As far as I know, 80% of the system administrators are not too concerned about the security of their servers, but they tend to be quite interested in the technology of standby mirroring, but because commercial products are expensive in hardware and software, they tend to choose free software. This is the kind of software that is being introduced here to meet the most demanding backup requirements that are not particularly high. I. Introduction to the Characteristics

Background Our company is using Inotify+rsync to do real-time synchronization to solve the problem of distributed cluster file consistency. But when the Web files more and more (millions number of small files, such as html,jpg), synchronization is more and more slow, simply do not real-time, according to the online tuning methods have tried, the problem is not resolved. After my careful research, and finally the slow core of the study to understand,
