rsync
está se comportando corretamente. Se você não quiser recriar o diretório de nível superior dentro do destino, deverá acrescentar uma barra ( /
) à origem na linha de comando.
De man rsync (1) :
A trailing slash on the source changes this behavior to avoid creating an additional directory level at the destination. You can think of a trailing / on a source as meaning "copy the contents of this directory" as opposed to "copy the directory by name", but in both cases the attributes of the containing directory are transferred to the containing directory on the destination.
