Something else might be wrong with my system. After a few days of running normal backups, a small backup of nightly log data is now crashing mono/duplicati entirely. I’ve restarted it 4 times this morning - same results each time:

Each time I restart Duplicati, it continues the same backup operation where it left off - “Deleting unwanted files”. How do I break the cycle? I’ll confess that I haven’t run backups from the command line much, always use the web interface.
