How to recover data from Infortrend EonServ EVi 5016 NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Infortrend EonServ EVi 5016

Infortrend EonServ EVi 5016 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from EonServ EVi 5016.

How to recover data from NAS Infortrend EonServ EVi 5016

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 implementing user quotas or permissions help prevent accidental data loss on NAS Infortrend EonServ EVi 5016 devices?

Yes, implementing user quotas or permissions can help prevent accidental data loss on NAS Infortrend EonServ EVi 5016 devices. User quotas allow you to set limits on the amount of storage space each user can consume on the NAS device. By setting appropriate quotas, you can prevent users from inadvertently filling up the storage and causing data loss.

Additionally, setting permissions for different users or user groups can help control access to files and folders on the NAS device. By assigning specific permissions, you can ensure that only authorized users have read, write, or delete access to certain data. This helps prevent accidental deletion or modification of critical files, reducing the risk of data loss.

It is important to carefully plan and configure user quotas and permissions based on your organization's requirements and the sensitivity of the data stored on the NAS device. Regular monitoring and auditing of user activities can also help identify any potential issues or unauthorized access attempts.

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

Although NAS EonServ EVi 5016 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Infortrend EonServ EVi 5016. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The Infortrend EonServ EVi 5016 network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

      Yes, it is possible to recover data from a NAS Infortrend EonServ EVi 5016 device that has undergone a system update or software upgrade. However, it depends on the specific circumstances and the extent of the changes made during the update or upgrade process.

      If the update or upgrade process was performed correctly and did not involve any data loss or corruption, then the data on the NAS should remain intact and accessible after the process is completed. In this case, you should be able to access your data as usual.

      However, if the update or upgrade process resulted in data loss or corruption, data recovery may be required. In such cases, it is recommended to contact a professional data recovery service provider who specializes in NAS devices. They will have the expertise and tools to assess the situation, recover the data, and restore it to a usable state.

      It is important to note that attempting to recover data on your own or using inexperienced data recovery methods may further damage the data or make it more difficult to recover. Therefore, it is best to seek professional assistance in such situations.
