How to recover data from QNAP TVS-EC880 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 QNAP TVS-EC880

QNAP TVS-EC880 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from TVS-EC880.

How to recover data from NAS QNAP TVS-EC880

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 QNAP also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Are there any guidelines for configuring security settings on NAS QNAP TVS-EC880 devices to prevent unauthorized access and potential data loss?

Yes, there are several guidelines you can follow to configure security settings on a QNAP TVS-EC880 NAS device to prevent unauthorized access and potential data loss. Here are some best practices:

  1. Change the default administrator password: Upon initial setup, change the default password for the administrator account to a strong, unique password.
  2. Enable two-factor authentication (2FA): QNAP NAS devices support 2FA, which adds an extra layer of security. Enable this feature and use an authentication app like Google Authenticator for enhanced protection.
  3. Regularly update firmware: Keep the NAS firmware up to date with the latest security patches and bug fixes. Check for updates regularly and apply them promptly.
  4. Disable unnecessary services: Disable any services or features that are not required for your specific use case. This reduces the attack surface and minimizes potential vulnerabilities.
  5. Use strong user passwords: Enforce strong passwords for all user accounts, and encourage users to regularly update their passwords. Avoid using common or easily guessable passwords.
  6. Limit access privileges: Assign appropriate access privileges to users and groups based on their roles and responsibilities. Grant only the necessary permissions to prevent unauthorized access and accidental data loss.
  7. Enable network access restrictions: Utilize firewall rules or access control lists (ACLs) to restrict access to the NAS from specific IP addresses or networks. This helps prevent unauthorized access attempts from external sources.
  8. Regularly backup data: Implement a backup strategy to regularly backup critical data stored on the NAS. Store backups on separate storage devices or off-site to protect against data loss due to hardware failure, theft, or disasters.
  9. Enable network encryption: Utilize protocols like SSL/TLS to enable encrypted communication between the NAS and client devices. This protects data during transmission and prevents eavesdropping or tampering.
  10. Monitor and log activities: Enable logging and monitoring features on the NAS to track and analyze user activities, system events, and potential security incidents. Regularly review logs for any suspicious activities or anomalies.

Remember, security is an ongoing process, and it's important to stay updated with the latest security practices and recommendations provided by QNAP.

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

Although NAS TVS-EC880 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.

  • ZFS;
  • EXT4;
  • EXT3;
  • exFAT;
  • FAT32 (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk Read Only);

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 QNAP TVS-EC880 network-attached storage keeps QTS (QuTS hero) 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.

    Can data recovery from a NAS QNAP TVS-EC880 device be performed if there are issues with the network interface card or port?
    • Hetman Software

      Yes, data recovery from a NAS QNAP TVS-EC880 device can still be performed even if there are issues with the network interface card or port.

      QNAP NAS devices typically have multiple ways to access the data stored on them, including through the network interface, USB ports, or direct connection to a computer using SATA cables. If the network interface card or port is not functioning properly, you can still recover the data by using alternative methods.

      One option is to connect the NAS directly to a computer using SATA cables. This allows you to bypass the network interface and access the data directly from the hard drives inside the NAS. You can then use data recovery software or services to recover the data.

      Another option is to remove the hard drives from the QNAP NAS and connect them to a different computer or NAS device to access the data. This can be done by connecting the drives internally using SATA cables or by using an external hard drive docking station or enclosure.

      If you're not comfortable performing these steps yourself, it's recommended to seek professional data recovery services who specialize in NAS devices. They will have the expertise and tools to recover data from a QNAP NAS even if there are issues with the network interface card or port.
