You can create an off chain merkle tree with an unbounded number of transactions in it and store just the header on-chain. This makes all the data in that tree immutable. Store a live feed of your life. 32TB/year at 1MB/second or around $450 at $0.015/GB

Ahh I see.. should be many applications for data integrity.
