有什么方法可以将数据直接从Dropbox服务器复制到UNIX服务器，而无需root或安装在此处的Dropbox软件？
类似：
rsync -aP myusername@dropbox.com:somepath/ .
（想要这样做的原因是，由于它们都在主链上，因此Unix服务器和Dropbox服务器之间的传输速度要比我的本地计算机和UNIX服务器之间的传输速度要快得多，后宽带连接）。
您可以使用WGET从命令行下载到服务器的文件。
之类的东西wget http://dl.dropbox.com/u/12345678/largefile.zip
如果您处于缓慢的链接，并且下载在下载所有文件之前就可以切断，则可以通过将-c选项与WGET一起使用。只是做：
wget -c http://dl.dropbox.com/u/12345678/largefile.zip
尝试rclone https://github.com/dropbox/dbxcli/issues/60#issuecomment-497713363

我不相信您对Dropbox服务器有访问权限。想一想，这意味着Dropbox服务器将拥有数千个SSH帐户，只是用户使用它的机会。此外，默认的UNIX用户可以访问读取大量的UNIX OS并将其限制在几个命令中，这很重要。想象一下，如果您的UNIX用户能够以某种方式看到其他Unix用户（包括其Dropbox数据）的数据。好主意。
