Nioh data got corrupted?! And my last online save was from July, is there anything I can do to fix this?

I can't believe this had to happen now, the power died while it was saving at my house, And the file got corrupted, and the only backup I have is from July. I tried to do a rebuild database as well hoping it would recover it from an earlier time but no luck.

Is there nothing else I can do? Do I really have to go through all that again?
