Overview: In Linux system administration, it is often critical to replicate data to another server for high availability. There are several possible methods, including simple asynchronous copies, developing change detection software, and using synchronous cluster file systems. These methods all have pros and cons. Equally important is the kind of data to be replicated. Large files, small files, and frequently changing files impose different requirements. These issues are discussed, and in conjunction with the different methods, an effective replication scheme can be chosen for any environment.
