Internet hive mind.
My dad's old Synology NAS is nearly full, mainly it is used to backup his desktop on which he edits his photos. The backup is just rsync so syncs one way, but doesn't remove duplicates when he moves things round.
I'm looking for a tool I can point at a mounted volume that will find duplicates and near duplicates (e.g. cropped versions) of photos and create an index.
Anybody know of a OpenSource tool that does this? Don't want to have to install Immich
