What is Data Recovery All About?

What to do if an individual or an organization loses their vital data? The lost data is not an umbrella or a cane, for which an advertisement can be placed in the lost property columns of a local newspaper. It requires much more than this. Data loss is an undeniable and unavoidable reality in today’s tech world.

First of all, the thing to keep in mind is that, despite all the technological advances, all the storage media that are popular today tend to have a definite shelf life. For example, hard drives have a useful life of three to six years. Optical discs have a half-life of about thirty years. Hence, data loss can occur due to storage media failure. Other common reasons for data loss are hardware or system malfunction, virus or malware attacks, human error,data recovery software corruption or program malfunction, and natural calamities. As it is possible to lose data, we need data recovery.

What is Data Recovery?

Data recovery is the process of recovering data from a damaged or corrupted storage medium, when it is impossible to access it using the usual procedures. Data recovery also involves recovering deleted files from storage media. Data recovery services are usually provided by highly specialized companies, who have the experience and knowledge to perform this complicated task. Highly trained data recovery technicians use a variety of software and hardware tools at your disposal to recover lost data.

Why do we Need Data Recovery?

Due to the widespread digitization of institutions and organizations in recent decades, the rate of data generation per year is constantly increasing. Businesses and corporations have fully computerized almost every aspect of their daily activities. In such a situation, where businesses rely heavily on saved data, a potential data loss disaster can jeopardize the very survival of a concern. Physical assets are increasingly being replaced by virtual assets and every bit of data is sometimes worth its weight in gold. According to a recent estimate, the value of 100 megabytes of lost data is approximately $ 1 million. In a scenario where 43 percent of companies facing a data loss disaster end up bankrupt, data recovery is a must.

Reasons for Data Loss

Broadly speaking, the reasons for data loss can be classified into two categories, i.e. .:

1) Physical Damage

Storage media can be damaged for various reasons. Optical discs can have their data storage layer scratched or damaged due to mishandling, exposure to light, high temperatures, or humidity. The tapes can simply warp or break due to a faulty head or some other reason. Hard drives can suffer mechanical or electronic failure due to internal component damage. Most of the time, physical damage cannot be repaired by end users and often requires the services of expert data recovery technicians to recover lost data.

2) Logical damage

Logical damage occurs due to file system corruption. This can happen due to various reasons such as a malware attack, accidental deletion of important files or folders, a power spike, or electrostatic discharge. This leads to a flaw in the design of the program, so it responds inappropriately or may fail altogether. Sometimes logical errors can be corrected using DIY data recovery software. However, if the damage is substantial, you may need the services of a data recovery company.

Is lost Data Always Recoverable?

Most of the time, lost or deleted data can be recovered with a high success rate. Often times, when a file is deleted, it remains unharmed in the disk’s unallocated clusters and is recoverable. Sometimes even files that are overwritten can be recovered using highly sophisticated data recovery techniques. So, practically speaking, we rarely come across cases where the lost data is one hundred percent unrecoverable.

Fundamentals for Data Recovery

Due to ever-increasing demand, various data recovery companies have multiplied over the years. However, companies that are genuine and authentic can be counted on the fingers. Proper infrastructure (class 100 clean room facilities), trained technical staff, and custom tools are the must-haves for any good data recovery company. In addition, a bona fide data recovery company must have dedicated R&D support to offer a wide range of solutions to its customers.

So the next time you lose data, don’t panic or worry. Chances are, some good data recovery company can save the day.
