Data loss must be identified from information inaccessibility, which include may arise from a network outage. Even while the two have substantially similar consequences, information inaccessibility is temporary while information loss is permanent. Data loss is also discrete from information spill, even though the term “data loss” has been sometimes used in those incidents. Data loss incidents can, nevertheless, even be information spill incidents, in case media containing sensitive data is lost and subsequently acquired by another party. Nevertheless, information spills are possible without the information being lost in the originating side.

Several Types of data loss cases

Intentional Activity

  • Intentional removal of a data file or software program.
  • Unintentional Activity
  • Unintentional removal of a data file or software program.
  • Malfunctioning of CDs or Memory sticks.
  • Administration computer errors
  • Unfeasibility to read unidentified file format


  • Power outage, ensuing in information in volatile computer memory not being saved to permanent computer storage.
  • Computer hardware failure, which include a head crash in a hard disc drive.
  • A software system crash or freezing, resulting in information not being saved.
  • Software system glitches or poor usability, which includes not sustaining a data file Del command.
  • Business failure (seller bankruptcy), where information is stored using a computer software seller using Software-as-a-service and SaaS data escrow has not happened to be provisioned.
  • Data file corruption error, which include file system corruption or database error.


  • Natural calamity, earthquake, flood, hurricane, etc.
  • Flame.
  • Criminal offense
  • Stealing, hacking, sabotage, etc.
  • A malicious human activity, such as a worm, computer virus, hacker or fraud of physical media.

Surveys have consistently shown computer hardware failure and human fault to be two most typical factors that cause data loss, accounting for approximately three quarters of all incidents. A normally overlooked reason is a natural disaster. And even though the chance is small, the only way to retrieve from data loss arising from a natural disaster is to store backup data in a physically separate location.
