To understand how rapidly the global datasphere – the amount of data around the world that is created, captured, and replicated online – is growing, consider one word: zettabyte.

Put another way, eight years ago The Guardian described the amount of data contained in one zettabyte as being equal to 250 billion DVDs. Alternatively, Cisco's Taru Khurana says that if each gigabyte in a zettabyte were a brick, one zettabyte could build 258 Great Walls of China.

And now, new research shows that the total amount of online data created, replicated and stored will increase from 33 zettabytes in 2018 to 175 zettabytes by 2025.
