I did have an idea earlier. One thing I noticed is that during the
original backup I had a restart. I wonder if the restart/resume logic
is somehow corrupting the signature files?
This is the problem. I was able to reproduce it when there is a RESTART.
Summary: When a RESTART occurs, all files prior to the restart will be
marked deleted and re-backed up in subsequent backups
To reproduce:
1) Kick off a full backup. Wait until several volumes have been uploaded
and then hit Ctrl-C during the upload of a volume. You will probably
have to hit Ctrl-C five times to abort each of the five retry attempts.
The goal is to exit back to the shell.
2) Run the same backup command and let it complete. Duplicity will print
something like
"RESTART: Volumes 2 to 3 failed to upload before termination.
Restarting backup at volume 2."
At this point you are supposed to have a completed full backup set.
3) Run the same backup command and let it complete. This will be your
first incremental. All files located in volumes prior to the RESTART
will be marked as deleted.
4) Run the same backup command and let it complete. This will be your
second incremental. All files marked deleted will be backed up again and
marked deleted again.
If you still want me to upload to pastebin I can, but this should allow
for reproduction of the problem.
