我想安装 rsync 来每天备份我客户的服务器帐户，该帐户最近已迁移到 mycloud.rackspace.com。Rackspace 确实有一个教程，暗示它可以以通常的方式安装：
http://www.rackspace.com/knowledge_center/article/backing-up-your-files-with-rsync
我的问题似乎是它是一个旧的 Linux 版本。uname -a 显示：
Linux xxxx 2.6.16.29-xen #1 SMP Sun Sep 30 04:00:13 UTC 2007 x86_64 GNU/Linux
我尝试将反向移植添加到 apt 源列表中：
# cat /etc/apt/sources.list
deb http://ftp.debian.org/debian/ etch main
deb-src http://ftp.debian.org/debian/ etch main
deb http://security.debian.org/ etch/updates main contrib
deb-src http://security.debian.org/ etch/updates main contrib
deb http://backports.debian.org/debian-backports squeeze-backports main contrib
但是，我得到了同样的“未找到”错误，似乎没有尝试获取反向移植。“aptitude update”没有帮助：
# aptitude -t squeeze-backports install rsync

有什么建议吗？谢谢！
答案1
Debian Etch 的 EOL 和 EOS 已经很长了，网上没有它的存储库，这就是您收到 404 错误的原因。
