Synchronization without change source

Hi there, Comodo Backup is great software, I’ve started using it 3 days ago and I can’t figure out how to configure this option:


What do I mean? I want to not change source, only change destination. If I delete file in source, this file will disappear in destination, if I change file in source this file will replace file in destination… Now I have two-way synchronization. When I delete file in source, but in destination this file exists CB will add this file to source - I don’t want to do that.

Do you have some advices for my problem?

Thanks a lot.
