Restoration of damaged raid arrays
In the world of distributed data storage on NAS devices such as Synology, QNAP, ASUSTOR, Western Digital, Thecus, TerraMaster, Buffalo and others, information recovery has become an integral part of security. This article brings together methods for recovering data from RAID NAS devices, including drive failure scenarios and simple file recovery without removing drives.
Which NAS operating system is better - Synology DSM or QNAP QTS? Both operating systems come with ready-made NAS devices from their manufacturers, Synology and QNAP, respectively. Let's compare these two operating systems - what they represent in general, and what possibilities they can offer for data storage.
OpenMediaVault (OMV) is a specialized operating system for independently assembled NAS storages. It is based on Debian Linux, one of the popular operating systems, and provides software for creating data storage based on various hard drive arrays. So, how can you recover data from a NAS storage created in OpenMediaVault?
The use of RAID arrays in NAS devices does not guarantee protection against failures and data loss. For instance, you may encounter a situation where the data on your Synology NAS has been corrupted, or deleted, or the hard drive has failed.
In such cases, it is important to quickly recover data from the NAS using specialized tools and techniques. In this article, we will walk through the process of data recovery from a Synology NAS DS415+ RAID and discuss the tools and approaches that can help you with this.
How to recover data from X-RAID Netgear? The technology of building an X-RAID array on Netgear ReadyNAS NAS devices has certain advantages but also has its own nuances. And when it comes to data recovery, it requires support from specialized programs. Let's take a look at how one of these programs works.
Even though they are regarded as data safety mechanisms, fail-tolerant RAID systems are still not perfect. Data can be lost even from arrays with high redundancy, and there is nothing to say about arrays with zero fault tolerance at all. Sometimes, important files can even be deleted by mistake. To recover data from RAID, you need special tools that support recovery operations for RAID systems, specifically. Let’s make a review of the top 7 tools and consider their pros and cons to choose the best one.
A specialized operating system TrueNAS is one of the best solutions to manage DIY NAS storage systems. However, it also has some downsides – for example, the data recovery process from a TrueNAS storage can be really complicated. Also, some data recovery tools don’t work with TrueNAS and its specific RAID arrays. Keep on reading for a review of popular data recovery products, and you’ll see which of them are really good of TrueNAS. In the process, we’ll find out how to recover data from TrueNAS-based NAS storage properly.
One of the important criteria for choosing a NAS (network attached storage) device is its ability to ensure data integrity using RAID arrays. However, to ensure reliable data protection, it is important to choose the correct RAID configuration. In this article, we will consider the implementation of RAID on different NAS devices, compare performance and reliability, and determine the optimal option for specific cases. We will also help you choose the most suitable file system to use in a RAID array on your NAS device.
