What to Do When NAS Fails?
Table of Contents

Network Attached Storage (NAS) is the most widespread solution when there is a need to store large amounts of data or access valuable files across multiple devices. Network drives already have a built-in controller, so users can start using them as soon as they are plugged into your system.

Usually, NAS devices use several hard drives connected as a RAID array. These drives already have their processor, so they can be configured and programmed.  Businesses and individuals entrust their data to NAS devices due to its many advantages. However, as with any media, NAS is susceptible to failures.

What to Do When Facing a NAS Failure?

Facing a failure on a NAS device is complicated and stressful, as it often leads to data loss. When files becomes inaccessible, users try to solve this problem themselves. However, this approach to the problem is not right and can cause more harm than good.

There are many recovery tutorials on the Internet, but following them is very risky for a failed device. A user can severely worsen the situation by trying to repair the NAS drives in unspecialized facilities.

Using data recovery software on your storage device is also not recommended. Unverified tools can cause overwriting of your valuable files. In addition to overwriting, it can insert malware into the drives by making the case more complicated.

NAS devices usually have built-in rebuild features. It is essential to refrain from using these functions when facing a failure on a device. 

“Rebuild” or “Restore” processes tend to reinitialize the internal RAID array, which has destructive potential for your data. The drive’s “Restore” function usually creates a new, workable – but completely empty partition.

Hence, when noting any signs of malfunction from your NAS device, it is essential to power it down. If you continue to use the failed device, you risk damaging the valuable files stored on it. Hence, we recommend turning it off and not trying to restart it.

The next step is to contact a reputable data recovery company. NAS devices have a complicated infrastructure that only experienced engineers can handle.

To achieve the maximum results of file recovery, entrust your case to professionals. RAID Recovery Services has years of expertise working on various brands and models of NAS devices. Our technicians find an individual approach to each NAS data loss scenario.

Types of NAS failure

Types of NAS Failure
Type of NAS Failure Description
Hardware Failure Failure of physical components such as hard drives, power supplies, or cooling systems.
Software Failure Malfunction or corruption of the NAS operating system or firmware.
Network Failure Issues with network connectivity or configuration, preventing access to the NAS.
Configuration Error Incorrect settings or misconfigurations leading to operational problems.
Data Corruption Data stored on the NAS becomes corrupted, possibly due to hardware or software issues.
Power Outage Loss of power leading to unexpected shutdowns and potential data loss or corruption.
Security Breach Unauthorized access to the NAS, resulting in data theft, modification, or deletion.
Environmental Damage Damage caused by factors such as water, fire, or extreme temperatures affecting NAS hardware.

Our NAS Data Recovery Process

The RAID Recovery Services team treats each case differently and approaches it with special care. As soon as we receive the device at our facility, we start its evaluation. Our engineers thoroughly review the device to find out all the details regarding your case. Based on this information, we select the most suitable data recovery strategy for your device.


At the end of the evaluation, we provide clients with the case details, including the cause of data loss, the level of damage, and a service quote. We offer our customers various data recovery options to meet their needs, deadlines, and budgets.

Our engineers start to recover data from NAS only after receiving approval from a customer. 

We work on the media in specialized facilities, using state-of-the-art recovery tools. We aim to perform a safe and professional data recovery process and do everything for it. RAID Recovery Services regularly renews data recovery equipment, so our facility has cutting-edge technologies for successful recovery.

In addition, our technicians constantly attend qualification courses and recovery trainings so that they can handle any data loss situation. Therefore, we provide data recovery regardless of the operating system, file system, RAID configuration, and storage capacity of the device.

After completing all the data recovery procedures, we schedule a verification session for our clients to submit restored files. After a customer approves the result, we return all the data and completely delete it from our servers. Hence, we support the highest level of confidentiality and security. Our clients can keep peace of mind when entrusting their sensitive data to us.

Data Loss Prevention for NAS

To prevent data loss in NAS (Network-Attached Storage) systems, follow these critical steps:

Regular Backups

Set up a scheduled backup system to copy data to multiple locations, such as another NAS, an external hard drive, or a cloud service. This strategy provides redundancy, protecting against data loss from hardware failures or disasters. Regularly test these backups to ensure they can be restored accurately.

RAID Configuration

Use RAID setups to minimize data loss from hardware failures. This method combines several disk drives, distributing data to enhance performance and reliability. If a disk fails, the system automatically switches to another, avoiding data loss and significant downtime. This maintains operations and protects key information, making RAID essential for data protection against hardware problems.

Update Firmware Regularly

Regularly update your NAS firmware for the latest security patches and performance boosts. Frequent updates protect your data from new threats and improve system efficiency. Don’t neglect this key maintenance step. It greatly boosts your NAS’s reliability and lifespan.

Monitor NAS Health

Employ native or external tools to monitor your NAS’s condition, looking for indicators of disk malfunction or system problems. Routine upkeep, including software upgrades and backups, plays a crucial role in averting data loss. Stay current with the newest security risks and ensure your NAS is safeguarded against potential weaknesses.

Use Power Surge Protectors

Connect your NAS to a surge protector to shield it from power surges, preventing data loss and hardware damage. Surge protectors fend off voltage spikes, dodging expensive repairs or data recovery. This minor investment protects your data and prolongs your NAS system’s lifespan, providing substantial security benefits.

Physical Security

Secure your NAS against theft, fire, and water damage. Install surveillance cameras and alarms for extra security. Back up data offsite regularly to prevent data loss. Store in fireproof and waterproof safes or cabinets for more protection. Regular checks can spot and prevent potential risks early.

Access Controls

Implement strict access controls to block unauthorized access, preventing data loss or corruption. Update security measures regularly to counter new threats. Train employees on security importance and their role in protecting data. Add multi-factor authentication for an extra layer of security against breaches.

Offsite Backups

In addition to local backups, store data offsite or in the cloud to protect against local disasters. A multi-layered backup strategy offers redundancy, crucial for recovery from hardware failures, natural disasters, or cyberattacks. Using diverse storage solutions reduces the risk of total data loss and enhances data security.
