Yes, I also agree that the wiki needs perfection, but we don't really need another backup, as Shadow said, we just need to help Tendou with his backup or help him with his other to do list so he has more time for it.
Since they're going to be on the same site, and the site crashes, having a another backup on the same site won't help. If need be, if Tendou has all the images on his computer, he can upload them again on another site, in case something happens to the current backup.
Having two Image backups, what backup would someone use to replace a image? I just replace a image using the backup we have now, because I knew where it was, where to go and found the image, just one image. Having another backup, which one would we use? Would we say that one image looks better then the other? Would we be spamming the Recent Changes? Going from one backup to the other?
Since, right now, its mostly about the armor and the quality of the armor, and the armor background, I think it would be alright if the 2nd backup was just for armors and armors only. That way, someone else could manage the armor images. Less time messing with the downloading, the uploading and the organizing , and no fighting over which image from which backup is better. Tendou would have one less thing to worry about.
I'll help with what I can, either way we go.
