A network storage for NAS for short is a computer device used as a file server to let various client devices access certain data. Usually, such devices are based on RAID technology, which enables them to combine several drives into one big storage space, as well as improve reliability and data security. However, even the most reliable RAID type in the world cannot prevent data loss completely. The chances of hardware and software errors, run configuration, accidental removal of files or disk formatting depend very little on how reliable your RAID setup is, and any of these scenarios may result in losing an entire pool of very important information. Recovering data from an S system involves taking the device apart, connecting the disk directly to another computer, and using specialized data recovery software to retrieve the information. NAS devices usually run on Linux, so their volumes are formatted in Linux-supported file systems such as EXT, XFS, and BetterFS. When choosing a data recovery tool, make sure to check file system support features. In today's video, we will explore a step-by-step data recovery process with the server WD-Share Space supporting the installation of four hard disks, module WD-A4NC40000. For starters, let's find out how to build a RAID array, for example, a RAID5 system. Open the Management menu for NAS WD-Share Space, then go to Advanced Mode, jump to the tab Storage, then click on the tile for Volume and RAID Management. By default, after installation of the operating system, it creates a spanned volume, with all the disks connected to the device at the moment. In other words, all available disks are combined into one. To change the RAID level, select the one you prefer. In my case, it is RAID5. Click Submit to proceed. You see the warning that all data will be erased, and it takes 16 to 17 hours to rebuild the RAID5 volume. Click OK. The rebuilding process begins. Note that the RAID configuration has been changed successfully, resinking and formatting is in progress. Here is the RAID5 volume, consisting of three disks, and the last column displays its status – Recovery. All you do now is wait for the process to be awkward. Then create a shared folder and write your data to the disk. While the RAID system is being rebuilt, let's enable the FTP network protocol to access the storage. Open the tab Network, jump to Services, and enable FTP by checking the corresponding box. Then click Submit. When the disk array is rebuilt, you will be able to create shared folders. Open Storage, jump to Folder Shares, click the plus button to add a new folder, give the name for this directory, some description, check Network Services, and click Submit to confirm your choices. Now it's time to configure access to this shared folder. I will enable public access by checking this box and clicking Submit. After that, it becomes accessible, so you can go to the network drive and write your data there. High-grade software failures, product configuration, accidental removal, or formatting may cause a major data loss from disk storage inside your NAS device. In any of these situations, you will need a reliable tool to get your information back. Headwind RAID Recovery is a comprehensive solution for NAS data recovery to help you restore your files in several different scenarios. The program supports the most popular file systems including those used in NAS devices. It features an automatic advanced scan mechanism that will file the information needed for recovery, such as RAID first sector number, block size, number, and order of disks. NAS information can be recovered based on single drive solutions and large disk arrays combined into various RAID systems. Bear in mind that before starting data recovery operations, you should prepare some free disk space with the capacity equal to the amount of data you are planning to recover from your NAS. Take the disks out of the NAS device and connect them to a Windows computer. Make sure that all disks are recognized by the Windows integrated disk management utility. Right-click on the Start menu and select Disk Management. If you are suggested to initialize the disks, don't agree. Disk can erase the remaining data for good. If you are trying to recover data from a RAID 5 system and the motherboard of the computer where you want to connect the disks doesn't have enough setup ports for all those hard disks, you can connect all but one disk because this RAID type remains operable even if one of the disks is missing. Install and run Hetman RAID Recovery. Thanks to its automatic scan feature, the utility will analyze the disks, read their service information, and rebuild the damaged RAID system. The brief RAID information is displayed below. If the program has read it correctly, if the properties were detected with errors, you'll have to build the array manually in the RAID constructor. Right-click on the disk and open its properties to see more details. Select the scan type and start the analysis. The program will analyze the disks and display their contents when the operation is complete. As you can see, it has found all the data stored on the disk array, and in the case with RAID 5, everything works even though one disk is missing. Select the files you want to recover, click Recovery, select what you want to save them, and click Recovery again. When the recovery process is over, you will find all of the files in the folder you have chosen. This program can also recover data after disk formatting or accidental removal of files. After the scan is over, you will see the deleted files. They are marked with the red cross. To help you search for specific photos, videos and documents, more efficiently, there is a nice preview feature. Select and recover accidental deleted data. When scanning a RAID that used to have an operating system, the program shows you several disk arrays, a mirror RAID containing the operating system, and a RAID 5 containing the data. If you want to recover information from a system folder, scan the mirror RAID which stores system files. When a RAID recover is very easy to use, it will automatically find the information needed for recovery such as RAID for sector number, block size, number, and order of disks. When a disk is damaged or service information is erased, the program may have difficulties with rebuilding the RAID automatically. However, you can do it manually, with the RAID constructor if you know the properties of this damaged array. Open the RAID constructor and select Manual node. In filling all the information you know, the RAID type, block order and size, add the disks it used to include, use the arrows to set their order, and replace the missing disks with empty drives by clicking the plus button. Usually, if you give correct properties, the newly built RAID system has at least one partition. Expand it to check for the folders that you need. If the folders you are looking for are displayed, then you have built this RAID properly. When all the properties are given, click Add for the RAID system to appear in the Drive Manager. For recovery, scan the array you have just added, look for the files you need, select and recount them. And that is all for now. Hopefully, this video was useful.
