利用tar點樣把日期變成檔案名?

打算每星期backup一次某個/幾個directory, 點樣可以利用tar 把當天日期變成檔案名?

例如 :
當天是 2012年3月1日

打算backup /var/www/html 及 /lib/mysql

輸出的檔案要係 = "backup20120301.tar.gz"

要響tar 加d乜option?

麻煩哂!

隔左起過年半更新下先, 可能有師兄會覺得有用
以今日(20/09/2013)進行backup為例, 想用以下格式儲成檔名有日期的tar.gz
最終檔名: file-20130920.tar.gz
指令如下:

tar zcvf "file-$(date +%Y%m%d).tar.gz" /directory_name
