The new OS from Mac is here in OS X El Capitan. Time Machine makes it simple, and other backup methods are also available.

Before installing any upgrade, it’s a good idea to back up your Mac. If your Mac isn't compatible with OS X El Capitan, the installer will let you know. Being the successor of OS X Yosemite, it mainly focuses on stability, performance, and security.There is a history in its name. Mac OS X El Capitan: Being the 12th major release of macOS, Mac OS X El Capitan belongs to the Macintosh-Unix family of OS.It was majorly released for server OS for Macintosh computers and Apple Inc.’s desktop.

In theory, you should have to install El Capitan only once, or never if your Mac came with El Capitan preinstalled. The process in El Capitan is (compared with root-canal work, income taxes, or previous versions of OS X) relatively painless.
