Mirror operated didn't work.

I'm using FFS on Ubuntu 22.04. I have it set to mirror sync from my main internal drive to my external USB connected hard drives.

I deleted a bunch of files on my internal drive and then did a Mirror sync to the external drive.

FFS then did something weird. It restored all the deleted files from the external drive back to the internal drive. This is the opposite of what FFS should have done. FFS should have deleted all the files from the external drive.

Why did FFS make this mistake? How do I get it to Mirror correctly?

Sounds more like a two-way sync without using a database, but I don't even think that is possible...
Are you sure you have the left side 'source' and right side 'destination' set correctly?

I got it resolved. Yesterday I wiped out Ubuntu and installed OpenSuse Tumbleweed. So I'm now using FFS to copy my files from my backup drives to my (mostly empty) internal drive. It's working good. I made a donation and installed the Donation Version of FFS onto OST.
