I am running a rstan Bayesian predictive model in R which takes about 60 hours to determine the results. I'm currently doing this on my local desktop so I just keep it running till it's done, but we plan to put it on a server which may be affected by unpredictible downtimes. Is there any way to, say, partially save the binaries so that the program resumes from where it left off before the server went down? 

I'm not sure if this question follows all the rules of SO or if it has been answered before-in either case it would be great if you could point to an alternative resource before flagging it :)

Thanks
