對于linux的應用，對它有很多研究的人都會知道它的命令是很關鍵的。linux定時調(diào)度使用crontab命令操作就可以實現(xiàn)，但要把遠程ftp目錄文件拷貝到另外一臺 ftp目錄里面。有人建議A機控制B機去抓C機的ftp數(shù)據(jù)，但這樣過于復雜，我們就需要一個sh腳步，就可以實現(xiàn)。

#file autobackup shell

# the end of the auto backup script
把以上shell腳本保存成文件，并配成可執(zhí)行的，配到crontab中即可實現(xiàn)自動備份。
寫在最后：對于這個shell腳本自己不是科班出生可能還是很難寫的，所以，在這里算是資源共享吧。
