The popularity of NAS devices among professionals and individuals alike does not guarantee absolute reliability against data loss. In reality, the risks of hardware failure or accidental manipulation are constant. It is therefore up to you to learn about the various ways to recover your files and information.
Has important data from your NAS disappeared? Rest assured, recovering it is entirely possible. But how? In this article, you will learn more about QNAP NAS, the main causes of data loss, and the various solutions for recovering this data.
QNAP NAS: what is it?
The QNAP NAS is a multi-drive server enabling centralized data backup. This system is constantly online and accessible wherever you are. Unlike the external hard drive, which is considered an outdated and limited data storage system, this server is a modern and highly innovative solution.
Thanks to its QTS operating system, both efficient and user-friendly, the QNAP NAS server becomes a truly individual system that is configurable and simple to use. It integrates a variety of solutions including management features for backup, files, a media center, and more.
What are the main causes of data loss on this server?
The causes of NAS drive failures generally vary. Since QNAP has adopted conventional RAID configurations for its NAS servers, the most frequent cause of mechanical failure is the natural deterioration of the drives. However, these failures often lead to data loss. The main ones are:
Human error
On NAS or RAID systems, file loss mostly stems from human error. Formatting, uninstalling, or accidentally deleting the contents of a single drive frequently results in data loss.
Failure of NAS drives or the RAID system
RAID systems are designed to compensate for the malfunction of a hard drive, thanks to the other drives that make them up. Indeed, these additional hard drives make it possible to offset the failure. As a result, the malfunction of one of them can lead to a total failure.
Malfunctioning NAS controllers
NAS controller failures often result from mistakes made during reorganization or rebuilding. Corruption of the firmware or operating system can also cause file loss when the memory configuration is erased.
Incorrect firmware update
A faulty firmware update is a source of failures. For example, when an IT administrator clicks Update without taking the time to check the system. QTS, the operating system found on QNAP servers, can in some cases be wiped and lead to file loss. Before proceeding with an update, you should back up all your folders or files.
Power outage
A power outage, a power surge, or a sudden voltage fluctuation can damage a NAS system. Keep in mind that older RAID systems are very poorly resistant to voltage fluctuations. Indeed, a sudden change in voltage can disrupt the reinstallation process of a drive that is not synchronized with the RAID system. Moreover, this lack of synchronization can complicate recovery in the event of file loss.
Natural disasters
Flooding, contamination, or fire are phenomena that can severely damage your NAS drives. With the destruction of the server, the risk of losing your data is enormous.
Overheating
When a storage system overheats due to a lack of air conditioning in the server room or improper positioning during installation, file loss can occur.
What data recovery solutions are available?
Since file loss generally results from accidental manipulation or a failure, there are various recovery methods available. The best solution for restoring folders or files on a QNAP NAS server will depend on the type of failure and its scale. Here are a few data recovery solutions:
Recovery using the recycle bin
Were folders or files accidentally deleted from your NAS drive, or was the drive formatted or corrupted? You can recover the data using the recycle bin. In fact, a QNAP NAS server runs an operating system called QTS, which includes a recycle bin. However, it must have been enabled beforehand for restoration to be possible.
QNAP data recovery software
When you lose files stored on a QNAP NAS drive, using an application dedicated to file restoration can help. Given the abundance of such software available online, it is important to choose a file recovery app that is reliable and effective.
When choosing the software, also check its compatibility with QNAP servers and the types of files it can recover. In addition, you should check whether the chosen application is available for the operating system installed on your computer. Indeed, some software only works on Linux or Windows. Also note that the recovery process will vary depending on the application you install.
A professional NAS data recovery service
If your efforts to recover files from the server have not succeeded, it is best to entrust this task to a professional. This can be an independent external provider offering a lost data recovery service. To obtain a personalized service, simply get in touch with an expert found after thorough research online.
Furthermore, restoring data from a NAS system generally requires several operations, namely:
- Removing the hard drives that make up the server;
- Diagnosing the hard drive;
- Determining the NAS file system;
- Identifying the type of RAID system and its characteristics.
Since you are not equipped for this kind of task, use the services of a professional to carry out the complete recovery of data lost on the NAS system. They will then offer you a recovery solution based on the cause of the file loss and your needs. Worried about having to spend a large sum on these recovery services? Know that with a professional, you not only ensure the recovery of your files but also their security. What’s more, your NAS drives will be handled with care so that they are not damaged.
