提前备份服务器home目录

 我把整个目录（其实就俩压缩好的tar.gz文件)重新压成tar.gz
 本来想电脑下载，结果发现......服务器上传带宽太低了600MB的文件阿里学生机1Mbps得下载到多久啊，于是SSH连上我家云。

apt install wget
...........(armbian里没有自带wget，倒是编辑器nano和vim都很齐全。）
wget -b https://xfox.fun/backup/homebackup.tar.gz
//文件很大一时半会下载不完所以用-b 参数
Continuing in background, pid 12804.
Output will be written to ‘wget-log’.
//查看后台文件下载状态
root@Chainedbox:/home# tail -f wget-log
