Data recovery involves the process (and the software used) of restoring access to files that have been lost due to storage corruption, user error, or unexpected outages by reconstructing the remaining fragments, rebuilding from what remains, or utilizing backups.
In essence, it is the method of retrieving lost, damaged, accidentally deleted, or otherwise inaccessible data to servers, computers, smartphones, or storage devices (or transferring it to a new device if the original device is unusable).
Typically, data is retrieved from an off-site backup copy. The more recent the backup version, the better the chances of data recovery in the event of loss or corruption.
Data recovery also includes the process of "undeleting" files that a user might have erased by mistake by restoring their system formatting. It also offers specialized data recovery services for damaged drives.
Data recovery is necessary in scenarios of data loss due to:
Natural disasters, such as fires, floods, earthquakes, and power outages
Errors in application software, like logical mistakes in database access
User negligence or accidental deletion of data or folders
Deterioration or intentional tampering of data (due to malicious or infected software and files)
Outdated software lacking security patches
Incompatible third-party plugins or applications
Considering the impact of data loss, data recovery methods and software solutions are crucial for risk mitigation and maintaining business continuity.

Types of Data Recovery
Data recovery can be categorized into various types:
Logical data recovery: This is performed when the data recovery issue affects the computer but not the hard disk itself. This happens when a disk is still operational but some data is missing.
Physical data recovery: This occurs when the hard disk has physical damage. There are organizations that specialize in data recovery for physically affected disks. They can help reconstruct faulty firmware so data can be read and transferred.
Hard drive recovery: Recovering data from hard drives is perhaps the most common data recovery technique, though it is also the most complex. Users should consult a hard disk recovery service and regularly back up important data.
Optical recovery: CDs, DVDs, and other laser-written media are referred to as optical storage. Using data recovery solutions that specialize in optical storage offers the best chance of retrieving lost data from optical media.
Instant data recovery: In this recovery method, when data is lost, the user is immediately redirected to a backup server. They have nearly instant access to a snapshot of their workload, while IT handles the full restoration in the background.

Process of Data Recovery
If you've experienced file loss or wish to prepare for a future emergency, here are the steps to follow:
1. Stay calm
Initially, users need to remain composed and refrain from hastily handling or worsening the problem. The primary step is to ensure that no further changes are made to the storage media where the lost data was located. Also, do not save any data on the compromised drive. If the system (boot) disk, which boots the operating system, is damaged, it is best to simply shut down the computer. All additional preparations for data recovery software should be done on a different computer.
2. Conduct Your Research
The following step involves gaining more knowledge about data recovery. There are numerous online resources available to help you understand the data recovery process and what to expect in your particular situation. You can also evaluate the chances of successfully recovering files in various scenarios.
3. Temporarily Disable the Affected Device
Upon discovering a data loss incident, stop using any affected devices immediately. In some cases, it is possible to retrieve corrupted or lost files from the hard drive before they are overwritten. However, the risk of overwriting increases if users continue to use the disk. If the data loss resulted from an event like a fire or flood, users should refrain from using the affected equipment until it has been inspected and deemed safe.

4. Identify Symptoms
When data loss occurs, there are several external signs that indicate a problem. Indicators of data loss from the hard drive include:
If your system no longer recognizes the hard drive or if it is listed with an unusual name, the hard drive may be facing issues.
The hard drive makes unusual noises, clicks, or operates very slowly.
Bad blocks frequently appear on your hard drive.
5. Record the Situation
Understanding exactly what caused the data loss is crucial for choosing the best recovery approach. Gathering as much information as possible will also streamline the process and help prevent a similar issue in the future. Have there been recent changes to the IT infrastructure? Is a new employee accessing your data? What symptoms did you observe? This information can aid you or the data recovery specialist later.
6. Select Your Data Recovery Method
Once you’ve identified the causes of the data loss, it’s time to start the recovery process. If you have been consistently creating backups, the easiest solution is to restore all data from these backups. If there is no backup system, users should consider disk recovery as an alternative. Disk recovery can be attempted manually by downloading specialized software or by seeking professional help.
7. Consult an Expert
After identifying the cause of the data loss and the most efficient recovery method, you may seek help from a data recovery expert. If you have dedicated software installed, the software provider can assist you. While you might attempt data recovery on your own, it is always advisable to consult an expert, especially if you’ve lost a substantial amount of critical data. An unsuccessful recovery attempt might cause more damage, leading to additional costs.
8. Allocate Space for Recovered Data
Working with image files (a representation of the storage system and its contents) is preferable to working with physical disks for data retrieval. This protects the data from accidental corruption. This step involves preparing enough storage space for recovered data and images. It is strictly prohibited to attempt to save recovered data on the original disks.
9. Implement Preventive Measures
After recovering as much data as possible, it is important to reflect on the lessons learned. Consider the reasons for the loss and take steps to prevent it from reoccurring.
If there is a security vulnerability in the network, you may need the assistance of security experts. If environmental factors compromise storage equipment, it might be wise to back up the data remotely. Consider exploring managed IT services if you struggle to protect large volumes of data and complex, diverse file formats.
Data Recovery Software
Data recovery software is a type of application designed to help retrieve lost, damaged, or inaccessible data from storage devices. Its purpose is to analyze, scan, locate, recover, and back up data from deleted, damaged, or formatted areas or from specified locations on the storage device.
In 2021, the global data recovery and backup market, which includes data recovery software, was valued at $10.61 billion. According to the Data Backup and Recovery Market: Global Overview and Forecast (2022-2029) report by Maximize Market Research, this sector's revenue is expected to grow by 10.3% from 2022 to 2029, reaching around $23.24 billion.
What is data recovery software?

How to choose data recovery software?
When selecting the best data recovery software, consider the following criteria:
Compatibility: Initially, disk recovery software should work with your operating system. Users should look for a service that is regularly updated to support various operating system versions and features. Moreover, the software should be capable of recovering lost data from file systems used in both internal and external storage media, such as NTFS, FAT, FAT32, exFAT, HFS+, APFS, ext2/3/4, among others.
Prompt support: Access to technical support is crucial if issues arise while using the software. Whether through phone, email, or a support ticket, there must be a way to receive quick help if you encounter difficulties retrieving lost data. This is especially important in emergency situations.
Credibility and reliability: Malicious entities can embed malware in recovery software to gain access to a user's computer during a crisis. It is generally safer to download software directly from the developer’s website rather than from third-party distributor sites.
Performance: The most effective data recovery solutions should successfully recover all deleted files and deliver on their promises. Unfortunately, developers often make exaggerated claims, so reviewing feedback from actual users and expert reviewers should be a key part of the selection process.
The likelihood of successfully retrieving deleted files using software from a disk-based storage device is closely linked to the device’s use since the data was lost.
Ideally, users should stop using devices immediately after noticing data loss, though this may not always be feasible. This factor should be taken into account when assessing the effectiveness of a data recovery tool.
Furthermore, no commercially available software can recover data that has been overwritten. A file is considered overwritten if:
The file occupying a certain storage space is marked as “deleted.”
Its storage space is marked as “available” for storing new files.
New data is written in the same location as the file.
Therefore, it is highly recommended that users regularly back up their computers and all important data, using data recovery software only as a last resort in emergencies.
Takeaway
Data recovery software is a multi-billion dollar industry for a reason. As enterprise data production increases and its importance to businesses grows, there must be a way to recover files, folders, and partitions that might have been accidentally deleted or lost due to unforeseen events. Data recovery software fulfills this critical role and, except in rare cases, ensures that lost data can be recovered.
