When game is saved in singleplayer, copy previous save instead of overriting it

[riess]

I've just been hit with a bug that caused my precious avorion flagship filled with top notch guns and systems to explode before my eyes as I've jumped to system it was waiting for me with my other ship. This was soulcrushing, but admittedly this is early access game so I've was kind of expecting to be bitten eventually.

 

Still, I think such a bug shouldn't be a slap into face and game should provide player with way out of such scenario in a form of previous save that may send one back hour or few in game progress, but save from greater frustration of losing days or weeks of gametime.

 

This is why I think game could copy the save instead of overwriting it when player quits. Eg. if I'm playing on "mygalaxy" and I'm closing the game, game would copy current galaxy to "mygalaxy-previous", and then create new "mygalaxy" file with current progress.
