I have installed Duplicati on Qnap with the help of the package from Qnapclub. This went fine for the first few weeks. But recently i have a problem with Duplicati stopping randomly. The web frontend isn’t accessible, there are no processes called duplicati running. Executing /opt/Duplicati/Duplicati.sh start results in Duplicati starting up fine and proceeding its tasks - for around 4-5 hours. Problem is further: the /opt/Duplicati/duplicati.log has no recent entries. I tried to delete it - it got successfully recreated at the next start, but it is completely empty.
I have no clue why Duplicati stops, and also have no clue why the log file is re-created, but completely empty. However, a backup service stopping at random is not very good, so i am asking for help. Has anyone an Idea what could causing these stops/crashes?
