Freefilesync - Odd errors trying to mirror drives

TrueNAS General
1

On Ubuntu I have a EXT4 data drive I want to 100% mirror and keep in sync with my TrueNAS ZFS drive.

I have the NAS drive setup as a smb share on the Ubuntu machine, I copied over the data to the NAS. The Ubuntu and NAS will be creating files, so I want to sync both ways.

On the Ubuntu machine I am running FreeFileSync, and this is the error I get.

Cannot rename “/mnt/Media-DS/Home_Movies-DS/2012/20120101/P1010171-5a2f.ffs_tmp” to “P1010171.avi”.

The name “P1010171.avi” is already used by another item.

It sounds like the file already exists and that it’s refusing to rename over it to avoid losing the existing copy.

I was thinking the same thing… How do I change those settings so I can overwrite it?
