rsync : salin file jika file lokal tidak ada. Jangan periksa ukuran file, waktu, checksum, dll

apakah Anda mencoba tanda ini -- ini mungkin membantu, tetapi mungkin masih memerlukan waktu untuk melanjutkan transfer:

       --ignore-existing
          This tells rsync to skip updating files that already exist on the destination  (this  does  not  ignore
          existing directories, or nothing would get done).  See also --existing.

          This  option  is  a  transfer  rule,  not  an exclude, so it doesn't affect the data that goes into the
          file-lists, and thus it doesn't affect deletions.  It just limits the files that the receiver  requests
          to be transferred.

          This  option  can be useful for those doing backups using the --link-dest option when they need to con-
          tinue a backup run that got interrupted.  Since a --link-dest run is copied into a new directory  hier-
          archy  (when  it  is used properly), using --ignore existing will ensure that the already-handled files
          don't get tweaked (which avoids a change in permissions on the hard-linked files).  This does mean that
          this option is only looking at the existing files in the destination hierarchy itself.
