WPVivid Backup error

I am trying to backup my WP site and database so that I can eventually move it from being hosted on my computer to hosted with my website hosting provider. When I run the WPVivid Backup plugin i get the following error message (sorry I couldn’t find a better way to add the image - click to enlarge):

Is there a way to fix this? It may not be necessary to backup anything up since it is on my computer. I am new to local hosting. Thanks.

I am also now receiving this EXACT same error.
