rsyncはファイルを移動してディレクトリを保持しますか？

特別なオプションがありますrsync：

   --remove-source-files
          This tells rsync to remove  from  the  sending  side  the  files
          (meaning  non-directories)  that  are a part of the transfer and
          have been successfully duplicated on the receiving side.

          Note that you should only use this option on source  files  that
          are quiescent.  If you are using this to move files that show up
          in a particular directory over to another host, make  sure  that
          the  finished  files  get renamed into the source directory, not
          directly written into it, so that rsync can’t possibly  transfer
          a  file that is not yet fully written.  If you can’t first write
          the files into a different directory, you should  use  a  naming
          idiom  that lets rsync avoid transferring files that are not yet
          finished (e.g. name the  file  "foo.new"  when  it  is  written,
          rename  it  to  "foo"  when  it is done, and then use the option
          --exclude='*.new' for the rsync transfer).

          Starting with 3.1.0, rsync will  skip  the  sender-side  removal
          (and  output an error) if the file’s size or modify time has not
          stayed unchanged.

ターゲットファイルの削除は選択内容によって異なります。ただし、公平に言えば、などのオプション--deleteを使用しないと--delete-before何も削除されません。
