Data Loss - Types of Data Loss

Types of Data Loss

  • Intentional Action
    • Intentional deletion of a file or program
  • Unintentional Action
    • Accidental deletion of a file or program
    • Misplacement of CDs or Memory sticks
    • Administration errors
    • Inability to read unknown file format
  • Failure
    • Power failure, resulting in data in volatile memory not being saved to permanent memory.
    • Hardware failure, such as a head crash in a hard disk.
    • A software crash or freeze, resulting in data not being saved.
    • Software bugs or poor usability, such as not confirming a file delete command.
    • Business failure (vendor bankruptcy), where data is stored with a software vendor using Software-as-a-service and SaaS data escrow has not been provisioned.
    • Data corruption, such as file system corruption or database corruption.
  • Disaster
    • Natural disaster, earthquake, flood, tornado, etc.
    • Fire
  • Crime
    • Theft, hacking, sabotage, etc.
    • A malicious act, such as a worm, virus, hacker or theft of physical media.

Studies have consistently shown hardware failure and human error to be two most common causes of data loss, accounting for roughly three quarters of all incidents. A commonly overlooked cause is a natural disaster. Although the probability is small, the only way to recover from data loss due to a natural disaster is to store backup data in a physically separate location.

Famous quotes containing the words types of, types, data and/or loss:

    Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.
    Talcott Parsons (1902–1979)

    ... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.
    Albert Camus (1913–1960)

    This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.
    Susan Sontag (b. 1933)

    The poorest children in a community now find the beneficent kindergarten open to them from the age of two-and-a-half to six years. Too young heretofore to be eligible to any public school, they have acquired in their babyhood the vicious tendencies of their own depraved neighborhoods; and to their environment at that tender age had been due the loss of decency and self-respect that no after example of education has been able to restore to them.
    Virginia Thrall Smith (1836–1903)
