Hi guys, wondering how rclone union mount handles conflicts/duplicate files?

My setup involves keeping most files locally and a cloud backup of everything. But I've deleted some files locally that still exist on the cloud.

At the moment I use a script to generate an exclude file of my local files and then mount my cloud remote with it. But I'm wondering whether I can use rclone mount to just only mount the missing files that are stored on the cloud. I assume this can also be done with mergerFS but the documentation seems overwhelming so I'm looking into rclone union first.

Using Debian Server and Google Drive for my cloud storage.

Thanks.

You should be able to do that, I would have though the `epall` policy is what you want.

I wish there were more examples for creating useful unions...
