What Is Data Recovery?

Even before the inception of computing, keeping important information has always been an essential part of human civilization. It serves as a way to retrieve knowledge, records and many more that could have been lost elsewhere if not for effective methods of preservation and documentation.

But just like in the analog days when manual data preservation was prevalent, storing information in the digital age also comes with the risk of losing it. This is why data recovery plays a crucial role in modern computing. This article delves into how data recovery works, the tools and methods used, and why it is vital for safeguarding valuable digital information.

What is data recovery?

Data recovery pertains to retrieving information that may have been lost, corrupted, deleted, or inaccessible from data storage. This process may involve specialized software and techniques to scan storage devices, identify recoverable data, and restore it to its original state or a usable format.

Reasons for data recovery

Data recovery is performed for several reasons. Here are some of them:

• Accidental deletion. This is one of the most common reasons for data loss and information retrieval. It happens when files or folders are unintentionally removed from a storage device.
• Hardware failure. Most machines and devices are at risk of failing, and computers and storage devices are no different. Hardware failure occurs when machines and storage devices are rendered inoperable due to many factors, such as wear and tear, power surges, head crashes, and more.
• Software corruption. Software corruption can damage the file system or the data, making it inaccessible. This can happen due to software bugs, incomplete installations, or virus infections.
• Malware attacks. Malicious software may contain programs that can encrypt, delete, or corrupt data on your computer, causing important data and information to be deleted.
• Natural disasters. This refers to catastrophic events, such as acts of nature that may cause damage to storage devices and machines, leading to data loss.
• Human error. Human error is a significant cause of data loss. Mistakes like accidental formatting, incorrect file deletion, or improper handling of storage devices can lead to data loss.

How data recovery works

Data recovery is a process that undergoes multiple stages to execute. Here’s how data recovery works.

Data recovery methods

IT professionals performing data recovery may choose a method to accomplish the task:

• Software-based recovery. Involves using specialized software to recover data from logical damage or accidental deletion. Here are some examples of software-based recovery methods:
• File recovery software. Many types of software scan storage devices for deleted files in an attempt to retrieve them unscathed. This method is commonly used when recovering data that were accidentally deleted.
• Partition recovery software. There are also software and applications that can recover data from lost or damaged partitions on a hard drive. This retrieval method comes in handy when a partition table becomes corrupted or accidentally deleted.
• Disk imaging software. In instances of hardware failures or data corruption, disk imaging software can create an image of a storage device for data recovery.
• Hardware-based recovery. Hardware-based recovery is necessary when physical damage occurs to the storage device. It requires specialized equipment and techniques to access the damaged device and recover data. Here are some examples of hardware-based recovery methods:
• Clean room recovery. A clean room is a controlled environment that minimizes the risk of contamination. Data recovery specialists work in clean rooms to repair damaged storage devices, such as hard drives with physical damage.
• Data recovery labs. Data recovery labs have advanced tools and techniques to recover data from severely damaged storage devices.
• Specialized tools and techniques. Data recovery specialists use specialized tools and techniques, such as data recovery software, firmware repair, and micro-welding, to recover data from damaged devices.

Data recovery process

After determining the best method for starting the retrieval operations, IT teams can proceed to the next data retrieval process.

• Data assessment: This process involves identifying the cause of data loss. IT teams are also going to evaluate the severity of data loss.
• Data recovery: Data recovery is the step where data retrievers determine which appropriate techniques to implement to extract data from the storage device.
• Data analysis and repair: The retrieved data will also be checked for errors so IT teams can determine if corrupted files are still capable of being repaired.
• Data restore: This is the process where IT teams restore the recovered data to a usable format.

Data recovery best practices

You can apply several strategies to ensure a successful data recovery process, even before you need to operate. Here are some best practices for data recovery:

Doing regular backups

Implementing a regular backup strategy is one of the most effective ways to protect your data. This involves creating copies of your important data and storing them on external hard drives, cloud storage services, or other reliable media. Regularly backing up your data can minimize the impact of data loss and quickly restore your files if needed.

Proper handling of data storage

Physical data storage devices are susceptible to damage when not handled properly. Some ways to protect them are preventing physical shock, protecting them from extreme temperatures, keeping them away from magnetic fields, regularly checking for errors, and more.

Avoiding DIY recovery

While you may always err on the side of caution, it’s still a different conversation when doing data recovery, especially if you are not an expert. Avoid doing data recovery when unsure of what you are doing because this may lead to further data loss. Data recovery is a complex process requiring specialized knowledge and skills, so it’s best to leave the task to professionals to execute it successfully.

Relying on a reputable data recovery service

There are several types of data recovery services that you can employ based on use cases or the severity of data loss.

• Professional data recovery services

These recovery services cater to severe data loss that encompasses complex retrieval operations. There are also services that offer urgent data retrieval, prioritizing quick turnaround times for critical data loss. You can also look into secure services that cater to companies that keep financial information, medical records, and confidential data.

• DIY data recovery software

DIY data recovery software is a convenient solution for recovering lost data in various scenarios. Tools designed for accidental deletion can retrieve files mistakenly removed. For formatted drives, specialized software can recover data from hard drives, SSDs, or memory cards. Additionally, tools for corrupted files can repair damaged file systems and recover lost data. But then again, if you’re dealing with critical data loss, you might want to opt for professional data recovery services.

• Cloud-based data recovery services

Some organizations can rely on cloud-based data recovery services for several reasons. Some depend on services that offer remote data access, which allows them to access and recover their data from anywhere with an internet connection. Other services also offer real-time automatic data backup for continuous protection in case of data loss. Some services can help organizations recover their data in case of a disaster, such as a fire, flood, or cyberattack.

Conclusion

Data recovery is a process of retrieving data that may have been lost, corrupted, or deemed inaccessible. Retrieval of these data types may require complex procedures commonly done by IT professionals. There are services that offer data recovery depending on urgency, use cases, and the company’s specific needs. By understanding the common causes of data loss and implementing effective data recovery strategies, individuals and organizations can minimize the risk of data loss and protect their valuable information.
