A new trend has been to back up files online. The cost is usually determined per gigabyte. For example, 5GB of storage space costs up to $30 / month. The more gigs you have, the cheaper the overall price is. However, the price is is still 
expensive due to how your files are backed up. Online backups are basically someone with a computer like you who backs up your files onto a hard drive. The only difference is that they are hosting your files from a web host.
The good news is that you can back up your files online on your own! This can save you time and money.
Here’s how to do it:
1. Sign up for a domain if you don’t already have one. A domain is your own website address.
2. Host your own website.
Steps 1 and 2 may be done by subscribing to a web host, such as GoDaddy
3. Within your host, set up a username and password for your FTP account. An FTP account allows you to save your computer’s files to your server.
4. Transfer files from your computer to your ftp account. You may do this by going to a web browser and type in: ftp://www.yourdomain.com & enter your username and password. Then copy and paste files into the white box which is your web space.
Although setting up a web host with a domain is typically for creating your own website, you may use this method as a smart way to save important files online. Backing up this way can be as cheap at $5 / month for 100GB!. Usual online backups costs at a minimum of $400 / month for such storage.
Here’s to smart computing!
