我有一个备份服务器，可以备份其他服务器，几天后，备份服务器开始遇到错误并且无法恢复。我认为下面的错误日志比我更能描述问题：

笔记：我正在使用 backuppc 进行备份。备份服务器能够为其他服务器进行备份，但其中一台服务器出现错误。所以我相信在那个特定的方面一定存在一些问题客户服务器使其过早退出。
更新：
网络接缝要OK（网络统计输入）在客户端。

在上面的输出中，我看到它显示超时，但我在配置中增加了超时变量。
答案1
只是在黑暗中拍摄，但是在这个问题开始出现时，客户端备份目录中的文件数量是否显着增加？消息
（由信号中止=PIPE）
让我想起了 Unix 管道。在备份命名法中，该管道可能是文件名管道。当文件数量超过一定的缓冲区大小时（在不了解服务器和客户端的系统架构的情况下无法详细说明），您可能会遇到此类错误。由于此错误来自我不熟悉的备份应用程序，因此我无法证明该消息与文件数量之间的相关性，但检查一下并没有什么坏处。
如果是这种情况，您如何解决它完全取决于您。通过消除较旧的文件或创建子目录并将一定数量的文件推送到这些目录中来修剪目录。或者两者的结合。
祝你好运
