Infortrend EonStor DS 1016 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from EonStor DS 1016.

How to recover data from NAS Infortrend EonStor DS 1016

Recover data from damaged RAID arrays inaccessible from a computer.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Infortrend also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can accidental deletion or user error cause data loss in NAS Infortrend EonStor DS 1016 devices?

Yes, accidental deletion or user error can cause data loss in NAS Infortrend EonStor DS 1016 devices. If a user accidentally deletes important files or folders, or if they mistakenly format the storage drives, it can result in the loss of data. It is always recommended to have proper backup systems in place and to exercise caution when performing operations on the NAS device to avoid such data loss incidents.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS EonStor DS 1016 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

      Yes, there are specific RAID configurations and levels used in NAS Infortrend EonStor DS 1016 devices that can affect data recovery. The EonStor DS 1016 supports various RAID levels, including RAID 0, RAID 1, RAID 3, RAID 5, RAID 6, RAID 10, RAID 30, RAID 50, and RAID 60.

      The choice of RAID level can impact data recovery in the following ways:

      1. RAID 0: This level offers striping without redundancy, meaning there is no data redundancy or fault tolerance. If one drive fails, all data is lost, and data recovery becomes extremely difficult or impossible.
      2. RAID 1: This level uses mirroring, where data is duplicated on two drives. If one drive fails, the other drive contains an exact copy of the data, allowing for easy data recovery.
      3. RAID 3, RAID 5, RAID 6: These levels use parity to provide fault tolerance. If a drive fails, data can be rebuilt using the parity information. However, if multiple drives fail or if there are issues during the rebuild process, data recovery can become more complex and may require professional assistance.
      4. RAID 10, RAID 30, RAID 50, RAID 60: These levels combine striping and mirroring or parity to offer both performance and fault tolerance. Data recovery can be relatively straightforward if a single drive fails, but multiple drive failures or other issues may complicate the recovery process.

      It is important to note that while RAID can provide some level of data protection, it is not a substitute for regular backups. In the event of a catastrophic failure or multiple drive failures, professional data recovery services may be required to recover the data from the NAS device.

  • Can you explain the specific RAID levels supported by the Infortrend EonStor DS 1016 and how they contribute to data protection and performance?

    The Infortrend EonStor DS 1016 supports several RAID levels, each offering different levels of data protection and performance. Here are the specific RAID levels supported by the EonStor DS 1016 and their contributions:

    1. RAID 0 (Striping): This level stripes data across multiple drives without any redundancy. It enhances performance by distributing data across multiple drives, but it does not provide any data protection. If one drive fails, all data on the array is lost.
    2. RAID 1 (Mirroring): RAID 1 duplicates data across two drives, providing full data redundancy. It offers excellent data protection as each drive contains a complete copy of the data. However, it does not enhance performance as data is written to both drives simultaneously.
    3. RAID 5 (Striping with Parity): RAID 5 stripes data across multiple drives and includes parity information for fault tolerance. It offers a good balance between performance and data protection. If a single drive fails, the lost data can be reconstructed using the parity information.
    4. RAID 6 (Striping with Dual Parity): RAID 6 is similar to RAID 5 but includes two sets of parity information. It provides higher data protection than RAID 5 as it can tolerate the failure of two drives simultaneously. However, it requires more drives and has slightly lower write performance due to the additional parity calculations.
    5. RAID 10 (Mirrored Stripes): RAID 10 combines mirroring (RAID 1) and striping (RAID 0). It requires a minimum of four drives and offers both high performance and data protection. Data is striped across mirrored pairs of drives, providing redundancy and improved read/write performance.

    The choice of RAID level depends on the specific requirements of the application. RAID 0 is suitable for applications where performance is critical but data protection is not a concern. RAID 1, RAID 5, RAID 6, and RAID 10 offer varying degrees of data protection, with RAID 10 providing the highest level of both performance and data redundancy.
