Backup chain confusion

[studiorion]

I've been searching for software like this for a while, and FreeFileSync has been working exactly how I need it to, so I'm very thankful it exists! I'm having some confusion that I'm hoping someone smarter than me can help me out with.

I have a working folder (sessions) that I backup to multiple places and I manually delete non-active projects from the main folder to save space on my main drive. I have setup individual files in FFS that work perfectly. They compare the source folder with the backup folder and copy only new/edited files. I love it.

Now, I'm trying to batch and schedule these tasks to run every night while I'm not at work. I have:

task1: Backup from "sessions source folder" to f:\Sessions
task2: Backup from f:\sessions to g:\sessions

I followed the tutorial on the site for setting the scheduler and it ran at the prescribed time, but I was hit with an error that I'm not sure how to get around for what I'm looking to do. It said there was an error because of multiple folders being the same and that I needed to create an exclusion. Since I only understand a small part of what it's saying and knowing my luck and general intelligence level, I'm going to end up deleting everything if I try to solve it.

Can anyone help me do this properly so I don't mess everything up?

Thanks!

This is because you are running an A->B sync and then a B->C sync.
Change your FFS configuration to sync the source folder directly to f AND g

Beautiful, I will give that a go, thank you!
