Most of the devices we use today can capably perform a number of functions. This, of course, was not always the case. Cell phones were just that….phones. Even placing calls on them was often challenging and sending a text was more of an annoyance than traveling to see the individual and delivering the message in person. There was no such thing as a USB flash drive or portable HDD. Backups were often done on tape for extreme reliability (unless, of course said tape happened to get to close to a magnet), but was slower than the aforementioned dial up modem, or the acclaimed Zip Disk which could back up a whopping 100MB in a blazing time of around five minutes. Thankfully, that has changed. It has become quite common to see USB 3.0 portable HDD with speeds that rival installed disks, are reliable and can offer data encryption for greater security.
