Select the ones you need to restore and do it.RAID configurations are secure, fast, and convenient ways to store valuable data. As a result, you can see the files which are still on the disks. Right-click on the RAID and run Fast Scan. The program was able to rebuild the RAID even though two disks are missing. So if your computer doesn’t have enough ports to connect all disks, you can easily exclude two of them from the array. In RAID-Z2, you are required to use at least four disks. It is similar to RAID 6 and it can survive even if two disks are down. RAID-Z2 is more failure-resistant as it uses two parity blocks and two data blocks for every single bunch of data.

In order to recover any information, from RAID-z2 (that is, a second-level array) you also need to connect its disks to a Windows computer and then run Hetman RAID Recovery.
#Raid data recovery how to
How to recover data from a RAIDz2 system (second level) When the recovery process is over, you’ll find all of the files in the folder you have chosen. We don’t recommend saving them to the same disk, so make sure you have another storage device to put your recovered data to. As the final step, select the ones you need and click “Recovery” don’t forget to select where exactly the files have to be saved. If your motherboard doesn’t have enough ports to connect all the drives, there are all kinds of various adapters and expansion cards to fix this problem.Īs you can see, the program managed to find all the files that have been removed from the disk.
This program supports most popular file systems and RAID types.įor recovery, take the disks out of the server and connect them to a Windows computer. This is a comprehensive solution for NAS data recovery to help you restore your files in a number of different scenarios. This program can automatically rebuild a RAID system created with the help of that file system. Hetman RAID Recovery supports the ZFS file system and RAID-z arrays of all levels. But as I said before, only a few data recovery tools can handle this specific RAID type. RAID-Z1 is very similar to RAID 5, as it uses single-parity data storage pattern, and it is designed to survive losing one of the disks in its array. In this case, data is distributed across the array in the most optimal way. RAID-Z1 makes sure that every unique block of data is written, so that recovery is possible if any of the drives suffers a failure or breakdown. Now let’s explore how to recover some information that was removed accidentally from a RAID-z array. How to Recover Data from a RAID-z Array, ZFS File System, and a NAS with TrueNAS Core Here, click the buttons “Add” and then “Create Pool”. Start by accessing the TrueNAS management menu and expanding the tab “Storage” – “Pools”. Now let’s find out how to build RAID-z2 (that is, an array of the second level).
#Raid data recovery install
In one of our videos, you can see how to install and configure such operating system and how to create a RAID-z. However, Hetman RAID Recovery can analyze its metadata to identify the proper structure of RAID-z and then rebuilds the damaged RAID on the fly, and does it automatically. ZFS was developed with reliability in mind, which is achieved by using various features such as copy-on-write, redundant metadata, journaling and others.īecause of the complicated structure of this file system, conventional data recovery tools are useless when it comes to restoring information from RAID-z arrays. Due to the dynamic nature of this file system, its data can only be recovered if the metadata is not damaged. The information about the size of each stripe is written to metadata. It uses dynamic striping instead of fixed-width stripes.
The data distribution mechanism in RAID-z is similar to the conventional RAID 5, but with slight differences.
