3. Software Corruption

Almost all of us have experienced that the software we are using shuts down suddenly without reasons  when we are making an important document or editing a picture. Such scenarios are called Software Corruption, which is cause by using some diagnostic tools or taking too much memory, etc.

Prevent Measures:

- Have a good working habit – save your documents frequently during the process of editing.

- Use diagnostic utilities with caution.

Contrary to the causes of data loss listed above, natural disasters are the most uncontrollable cause. Such as, fires, floods, earthquakes, even brownouts, all of them are out of our control. Fortunately, according to the survey, only 3 percent of users lost data because of natural disasters.

Therefore, it is more important for you to minimize the risk of data loss caused by the reasons listed above, especially the human errors. But we still provide you several tips to avoid the data loss as a result of natural disasters bellow:

- Store important but not sensitive data with cloud storage service, such as, Google drive, iCloud, etc.

- Install a UPS.
