I am having an issue, that I can't seem to get around.
  
I have 2  DNS-343 that I would like to have rysnc'd.   The primary device (NASPrimary) is running stock firmware 1.03.   The second (NASBackup) is running Firmware 1.03, and is using fun_plug .05.    The fun_plug is running I have been able to telnet no issues.
I have created an editcron.sh file for the /ffp/start  (and have copied and paste the script from the web)
I have placed my rsync script (NASbackup.sh) in /ffp/tmp   
When I run the editcron.sh it executes everything fine.  crontab -l lists my entry correctly, and triggers at the time required.
The Problem:
When I reboot the backup device (NASBackup), if I log in as soon as the IP address is displayed on the device  crontab -l shows my entry,  a few moments later (approx 1 minute)  crontab -l is back to the stock setup.    Is there anything I am missing, or what is overriding my crontab list after boot??
Thanks,
Wayne
