Data loss

When data loss, the temporary or permanent loss of data is called. When lost all the data that are not, as announced, on a data storage are effective.

Causes

A temporary loss of data occurs, for example if it can not be accessed by computer technical defects or if logical error in a superordinate level of the software or hardware hierarchy lead to a temporary non-availability.

However, data loss can also occur due to an unplanned situation in the routine operation of a computer, due to incorrect operation of a computer system, faulty software, misconfiguration or hardware defects. In addition, external factors such as theft, overvoltage, fluids, fire, or any misuse of the system can lead to data loss.

Also operating errors can lead to data loss. This refers to, inter alia, accidental erasure or overwriting of files, formatting disks, the mechanical damage of data carriers, but also to switch off a computer without the system shutting down cleanly.

Typical indirect causes for the occurrence of data loss are the activation of malware, file system errors or attacks by crackers. This requires rather a previous incorrect operation or improper software or configuration, which can then cause a loss of data. Indirect causes such as a recent computer virus are also common reasons for data loss, but not per se imply a loss-making system; but these causes can be prevented through preventative an optimally configured system.

Countermeasures

The risk for the occurrence of data loss can be through the use of a backup concept minimized, but not eliminated, per se, since the backup system can be affected by a loss of data. In many cases, you can recover lost data by data recovery. The chances of a successful recovery are directly dependent on which base is responsible for the data loss.
