It is really frustrated when your Mac computer goes to dead and you realise that you haven't backed up. Especially when you have used the computer for a long time and have many previous data saved there. You may lost a whole bunch of stuff that's irreplaceable - Photos, music, videos, documents. All Gone.
So, to avoid such a kind of dilemma. Let's face it. Backup your Mac hard drive regularly.
In Google's study, nearly 3% of drives failed in less than three months. And if your drive is one of that 3%, without a backup you will have lost your precious data.
For Mac users, to prevent files and folders from losing, you should back up your Mac data with Mac backup software, such as Mac OS X built-in backup software Time Machine. If Time Machine is not available, you can backup Mac hard drive with other Mac data backup software.
Time machine can backup all items including system files, application, music, photos, movies, documents and so on. It is available for Mac OS X 10.5 Leopard, 10.6 Snow Leopard, 10.7 Lion and 10.8 Mountain Lion, 10.9 Mavericks and the latest 10.10 Yosemite. Also it is better than other Mac backup software for it not only keeps a spare copy of every file, but also have a snapshot of the system for the past 24 hours one day, daily backups for the past month, etc. View my previous post - Backup Mac with Time Machine in details. Here is a short tutorial.

The answer is definitely yes. There are many alternative tools available. A chart from Top Ten Reviews shows the best and most popular Mac data backup software in 2013.
