I once overwrote my own partition table. The next week was spend keeping the laptop on or in standby and investigating recovery. I never found a good solution so I started investigating alternatives, and ended with the so called nuke-and-pave, I Reinstalled Ubuntu. Anyway, that's quite a situation you have got there :) can you not suspend to disc and keep the suspend image safe and able to be booted into after power failures or so? Maybe suspend to disc (hibernate) and then image the swap partition/file? Then some grub editing... or... what OS is this anyway?
