~/media is RW to Sickrage. If it deletes that file from ~/media then unionfs will whiteout that file and copy the new one over. ~/media will look perfect. You just need to sync up whats been whiteout. I do this:
I had the same issue. I had local media copy up to Amazon nightly. Then, when a higher quality file downloaded, I’d end up with both copies. I solved this by adding a post-processing script to delete the lower quality version from Amazon. I use Sonarr, so there are some environment variables passed to the PP script that let me build the string needed to find and delete the old copy.
@calisro regarding the SYNC you mentioned, if I’ve been doing an RCLONE COPY for a while without running the SYNC command right after will it still work correctly and only remove the lower quality versions from ACD if I run it now for content that’s been replaced days ago
