We all know the great app created by Apple, that is Time Machine. It is a brilliant application that every user should have and use it. In case you can’t manage to use Time Machine as your backup tool, you might want to try an alternative way to take one time backup. Here is another way of taking backup of your Mac using Disk Utilities. We will use this tool to take image of your current volume which has OS in it and can be used for back up. This backup is better if you don’t have a dedicated hard drive but use it once a week or so. As soon as you get this drive, you take a backup and then can replace where you got it from. Taking backup of your machine is way enabled you to use the newly taken image as OS whenever your machine crashes or you get another machine and you want all the files to be as it is on your older one. Great feature, lets try and explore more.
