The issue of the backup/sync function not working correctly on Windows 10 is addressed in several posts.
I have been having this issue for at least 3 years on multiple computers. I am occasionally able to get it to work. Going thru the Support system multiple times has been fruitless and frustrating. This is an issue that is not a priority for Webroot. It was suggested to me that I use Carbonite. Why are they advertising the backup/sync on the sales page when it doesn’t consistently work? They need to fix this issue or remove backup/sync from the product. This used to be a great feature that was a major part of my decision to use Webroot. I am now considering a different product. I have been a loyal Webroot user for several years and kept hoping they would fix the issue. I get it that their main product is security. But their lack of dealing with a persistent problem in a part of the product package causes me to question the integrity of the whole product.
