1.1.3 Performing backups
1.1.3 执行备份
Performing backups is perhaps the most important job of the system administrator, and it is also the job that is most often ignored or sloppily done. Backups are time consuming and boring, but they are absolutely necessary. Backups can be automated and delegated to an underling, but it is still the system administrator’s job to make sure that backups are executed correctly and on schedule (and that the resulting media can actually be used to restore files).
执行备份可能是系统管理员最重要的工作了这也是经常被忽视或者不经心去做的工作。备份工作耗时且单调但又绝对必要。备份可以自动进行且能授权给下属去做但系统管理员仍然要确保备份工作在按时正解进行备份介质确实可以恢复出原文件来。

1.1.4 Installing and upgrading software
1.1.4 安装和软件更新
When new software is acquired, it must be installed and tested, often under several operating systems and on several types of hardware. Once the software is working correctly, users must be informed of its availability and location. As patches and security updates are released, they must be incorporated smoothly into the local environment.
在获得新软件以后必须安装并测试它而且经常要在几种类型的操作系统和硬件下进行安装和测试。一旦软件能够正常工作还要告诉用户这个软件的位置。在补丁和安全升级发布出来的同时也必须平稳地将它融入到本地环境里。
Local software and administrative scripts should be properly packaged and managed in a fashion that’s compatible with the native upgrade procedures used on systems at your site. As this software evolves, new releases should be staged for testing before being deployed to the entire site.
应该把本地软件和管理脚本正确地打包和管理使之适用于本地系统自身采取的升级机制。随着该软件向前发展新的发布版本应该先安排测试然后再部署到整个站点上去。

1.1.5 Monitoring the system
1.1.5 监视系统
Large installations require vigilant supervision. Don’t expect users to report problems to you unless the issues are severe. Working around a problem is usually faster than taking the time to document and report it, so users often follow the path of least resistance.
大型的部署环境需要时刻进行监视。除非事态严重否则不要指望用户向系统管理员报告问题。比起花时间写说明报告问题绕过问题通常要快得多所以用户往往怎么省事怎么来。
Regularly ensure that email and web services are working correctly, watch log files for early signs of trouble, make sure that local networks are properly connected, and keep an eye on the availability of system resources such as disk space. All of these chores are excellent opportunities for automation, and a variety of off-theshelf monitoring systems can help sysadmins with this task.
