我只能通过 ssh 通过最小救援系统访问我的虚拟服务器。它没有scp或ftp安装。有没有一种简单的方法来备份文件，最好直接备份到 ftp 服务器，但备份到我的本地计算机也可以。
也许这有助于展示救援系统的能力：

.ssh

答案1
tar cvzf - file1 file2 dir1 dir2 | ssh user@remotesystem "cat > /big/partition/rescue.tgz"
将是我的偏好。您甚至可以即时解压：
tar cvzf - file1 file2 dir1 dir2 | ssh user@remotesystem "cd /big/partition; tar xvzfp -"
但正如富埃罗指出的那样，人们也可以
rsync -avz -e "ssh user@remotesystem" dir1 dir2 remotesystem:/big/
（我的 rsync-fu 不是很好，所以上面的内容可能并不完美）。但你明白了；ssh可以用作任意数量事物的承载传输。
