I am using luckyBackup 0.4.8 on Kubuntu 15.04. I created a profile to backup my data files. When executing the profile manually everything works fine.
I also created a cron schedule to execute the backup automatically. The log file "/root/.luckyBackup/logs/-LastCronLog.log" is updated at the right time so obviously cron works correctly.
However new files are not copied so the backup itself does not work.
The log files named like "--20151107205001.log" (in the same folder) are NOT updated at the same date/time and were updated during manual execution last time.
In the "-LastCronLog.log" I can see some error "No protocol specified luckybackup: cannot connect to X server :0".
How can I make the backup work?
