NAS Data Loss and Failure

Network-Attached Storage is one of the most reliable ways to store your valuable information. Both individuals and businesses rely heavily on NAS devices as essential tools. This system provides its user with a cost-effective performance, flexible options, centralized storage and constant access to their files. 

However, despite their convenience and efficiency, NAS data loss and failures can pose important challenges, potentially leading to valuable data being compromised or lost. In this blog, we’ll delve into the causes of NAS data loss and failures, explore preventative measures to mitigate risks, and discuss techniques for data recovery in case of an unfortunate event.

Causes of NAS Failure

Like any technological device, NAS systems are susceptible to different types of failures that can endanger your data. Comprehending the underlying causes of NAS failures is critical for both prevention and preparedness. Let’s explore some of the common causes of NAS failure and how they can affect data security and accessibility.

Human Error

Human failure is one of the most frequent reasons for losing data on the Network Attached Storage. Files' inaccessibility is often a result of accidental formatting, data leaks, reinstallation, or overwriting.

Power Failure

Data loss can occur unexpectedly due to overvoltage or voltage fluctuations. It usually happens without warning, so there might be no chance to protect your sensitive files from irreversible data loss.


Without a proper cooling system, overheating is unavoidable. This can eventually lead to drive failure, resulting in data loss. Hence, it is essential to monitor the environment in which NAS is stored.

Natural Disasters

Fire damage, contamination, and liquid damage can damage a NAS device in seconds. To avoid a severe data loss situation, the device needs immediate attention from experts.

Defective Controllers of NAS

Faulty system rebuilds and reorganizations could result in defective controllers. Due to the faulty controllers, a data loss on your Network Attached Storage can occur.

Mechanical Malfunction

NAS systems have an infrastructure that will help with a failure of a single hard drive. The remaining drives will compensate for the drive malfunction, resulting in data loss.

For any data storage device user, it is essential to protect it from any threats and secure sensitive data stored on it. There are several actions that can help with this mission. 

How to Minimize Risks of Data Loss on NAS

Manage Access Rights. NAS allows providing several users access to essential data. However, there is a need to control this access. This way, you can avoid any human errors with your valuable data.

Make Regular Backups. Backing up your files is a recommendation for any device, especially NAS. It is also better to spatially separate and encrypt the backup device in case of a natural disaster. 

Suitable Infrastructure. A NAS is typically set up with a RAID configuration. Hence, choosing a RAID suitable for your device would be beneficial. So, go with a RAID level which provides data security.

Frequent Checks. Regular monitoring of your device and data backup systems is a step you should take to ensure that your files are safe. Thus, we recommend regular inspections of your device.

Suitable Location for NAS. When maintaining a NAS, every user should pay attention to its location. In case of a natural disaster or main device malfunction, all the data stored on NAS will remain protected. 

Recognize the Emergency. It is essential to notice the problem on time to avoid data loss due to the NAS’s incorrect operation. Managing the system and periodically checking its performance can be helpful.

NAS Drive Failure Rates

The failure rate of NAS drives can vary depending on several factors such as brand, model, usage, and environmental conditions. According to a study conducted by Backblaze in 2020, which analyzed the failure rates of various hard drives including NAS drives, the average annualized failure rate for NAS drives was 0.93%, which is lower than the overall average failure rate for all hard drives analyzed in the study (1.58%).

However, it’s worth noting that this is just one study, and failure rates can vary significantly depending on various factors.

It’s important to choose a reliable, high-quality NAS drive from a reputable brand and use it within recommended operating conditions to minimize the risk of drive failures. It’s also crucial to regularly back up your data to other storage devices or the cloud to prevent permanent data loss in case of a drive failure.
