicity --archive-dir ./signatures ./files file://$PWD/backup2
echo OK

Actual results:
+ rm -rf signatures files backup1 backup2
+ mkdir signatures
+ mkdir files
+ echo file1
+ duplicity --archive-dir ./signatures ./files file:///tmp/duptest/backup1
No signatures found, switching to full backup.
./signatures/tmpGzdzb8 still in tempfile list, deleting
./signatures/tmp4nzsJ8 still in tempfile list, deleting

Additional info:
It works with the upstream version:
http://savannah.nongnu.org/download/duplicity/duplicity-0.4.9-0.fdr.6.src.rpm
The `Expected results' log was created with the upstream version.
Comment 1 Robert Scheck 2008-02-04 20:38:33 UTC 
Jan, 0.4.9 is a problem for me, because there were really HUGE changes which 
are causing also command line incompatibilities. Suggestions?
Comment 2 Jan Kratochvil 2008-02-04 20:47:00 UTC 
OK, fine to close with RAWHIDE and build the upstream version into Rawhide; F9
is pretty close.
Thanks for the serious care of the backward compatibility. :-)
