Before you install Mountain Lion from the Mac App Store and begin the process of upgrading, make sure you back up your Mac.

Backup means “keeping another copy of data for future use”. Mac users can create backup by following methods:-

When you plug-in a Mac-formatted external drive to your Mac, it will ask you - if you want to use it as a backup with Time Machine. Time Machine creates incremental backups which is very useful to find deleted files.

By default, Time Machine save backups hourly but you can change it as per requirements on weekly or monthly. Rest space of Time Machine backup device can be used to save another data files. But, the problem is, Time machine can not make bootable backup or clone. And Time Machine doesn't enable you to back up over the internet , you can use it with local network.

2. Third Party tool – Stellar Drive Clone, Super Duper, CCC etc. are famous third party tool among Mac users. Bootable DVD can be made easily by using cloning tool of Stellar. It helps you to create either clone or image of Mac data. It is based on highly reliable techniques which ensures you for your data safty. You can create either clone of entire Mac or a particular volume. You can easily restore data in its original form using this clone.
