duplicity and crontab
 
|
Hello to all, I have made a shell script to perform a backup with duplicity, the script works well if I run it from xterm. However, when I try to run the script with cron for automatising the backup something does not work with duplicity. I looked in the web but it is not clear what is the way out. Has anyone succeeded to do this?

One other thing to check: Cron jobs run as root by default. You'll need to check that duplicity has access to ~root/.gnupg and that your keys are there. ...Ken On Fri, Nov 6, 2020 at 6:19 AM edgar.soldin--- via Duplicity-talk <[hidden email]> wrote: On 11/6/2020 12:45, Giuliano Franchetti via Duplicity-talk wrote: _______________________________________________ Duplicity-talk mailing list [hidden email] https://lists.nongnu.org/mailman/listinfo/duplicity-talk |

unless they are user cronjobs of course ;) set up via 'crontab -e' in user context.
but Ken is right. often users edit crontabs under /etc and the wonder why duplicity using key enc does not work while it did in their user's shell. the above is a common pitfall. .ede/duply.net On 06.11.2020 16:33, Kenneth Loafman via Duplicity-talk wrote: > One other thing to check: Cron jobs run as root by default.

In reply to this post by duplicity-talk mailing list
Cron jobs run with a reduced
environment in comparison to your standard bash shell. e.g. I
think they actually run with sh rather than a full bash. But
definitely with a minimal PATH environment. So you will probably
want to include a PATH directive in your shell script. Simply copy
the output of:
env | grep PATH into your shell script. Put that line before you run any actual shell comands in your script. It might also help if you include a bash header in your script, e.g. #!/usr/bin/env bash or something like that. You could also include a "pipe to logfile" option in your crontab entry, e.g.: 00 02 * * * /command/to/run.sh > logfile.log On 06.11.20 12:45, Giuliano Franchetti
