Too much overlap between brokerage and backdoor Roth? VOO and VTI strategy

Hello im still relatively new to investing but want to be more consistent this year with my money for my future. Is there too much overlap with the following strategy? Is it redundant to have both VOO and VTI in different accounts? Brokerage: 70% VOO 20% VXUS 10% SCHG Backdoor Roth: 65% VTI 25% QQQM 10% AVUV I figure my brokerage holds long term growth potential + international exposure while my Roth focuses on additional diversification. Please let me know your thoughts, I’ve been lurking for over a year and saving a lot of your guys posts/comments for my own reference/learning lol so open to further recommendations and thoughts !
