I'm running Duplicity for backup of my desktop to a remote storage. Everything has been working fine, but now I see in my log that Duplicity has been exiting with exit status 23 for a couple of runs. As of what I can see the backups are running and the backups are uploaded to the remote computer.

The exit status 23 seems to only happen when it's run in the background as a cron-job. When I run the backup script manually I get a 0 exit status.

Duplicity's man page lacks info on the meanings of the programs exit statuses, so I don't really know where to start.

cat syslog.1 outputs:


Jan 23 12:54:35 xx anacron[998]: Job `cron.daily' started

    What's the error output from cron? (It's probably being emailed to your local user account.) – roaima Jan 22 at 21:51
  • @Christopher, Interesting, could you cite the source for that? – PetaspeedBeaver Jan 23 at 11:59
  • @roaima Good point! Will look into that! – PetaspeedBeaver Jan 24 at 19:37

    I now have the exact same issue, after having the cron script run for 3 years. So thanks for closing the question guys, I doubt I would have rephrased it much differently than the OP. Oh, and this is the nr. 1 result on Google for "Duplicity error 23". This could have been helpful. – zmippie May 12 at 6:37
  • @zmippie this question appears to have been abandoned. Within a day of it being posted I asked for additional information, but none came. I'd suggest you post a new question with at least the amount of detail here (including error output from cron please), and flag this dead question here as a duplicate of your new one. (Flag with a moderator if you can't actually mark it as a dup.) – roaima May 14 at 7:49
