What is the recommended way of backing up files for BOINC tasks / projects? (on Linux Mint)

After running my first WU for just over 2 weeks and getting around a third of the way through the task, it has aborted with computation errors and the next task has now started. On the web-page for the project (climate-prediction) there was one line about making regular file back-ups but no advice on how and what to back-up. And I can't see any advice on this site either.

That was from a decade ago, when the number of models being run on a computer was just 1 or 2.
And it really only applies to Windows OS, in case of an unexpected auto upgrade.

With Linux, if a model crashes, then that's usually it.
You need to look at the Event log messages for that model to see what happened.

And these days, a computer only gets one chance to run a model.
If it fails, then it's sent to a different computer.

Ok, so once the failure message gets sent, there's nothing I can do to back track on that WU, correct?
So how often do tasks crash?

btw. can't look back at log now because I restarted my machine, hoping the task would restart from the last checkpoint. But the task isn't there anymore so I can't get the log back.

Anyway, thanks for you help and the speedy response

Les was referring the stderr of the task that can be seen at CPDN site under your Account -> Computers -> Tasks.

Ok thanks. Didn't know that was there. It just says 'Error while computing'.
As error messages go its not the most illuminating but I guess they thought any more detail than that was unnecessary.

Anyway, thanks for your help too.

unless there are any other comments I'm happy for this thread to end here.
Thanks
Take care

If at that point you click on the task number it will bring up more details including the stderr contents.
