The backups are extremely important because anything can happen. For example, a simple storm can burn the hard drive of your computer. In case you do not be a copy, you risk you have to throw away all that information, without the possibility to recover it. In case they are multimedia materials such as movies or music, you can always re-download. The problem is much bigger when it comes to personal data, photographs or simple documents which can not extract a copy.

They are installed, are configured (process that sometimes is minimal) and finally are implemented either manually or automatically. PC can recommend Cobian Backup. For Android exists Titanium Backup. No matter their names, with a small facility you will be covered in future data loss problems.
Backing up is extremely important, do not forget it. You risk losing data that you have stored on your device. A moment that could give a lot of headaches.
