Yes, jump drives are very good. I have spent 6 of the past 30 hours rebuilding the parts of my game that were completely erased. This included the Scripts, about 10 maps, Mapinfos, Common Events, Tilesets, The game file, and System. I did this by painstakingly recreating them through hardcoding (witch copy+paste) or tricking RPG Maker into doing it for me. I'm pretty sure that this is what Blizzard was talking about doing, but anyways, im back in the game, so to speak, after my recovery.
So anyways, although flash drives are good places to store things, they CAN get lost easily. I am now storing my backup in a seperate folder on my computer, as an unencrypted game installer. Now, I guess i'll go to sleep.
