[Duplicity-talk] "full-if-older-than" not working?

[Scott Hannahs]

Duplicity 2.1.3 / MacOS 13.6

Duplicity seems to be working and backing up incremental fixes.  However I was 
trying to force a new full backup by reducing the time to trigger a full 
backup.  The incremental backup seems to be working (at least for the last 3 
days now that I rebuilt duplicity).  Note the "--full-if-older-than 1D” flag 
which should be triggered since the last full backup was 9/23/2023.  After 
updating requests all those warnings about version mismatch went away.

Here is the command line I used:
nice -n19 /opt/sw/bin/duplicity backup --full-if-older-than 1D --num-retries 5 
--tempdir /var/tmp/duplicity --volsize 500 --encrypt-key ZZZZZ --sign-key 
WWWWW --gpg-binary /opt/sw/bin/gpg --gpg-options=--default-key=VVVVVV --force 
--verbosity Notice --allow-source-mismatch

Local and Remote metadata are synchronized, no sync needed.

And here is the status report for the repository.  It seems to me that the last 
full backup was certainly longer than 1 day.
Found primary backup chain with matching signature chain:
