I have a problem with my backup cronjob. I use these settings (as proposed in that post):
15 * * * * env DISPLAY=:0 /usr/bin/deja-dup --backup
During runtime deja-dup says:
Backup location not available. Waiting for 'xy' to become connected...
The external disk 'xy' is mounted; I can also create a backup when I run deja-dup --backup in the command line.
Any ideas what the problem could be? Could it be a permission issue? But crontab runs the job with my user I suppose.
