 Hello everybody! Watch this video to find out how to recover data from RAID1 and RAID0 based on QNAP TS2 19P Plus network attached storage, how to recover accidental or remote files from the trash bin, what to do if this option is inactive, and how to put things right if there is no access to the disks in this array, because either the NAS is broken or the RAID is degraded. This QNAP NAS model is designed to use two hard disks. To improve resilience and data safety, such devices enable you to create RAID systems of various times. However, even the most reliable storage systems may encounter emergencies like accidental and deletional files, formatting or damaging the hard disk, system errors, controller failures and other hardware issues, which may result in loss of important data. This specific model supports two RAID times – RAID1 and RAID0, as well as JBOT, which is sometimes referred to as linear RAID. Technically, it isn't RAID at all. In the end, redundancy in this NAS is only achieved by using a mirrored RAID. But if one of the disks fails in either RAID0 or JBOT, a part of the information is bound to be lost. In today's video, we will explore a situation when the NAS is broken. All the files are still on the disks, but it's impossible to retrieve them unless you use a specialized software tool. The matter is that a NAS storage device uses its own operating system which builds the RAID in a certain way and then writes data to its disks. Even when the hard disks are connected to another storage device or computer, the condition cannot be restored. For example, when the disks are connected to a Windows computer, you will see some partitions with an unrecognized file system. Another possible case is that the operating system will suggest initializing them in the Disk Management app, which is going to erase all the data, still remaining on the disks. In the end, you are going to lose access to the files or even lose them forever. In a Linux operating system, the disk partitions will be displayed as Linux RAID, and the option to mount is unavailable. You need to remember that if you choose to initialize the hard disks in Windows or modify the volume in Linux, this action can erase all the information, and it will make recovery very difficult. So never take any steps involving the hard disks unless you really know what you're doing, because there is a risk of losing your data permanently. To retrieve the information from the hard disks, you will need a special tool to rebuild a RAID system and restore access to the files which are stored inside the Disk RAID. For better understanding of how a Disk RAID is built, let's explore the process of creating a RAID system on this specific device. When you perform initial configuration, at stage 5, you will be suggested to configure the way your data is stored. The hard disks to be included into the array are already selected, so you should look down and select one of the RAID types RAID 1, RAID 0 or J-Bot. Select the necessary RAID type and click Next. If you want to change the existing RAID, you'll have to remove the previously created volumes first. To do it, open the menu, Storage Manager, now select all volumes and click Remove. As a result, you will see a warning window saying that all data will be removed. Click OK to confirm it. Now create a RAID with the hard disks. Click on the Create button above. Select the array type and click Next. Choose the disks and click Create. Now the system will display a warning that all hard disks will be erased. Click OK to confirm it. After that, the process of building and initializing the array begins. In the end, a new volume appears. If you have accidentally removed important files from the NAS, the first thing you should do is to check if the Network Recycle Bin option is enabled. This option will help you retrieve the previously deleted files. Luckily, in this NAS model, the Recycle Bin feature is activated by default. In order to restore accidentally deleted files from the Recycle Bin folder, open File Station. Go to the directory where your data was stored and open the bin by clicking on Recycle. Now open the directory where the data was stored. Select the files which you need to restore. Click on the Range Shape button. Select Recover and Yes to confirm it. After that, the files will reappear in the folder from which they were removed. Before restoring files with a specialized software tool, make sure that your deleted files are not stored in the Network Recycle Bin. To see if such option is enabled for this folder, go to Control Panel, Shared Folders and open its settings by clicking on the Edit button. The option to enable Network Recycle Bin must be checked, only in this case you'll be able to restore the data accidentally removed from the storage system. If you fail to retrieve files from the Recycle Bin and you don't have a backup or the storage system is broken so the rate has crashed and you can't access the data, your information can still be saved with a data recovery tool. If you lost access to rate data because the storage device broke down, the rate was misconfigured or rebuilt. Or if you deleted some files or accidentally formatted the hard disks, just download the specialized data recovery tool called Hetman Rate Recovery. This program supports all popular file systems and rate types and it will automatically rebuild the damaged rate with the available hard disks so that you'll be able to retrieve the necessary data. To start the recovery process, take the drives out of the storage device and connect them directly to the motherboard or Windows computer. If one of the hard disks breaks down, you can lose a part of your data depending on the rate level and this data is impossible to recover. If your using rate 0 and 1 hard disk is down, some information will be lost for good. The point is that this rate type is meant for higher performance, which is achieved through striping. It means that data is written to other disk imports which provides users with higher input output performance at a low cost. At the same time, though, it gives you no redundancy at all. So if that's your case, be ready to face the bitter truth – you won't be able to recover all your stuff. When the hard disks are connected, and the program starts, it will automatically scan the disks and rebuild the damaged rate. Below, you will see detailed information on the rate which was built. Right-click on the volume and choose Open. Select the scan type, file scan or full analysis. For full analysis, you need to specify the file system type used for the hard disks. This is the process where you command running a file scan. If the program can't find the missing files, then go back to the main menu and start full analysis. Right-click on the volume and choose Analyze again. Full analysis – choose the file system. When the scan is over, open the folder where the lost files were stored. This program retains the entire structure and file name, so it will be easy to find their required items and you can use the preview window to see their contents. Select all the items you want to recover and click the Recovery button. Specify where to save the data, choose the disk and folder, click Recovery and finish. You will find the recovered files in the folder you have chosen. If you use an ISCSI connection, you accidentally removed some data from the network drive and you failed to restore it from the network recycle bin, headwind partition recovery will help you. When files are deleted from a network drive, you don't need to power off the network-attached storage and take out the hard disks. The point is that Windows shows a network ISCSI drive as a physical one, so that you can scan it with the Recovery tool as if it were a physical hard disk. This way, you can recover data only if the storage device is operable and you have access to the network drive, otherwise you'll have to use the first method. Start the program and scan the volume. As you can see, the program had no difficulty in finding the deleted files. They are marked with the red cross and their contents can be displayed in the preview window. Select and recover the files you need. Well, you can see that it's not so difficult to recover data from an S, and the most important thing is to sync before you act, since rush actions may cause loss of all your data. And if you lost access to the disks inside the array, don't try to reconfigure it in order to restore its operability. This process involves formatting the hard disks, which means that all the remaining data will be erased, so the recover process becomes very complicated or even impossible. In any doubtful situations, take the hard disks out of the storage device as soon as possible and start the recover process. And that is all for now. Hopefully this video was useful.
