Imagine some mail server that works and extensively using some files.
I want to rsync files over ssh(mails and inboxes, all mail data) without stopping CommuniGate 
Is it safe?

Can I run rsync over currently running mail server?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
