How the way we back up data continues to evolve

Backing up your PC and other devices has been a practice since the middle of the 20th century with the advent of magnetic tape storage, though one could argue it all started with punch cards. These tapes were colossal storage devices compared to USB and M.2 SSD drives of today and stored very little, with a capacity of just a couple of megabytes. This was a marvel at the time, but you couldn't even fit a three-minute .mp3 music track on one. We've passed through the ages with hard drives, floppy disks, solid-state storage, and the cloud.
