然后去看看文件：
<code>[root@crifan wwwroot]# ll -lha total 5.4G drwxr-xr-x 6 root root 4.0K Mar 20 16:00 . drwxr-xr-x. 5 root root 4.0K Sep 5 2017 .. drwxr-xr-x 5 www www 4.0K Dec 6 16:19 book.crifan.com drwxr-xr-x 3 www www 4.0K Sep 10 2017 crifan drwx--S--- 12 www ftp 4.0K Mar 20 16:00 p7zip_16.02 -rw-r--r-- 1 root root 4.1M Jul 14 2016 p7zip_16.02_src_all.tar.bz2 drwxr-xr-x 13 www www 4.0K Mar 20 11:10 www.crifan.com -rw-r--r-- 1 root ftp 5.4G Mar 20 12:00 www.crifan.com_allFiles_20180320.7z </code>
5.4G
去用ftp下载下来：
苏州移动
下载速度很不错：2MB/s
【总结】
用7z去压缩：
<code>7za a -t7z -r -bt output_filename.7z folder_to_compress/* 7za a -t7z -r -bt output_filename.7z file_to_compress </code>
比如：
<code>7za a -t7z -r -bt www.crifan.com_allFiles_20180320.7z /home/wwwroot/www.crifan.com/* </code>
