If you routinely capture the activity of the streets or get-togethers with family and closest friends by using your Android smartphone, it helps you now add one more to perpetuate the agenda of those moments: backup data stored on a smartphone or SD card to computer.
As with any other electronic device, internal memory or SD card is not a component that will endure eternal of all sorts of situations. If the HDD in the computer can be damaged even if used with extreme caution, it is also very likely to occur on the SD card in your smartphone. There have been many reports are emerging that the SD card is suddenly dead / not accessible and all data on it is lost, and the application of any recovery will be difficult to bring it back.
The same thing also applies to the internal memory in the phone. Even if the data is corrupt cases fairly rare, but activities such as 'do not accidentally delete data' has become a common problem. Especially if you are a user who likes fiddling with smartphones and flashing the ROM, then the agenda backup data to a computer is one thing that is absolutely necessary.
No matter how big / small capacity of the SD card / internal memory you use, you should never rely on it to store your valuable data. Backup the data on one computer only sometimes also still at risk, then do not forget to back them up on your laptop or collect these data in a file, then burn it to a CD / DVD blank. Therefore, beware!
