Like many other daemon, a daemon sub-process is fork for each connection. At startup, it will parse the rsyncd. conf file to determine which modules exist and set global options.When a defined module receives a connection, daemon will fork a sub-process to process the connection. Then the sub-process reads the rsyncd. conf file and sets the option of the requested module. This may cause chroot to the module pa

Brief introduction
For the choice of Linux as an application platform for small and medium-sized enterprises or Web sites, often face how to achieve remote Data backup or Web site mirror image of the problem, although there are commercial backup and mirror products to choose from, but these products are often too expensive prices. So how to use free software to efficiently implement remote backup and Web site mirror image is a topic worthy of discussion.
