Multiple processes are started

When I start a backup via cron or manually, it runns smoothly for quite some time.

--- RBK0009I: orangepipc: raspiBackup.sh V0.6.1.3b um Sun Feb 5 20:48:25 CET 2017 gestartet

After a while, a new backup is started every minute.

This is the command executed: /usr/local/bin/raspiBackup.sh -t tar -e email@tld.de -k 30 -z -n /mnt/BackupNas &> /dev/null
I am running an OrangePi PC with Armbian.

A similar issue was already reported some time ago by a user of raspiBackup. Actually raspiBackup has no means to guarantee it's executed only once. I will add this check in the next version now.
The root cause was a misconfigured crontab entry which kicked off raspiBackup every 5 minutes.

/usr/local/bin/raspiBackup.sh -t tar -e email@tld.de -k 30 -z -n /mnt/BackupNas &> /dev/null seems to be part of your crontab. Please check this entry.

You are right! How could I miss that one :-(
Thank you.

Great you fixed it now :-) Just added code in the next version 0.6.1.4 which will write an error message if raspiBackup is started when it's already up and running
