My PC is indeed a laptop. Would it be possible to use a Raspberry Pi (or other device) to store data from the console's datalogger?
More simply, just leave your laptop running. It will do fine, and has it's own "UPS" (internal battery) in case the power goes out for a few hours. I'm assuming your VP2 console has good batteries for backup and is normally using the AC supply.
If you are really really really worried - change the archive interval to something that will last for 9+ weeks, even if everything else dies.
Oh, but what if the ISS dies.........
