All storage devices are at risk of malfunction due to various causes such as virus attack or human error. It is important to note that some data storage devices are overworked more than other. Such are prone to fail more than others.
Consider servers. Server Databases serve millions of users through the data they store at individual levels and the corruption in the weirdest scenario which eats up all the advantages they provide. The amount of pressure on their storage devices is so much that it would be easier to fall prey of malfunction faster than the client hard disk.
Another scenario to consider is a laptop. These machines allow individuals to carry out their daily tasks even when they are not at home or in the office. Most companies nowadays allow their employees to telecommute or bring their work at home. However, because laptops are mobile, the danger of data loss is higher compared to the desktop pc.
Backing up your files once a week is recommended. Back up your files using CD-RW or DVD-RW or you can backup your files online.
We can also take a case study of a flash drive. (Flash memory). It gets its name due to its microchip arrangement in such a way, that its section of memory cells gets erased in a single action or "Flash".
Since flash memory is portable and data can be deleted from them, they are such mobile storage devices hence prone to threats such as theft, viruses or Trojans that may malfunction it.
but even if the worst happens you don't have to worry about data loss because data recovery is possible.
