We rely so heavily on the content stored on our computers, smartphones, and tablets; it is shocking to think of how many of us do not back up our data. Backup data is essentially creating a mirrored version of the content within your device and storing it elsewhere for safekeeping. Creating a copy of a document and storing it on the same device is not the same as backing up. A copy of your data should be transferred outside of its current device, not copied and stored locally. By saving your documents outside of the original device, you ensure that in the event of theft or damage, your documents are still accessible.
We are fortunate enough to have access to many options when it comes to backing up our devices. In the early 2000s and late 1990s, zip drives were the easiest and most popular way to back up data. Each time we wanted to create a backup of the data on our computer, we would insert a USB device and save everything to this device. The files on our machine were compressed and stored for safekeeping.
