rsync で --partial を使うというのはどうでしょうか。

--partial
       By default, rsync will delete any partially transferred file  if
       the  transfer  is  interrupted. In some circumstances it is more
       desirable to keep partially transferred files. Using the  --par-
       tial  option  tells  rsync to keep the partial file which should
       make a subsequent transfer of the rest of the file much  faster.

失敗または中断した次の実行時に、続きをやってくれるらしいです。
