File Sync & Backup Software | GoodSync. What would happen if all of your essential files disappeared? You can't see them. You just assume they will appear when you click an Icon or a file name on your computer. But, these digital files are invisible to the human eye, and all you see is a visual representation of them on a screen. Every document you have ever created for a client. Every financial transaction. Every personal photo. Of course, much of what we do these days is saved in the cloud, on a website proprietor's server; but, what would happen if you couldn't get online? What if a hurricane knocked out your computers and your access? What if. It's a big question. I have a file set that I call Essential Files. It includes every photo, document, poem, or other data that I have created over the past 30 years. In digital form it takes up over 30 Gigabytes of space. But, I sync and copy it to a USB Drive, and a Micro SD card alternatively, in about 15 minutes. Small price to pay for the security of my life. Have you backed up your files lately?
