Types of Data Recovery

Modern businesses these days depend on data the most for their personal workflow and routine operations. Data is what runs their routine operations, be it critical business documents, customer records, or anything else. The panic starts when businesses lose data by accident, hardware failure, or cyberattacks. 

This is what makes it key for businesses to understand the types of data recovery. Whether it is the enterprise-level servers or other devices, it is key for businesses to understand the right data recovery method so that the chances of recovering the lost data are increased. 

Dive deep into this blog to understand the different types of data recovery, how they work, when to use them, and ways to avoid data loss in the future. Understanding all of this is key for businesses to ensure business continuity. 

Data Recovery

Data recovery is the process of recovering lost data from storage devices like computers, servers, SSDs, hard drives, smartphones, and cloud accounts. It is not that only particular-sized businesses face the risk of data loss. The small businesses, enterprises, and startups all face the risks of data loss due to human error, hardware malfunction, ransomware attacks, system crashes, and natural disasters. 

The users can only select the right data recovery method by understanding the types of data recovery and the loss scenario. But here’s the thing. The businesses need to act quickly in the event of data loss to increase their chances of recovering the lost data. 

How Data Recovery Works?

The most common mistake businesses make is jumping straight to the types of data recovery. Instead, the businesses first need to understand how the storage devices handle data. The file doesn’t disappear immediately after you delete it. What happens is that the system marks the space as “available.” The actual data stays on the disk only. 

This means that if you respond quickly, then the data recovery is possible. But there are certain factors that determine the success of the data recovery, which are mentioned below. 

• Types of storage devices
• File system
• Damage extent
• Is TRIM enabled or not
• DIY tools 

The businesses can choose the correct data recovery method once they know all these factors, as this determines whether the recovery will be possible or not. 

Types of Data Recovery

Nothing matters more to businesses than the data. It is the data that keeps the routine operations of the business running smoothly and also builds trust among the customers that their information is safe. But there’s always a risk of losing the data to cyberattacks, data breaches, and hardware failures. 

Cyberattacks and data breaches have become so common that almost any business can fall victim to them. But there are some methods using which businesses can recover their lost data. Each of the methods applies to the specific loss scenarios and not otherwise. Here’s a sneak peek at the types of data recovery. 

File-level data recovery

The foremost type of data recovery is file-level data recovery. It is not only the common but the simplest way to recover the lost data. This method enables the businesses to restore the individual files that got accidentally deleted, were removed by malware, or were hidden or corrupted. 

The data recovery tools scan the storage device for the data signatures and then rebuild the missing files. This method works best for restoring the documents and files deleted by the users, but not for severe damage. 

Partition Recovery

The next type of data recovery method is partition recovery. The partitions are the logical divisions on the hard drive, but these disappear due to formatting issues, table corruption, faulty installation, or malware. This reconstructs the lost partitions and gives businesses access to their data. 

This method works best for businesses when the drive shows “unallocated space”, the wrong partition formatting, and the OS is unable to boot due to a missing system partition. This method requires professional tools to make the recovery possible and is technical. 

Operating System Recovery 

Next comes the operating system recovery. The business’s data is not lost when the system refuses to boot. In fact, the data stays safe all the while. The businesses can recover the data using the operating system recovery method by doing the following: 

• Fixing the corrupted system files
• Restoring boot configuration
• Reinstalling OS
• Recovery disks 

The situations when the windows don’t start, the registry files are corrupted, and the bootloader fails are when this method works the best. The businesses need to be careful when performing this to avoid overwriting the important files. 

Hard drive recovery

There are two main types of data recovery included under the hard drive recovery. One is logical, and the other is physical. The logical hard drive recovery is done when the logical issues disrupt the access to the files, but do not damage the disk physically. 

The common causes of the logical issues include accidental formatting, malware, and broken directory structure. The tools are used to scan the disk and then rebuild the missing metadata. Then comes the physical hard drive recovery. 

It is the most severe type of data loss that businesses face. The data recovery requires a cleanroom, replacement parts, and advanced imaging technology. The data recovery from the physical hard drive damage is the most complex and expensive one. But this matters as the business data is sensitive. 

SSD Data Recovery

Then there’s SSD data recovery. The best part about the SSD data recovery method is that it is fast and more durable than the other methods. But here’s the thing. Recovering data from SSDs compared to others is complex because of the TRIM command, complex algorithms, and wear-leveling. 

The businesses can recover the lost data when the SSD controller fails, the file system corrupts, or firmware issues pop up. 

RAID Data Recovery

RAID refers to Redundant Array of Independent Disks. This is commonly used in servers for speed, redundancy, and sometimes for both. The RAID failures include physical disk failure, logical corruption, and multiple drive failures. 

The data recovery involves rebuilding the RAID configuration, reconstructing data, and extracting data from each disk. The businesses need to make use of different data recovery methods for the different RAID setups. 

Server Data Recovery

The next type of data recovery method is server data recovery. A large amount of businesses’ sensitive data and information is stored in the servers, just like databases, emails, virtual machines, or application data. 

The businesses can recover the lost data from the servers by restoring the RAID arrays, rebuilding database files, and extracting data from the damaged disks. This is one of the specialized data recovery methods used by the enterprises. 

Cloud Data Recovery

Businesses think that the cloud platforms have no risk of data loss, but even the cloud platforms can experience accidental deletions. This is the reason most cloud service providers offer version history, recycle bin, activity logs, and recovery options on the admin level. 

The businesses can restore the deleted files, corrupted backups, and overwritten backups with the cloud recovery. The outages that take place because of the provider, which is rare, require deeper restoration. 

Email Data Recovery

Nearly every business uses emails these days for communication and collaboration with not only the team but the customers as well. This makes the email recovery crucial for businesses by making use of the Outlook, Gmail, or enterprise mail servers.

The issues businesses face in emails include corrupted files, accidental deletion, permanent and server migration errors. What happens is that tools reconstruct the mailbox files and restore the attachments and messages. 

Database Recovery

Most businesses’ databases, such as SQL, MySQL, and others, fail due to system crashes or corruption. The data recovery then takes place by repairing the corrupted tables, rebuilding indexes, and point in time restoration. This is a sensitive type of data recovery for businesses. 

Encrypted Data Recovery

The encrypted data recovery is next. The data stays protected via encryption, but it makes data recovery nearly impossible. The data recovery from this only happens through the encryption key, password, and security certificates. Even the data recovery experts cannot recover the data without these. 

Forensic Data Recovery

The businesses that have experienced cybercrime can make use of this data recovery method. This method enables businesses to uncover the deleted files, hidden data, and user activity. But recovering data through this requires special tools and strict procedures. 

Things to Keep in Mind When Choosing The Right Data Recovery Method

There are so many different types of data recovery options available that it becomes difficult to decide which data recovery method to choose and which not to. The data loss can turn severe and complicated if businesses choose the wrong approach. This is why it is important to analyze the situation carefully before attempting the data recovery. 

Identify the type of data loss 

The first thing is to identify the type of data loss, like whether the data loss took place accidentally, logical damage, physical damage, or is a complex system failure. It is because different types of failures require different data recovery methods. 

For instance, the businesses can opt for the File-level data recovery if the data has been accidentally deleted. But if it is the logical damage, then the logical data recovery or partition recovery might work the best. 

Evaluate the significance of data

All lost data is equally important, which makes it vital for businesses to evaluate the data that is important and that is not. This requires businesses to evaluate whether the data is critical and encrypted or not. 

Most of the time, businesses deal with sensitive information, which makes it vital to hire data recovery specialists only for the data recovery instead of doing it yourself and taking a huge risk. 

Check the condition of the device

The device condition also needs to be checked before choosing the data recovery method. The businesses can only use the DIY tools when the computer recognizes the device, files are deleted, but the drive is healthy, and the storage still works. 

But there are times when businesses need to avoid using the DIY tools completely, like when the SSD is not recognized, visible damage, an overheating drive, or a drive not detected in BIOS. It is recommended to opt for professional data recovery only in these scenarios. 

Pick between DIY and professional data recovery

There are both options available: DIY and professional data recovery. The DIY recovery is best when the data has been accidentally deleted, you only need partial data, and the device is not physically damaged. 

But the businesses need to opt for professional data recovery when the disk is physically damaged, multiple drives have failed, and the information is critical. The professionals not only have the expertise but also the tools to make the data recovery possible. 

Pay heed to storage technology

The storage devices also need to be checked before choosing the right data recovery method. It is because different storage devices need different methods. The logical and physical recovery would work best for HDD. 

If the storage device is SSD, then the businesses need to have experts if the controller or the firmware fails, as it is more complex. It is crucial to understand the devices to choose the right data recovery method. 

Assess the risks 

The next step is assessing the risks. It is because some recovery actions can permanently reduce the data recovery chances. The businesses need to avoid installing software on the same drive, writing new data to the affected device, and using the internet “fix tools” to get rid of the physical issues. 

The businesses need to avoid all of this, as this increases the risk of overwriting or damaging the existing recoverable data. 

Calculating the cost vs value of data 

This is the most significant thing where businesses need to calculate the cost vs the value of the data. The businesses need to see if the cost of leaving the data is higher than the recovery cost or if downtime is affecting the business operations. 

Act quickly 

Not many businesses know this, but the chances of data recovery reduce the longer you wait. The businesses can recover the files longer unless overwritten for HDDs, but for SSDs, TRIM removes deleted data right away. So, businesses need to act fast to make data recovery a big success when choosing the right type of recovery. 

Conclusion

This is everything about the different types of data recovery methods for businesses can use to recover the lost data and continue with their routine operations. It is always better to get professional data recovery services to ensure the data recovery success and be at peace of mind.
