I have been running a work unit (BBC project) for over 2100 hours. It was just over 50% completed. Yesterday, I suffered a power outage. The work unit has started over from the beginning. There were no error messages I could see. Over the past 85 days I have uploaded 5 or 6 large ZIP files, so it would seem partial results have been preserved.

Can anything be done other than me running the work unit again for almost 90 days to get back to where I was? That seems such a waste.

Bad luck on the power outage. I\'ve been lucky on each of the several that I\'ve had, in that it all just starts up again, and runs from the last checkpoint.

The only way you could be running the SAME model again from so far back is from a restored backup. In which case, make the backups more frequently.
But it\'s more likely that you\'ve started a new model.

Data is uploaded once a model year, with larger uploads every ten years, and a restart dump every 40 years. So all of this will have been stored on the Oxford servers.
