Any way to sync directory structure when the files are already on both sides?
I'm looking for a backup utility that recognizes files or folders in the source that have just been renamed or moved. Using rsync I get a lot of duplicates, when ideally it would reflect those operations on the target (like Microsoft's SyncToy does).
Example:
Source: Target:
~/done/a ~/done/a
~/done/b ~/todo/b
~/todo-123/c ~/todo/c
~/todo-123/d ~/todo/d
