Backing up data is actually easy. But when it comes to backup Wii games it becomes tough. This is large because the data on the game disks is copy protected. This means the data can not be copied in the normal way. Many people often give up on backing up this data simply because they do not know how to do it. But you can do it easily. All that is required for backing up the data is a software that will break the copy protection, an empty disc, a CD / DVD writer and a burning software. While the latter three are easy to obtain and most computers today have them installed already, the first one is the only thing that you would have to find out. There are a lot of softwares for this, which break the copy protection, and you can get them from many software sites.
Once you get the software, all you need to do is run the program with the game disc in the DVD-drive. The software creates an image of the entire data on the game disc, safely backing up your game and all other content on the disc. You can then use this image and the burning software to create a copy on another empty disc. This way you can easily take safe backups of the Wii games, because as we all know, the games cost a lot and if you lost them, it would be very bad. Many people are now doing this in order to save all their game data!
