7zip 在windows command line的指令方式

因為工作上自動備份的需要,所以就查了一下指令
目前windows 10 取日期還有問題,我還在想要怎麼處理

極致壓縮
7z a -mx9 filename.7z files/Directory

極致壓縮 加密碼
7z a -mx9 -pPassword filename.7z files/Directory

極致壓縮 8匹馬(threads)沒有密碼,指定為7zip格式
7z a -mx9 -mmt8 -t7Z filename.7z files/Directory

一樣有圖有真像

原來的檔案大小是23G, 7zip壓縮完的檔案,只有741MB,用了40分鐘左右壓完
測試解壓縮沒有錯誤
好可怕的壓縮率
