QNAP Turbo Station TS-432PXU / TS-432PXU-RP NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from Turbo Station TS-432PXU / TS-432PXU-RP.

How to recover data from NAS QNAP Turbo Station TS-432PXU / TS-432PXU-RP

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.

Can the use of multiple NAS QNAP Turbo Station TS-432PXU / TS-432PXU-RP devices in a backup or replication configuration mitigate data loss risks?

Yes, using multiple NAS QNAP Turbo Station TS-432PXU / TS-432PXU-RP devices in a backup or replication configuration can help mitigate data loss risks. Here's how:

  1. Redundancy: By having multiple NAS devices, you can create redundant copies of your data. If one NAS fails or experiences data loss, you can rely on the other NAS devices to recover the data.
  2. Replication: NAS devices like QNAP Turbo Station support data replication, allowing you to synchronize data between multiple NAS devices. This ensures that your data is consistently backed up across multiple devices.
  3. Off-site backup: You can place one of the NAS devices in a separate physical location, such as a different building or even a different city. This provides an additional layer of protection against data loss due to disasters like fire, theft, or natural calamities.
  4. RAID configurations: QNAP Turbo Station supports various RAID configurations, such as RAID 1, RAID 5, or RAID 6. These configurations offer data redundancy and can help recover data in case of drive failures.
  5. Snapshot and versioning: Some NAS devices offer snapshot and versioning features, allowing you to take point-in-time snapshots of your data or maintain multiple versions of files. This can be useful in recovering from accidental deletions or file corruptions.

By combining these features and utilizing multiple NAS devices, you can significantly reduce the risk of data loss and increase the availability and reliability of your backups.

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

Although NAS Turbo Station TS-432PXU / TS-432PXU-RP 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.

Questions and answers

  • What is iSCSI and how does it work?

    iSCSI stands for Internet Small Computer System Interface. It is a network protocol that allows the transmission of SCSI (Small Computer System Interface) commands over IP networks, enabling the connection of storage devices over a network.

    iSCSI works by encapsulating SCSI commands within IP packets, allowing them to be sent over Ethernet networks. It uses the TCP/IP protocol suite for reliable and secure data transmission. The iSCSI initiator, typically a server or a computer, sends SCSI commands to the iSCSI target, which is a storage device or a storage array.

    Here's a step-by-step overview of how iSCSI works:

    1. Initiator Discovery: The iSCSI initiator discovers available iSCSI targets on the network. This is typically done through a process called Service Location Protocol (SLP) or by manually configuring the initiator with the target's IP address.
    2. Login: The initiator establishes a connection with the target by sending a login request. This involves authentication and negotiation of parameters such as security settings, data transfer size, and error handling.
    3. Command Execution: Once the login is successful, the initiator can send SCSI commands to the target. These commands include read, write, and other storage-related operations.
    4. Data Transfer: The target processes the received SCSI commands and performs the requested operations on the storage devices. It then sends the requested data back to the initiator over the network.
    5. Logout: When the initiator no longer requires access to the target, it sends a logout request to terminate the connection.

    iSCSI offers advantages such as flexibility, scalability, and cost-effectiveness compared to traditional Fibre Channel (FC) storage networks. It allows organizations to leverage existing IP networks for storage connectivity, eliminating the need for separate dedicated storage networks.

  • What are the benefits of using iSCSI in a network storage environment?
    1. Cost-effective: iSCSI allows organizations to use existing Ethernet infrastructure, eliminating the need for specialized Fibre Channel equipment. This can significantly reduce the cost of implementing a network storage solution.
    2. Flexibility: iSCSI can be implemented over any standard Ethernet network, allowing organizations to leverage their existing network infrastructure. It can be easily integrated into both local area networks (LANs) and wide area networks (WANs), providing flexibility in terms of storage deployment.
    3. Scalability: iSCSI supports the use of multiple initiators (servers) connecting to multiple targets (storage devices). This enables organizations to scale their storage infrastructure as their needs grow, without significant additional investment.
    4. Performance: iSCSI leverages high-speed Ethernet networks, allowing for fast data transfer rates. With advancements in Ethernet technology, such as 10GbE and even 100GbE, iSCSI can provide high-performance storage solutions.
    5. Centralized management: iSCSI allows for centralized management of storage resources. Storage devices can be easily provisioned, managed, and monitored from a single management interface, simplifying storage administration.
    6. Compatibility: iSCSI is compatible with various operating systems, including Windows, Linux, and Unix. This ensures that organizations can integrate iSCSI into their existing infrastructure without compatibility issues.
    7. Data protection: iSCSI supports various data protection mechanisms, such as encryption and authentication, ensuring the security and integrity of data transferred over the network.
    8. Virtualization support: iSCSI is widely used in virtualized environments, as it allows virtual machines to access shared storage resources over the network. This enables features like live migration and high availability in virtualized environments.
    9. Disaster recovery: iSCSI can facilitate remote replication of data, allowing organizations to create off-site backups for disaster recovery purposes. This ensures that data can be quickly restored in the event of a disaster.

    Overall, the benefits of using iSCSI in a network storage environment include cost-effectiveness, flexibility, scalability, performance, centralized management, compatibility, data protection, virtualization support, and disaster recovery capabilities.
