What is data loss?

Data loss, sometimes called Data Loss event, is the term of information technology that refers to permanently lost data of computer data due to unexpected circumstances. Among the common causes of data loss are power failure, intentional or unintentionally erase computer files or programs, various hardware and software problems, a harmful computer virus or computer hacking. There are different types of data loss, such as shortening data, which makes the user data unavailable because they are not properly stored; damaged data that puts errors into data to be inaccessible or ineffective; and complete loss of data that can occur if the files are deleted. In many cases, data can be restored to obtain access to lost data, but this is not always possible. To avoid data loss, it is recommended that users make regular and frequent data backup using multiple partitions on the hard disk and also install power protectors and battery backup systems.

eXistanti than the loss of data that the user can lose access to data. For example, data unavailability occurs when data is inaccessible due to power outages, network problems or other temporary problems. Unlike data loss, this loss of access to data is not permanent. Data can also be stolen or otherwise obtained by an unauthorized party, sometimes called data leak or data leakage. However, data leakage does not always lead to data loss from the original computer.

data recovery is sometimes possible using specific procedures. For example, a hard disk recovery can be made with qualified computer techniques and corrupt partitions can often be restored. In some cases, you can accidentally delete the files to re -assemble and restore the data. One of the simplest ways to avoid data loss problems is to create a backup copy of computer files and programs that can be used to restore the lossCenter. This backup should be stored on a safe medium such as a separate hard disk or computer, CD or memory sticks.

In some cases, data loss is unilateral. For example, if the files are rewritten rather than simply deleted, the data is usually permanently lost. Therefore, it is not recommended to add new data to your computer if the data has been lost until the data recovery attempt is. Physical damage to the hard disk can also often prevent data recovery. Repeatedly restarting the computer, if the data loss has suffered due to problems with a physical hard disk, it may worsen the problems.
