I have heard of people losing data from their computers systems. Dear Security Conscious tIt is true that data can be lost from computer systems. Systems can go down.
Hard disks can crash.
Viruses may destroy data. All these problems can be avoided, however, with proper data management techniques. By implementing a system that has built in redundancy, checks for integrity of discs and data, and has automated back up procedures, you can be confident that your data is secure. The most common cause of irretrievable data loss is user error. Users have to learn to routinely save their data as they go and to save all work on exiting.
