我使用（Aegir3，Drush 7.1.0，provision 7.x-3.4，hostmaster 7.x-3.4）在 Debian 服务器 Jessie 上手动安装了 Aegir 包，一切都很顺利，除了备份功能，这是我所做的：
我激活了 Hosting Site Backup Manager 模块来自动备份我的网站。
*********我无法在 /var/aegir 中安装 aegir（因为我对该服务器上的其他目录没有权限），但它安装了 /production/my_aegir_user 具有所有 aegir 权限用户* ********
使用 Aegir 安装新站点后，当备份任务运行时，它会失败并显示以下日志：
