What is a Computer Backup?
The simplest definition of a computer backup is an exact copy. In the case of computer files, we are referring to copies of the original files that you have on your laptop, desktop, or external drive. Creating a backup of original content means having that data saved in two places, but it’s also important to make sure that those two places aren’t on the same type of device. For example, if you have 3 copies of a working document on your computer, if your computer crashes, you will still lose all three. This makes the backup method and medium, an important thing to consider for your backup strategy!
In most cases, a simple thumb drive (or flash drive) is the first way most people save their data. Thumb drives are easy to transport, work with most computers, and are relatively small. That makes them a great way to save small amounts of data like presentations or working documents. It’s also easy to give them to others, making them great for collaborative projects.
The downside to thumb drives is that they are usually very small and often are not very dense (meaning, they cannot store a lot of data). This makes them problematic for a few reasons. If your thumb drive is small it’s easy to lose. If you lose your thumb drive then you’re no longer backed up! Not having a lot of storage density is also problematic, as typically a thumb drive will not be able to hold all of the data that is on your computer. For all of those reasons thumb drives are not an ideal solution for backing up your computer.
