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 malware or ransomware attacks lead to data loss in NAS QNAP TVS-1282 devices?

Yes, malware or ransomware attacks can potentially lead to data loss in NAS QNAP TVS-1282 devices. NAS devices are not immune to such attacks, and if a device is infected with malware or targeted by ransomware, it can result in the encryption, deletion, or corruption of data stored on the device. It is important to take necessary security measures, such as regularly updating firmware, using strong passwords, implementing firewalls, and regularly backing up data, to minimize the risk of data loss.

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

Although NAS TVS-1282 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 (Internet Small Computer System Interface) is a protocol that allows the transmission of SCSI (Small Computer System Interface) commands and data over IP networks. It enables the remote use of storage devices over a network, typically Ethernet.

    Here's how iSCSI works:

    1. Initiator: The device that initiates the communication and sends SCSI commands is called the initiator. It can be a server, workstation, or any device that needs to access storage.
    2. Target: The device that provides the storage resources and responds to the SCSI commands is called the target. It can be a storage array, disk drive, or any device that offers storage.
    3. TCP/IP Network: iSCSI uses TCP/IP as the underlying network protocol. It allows the initiator and target to communicate with each other over an IP network, such as a LAN or the internet.
    4. iSCSI Protocol: The iSCSI protocol encapsulates SCSI commands and data into TCP/IP packets. It allows the initiator to send SCSI commands to the target and receive responses. These commands include reading, writing, and other storage-related operations.
    5. Initiator-Target Connection: The initiator establishes a connection with the target over the IP network. This connection is known as an iSCSI session. It can be a direct connection or routed through switches and routers.
    6. Logical Unit Number (LUN): The target presents its storage resources as Logical Unit Numbers (LUNs). Each LUN represents a specific storage volume or device that the initiator can access. The initiator identifies the LUN it wants to access within the iSCSI session.
    7. SCSI Commands and Data: The initiator sends SCSI commands to the target, such as read or write requests. These commands are encapsulated into iSCSI packets and transmitted over the IP network. The target processes the commands and responds accordingly.
    8. Data Transfer: When data needs to be transferred, the initiator sends the data to the target, which stores it on the specified LUN. Similarly, the target can send data back to the initiator in response to read requests.
    9. SCSI Responses: The target responds to the initiator's SCSI commands with status information, data, or error messages. The initiator interprets these responses and takes appropriate actions.

    Overall, iSCSI allows for the remote access and utilization of storage devices by leveraging existing IP networks. It enables cost-effective storage solutions, centralizes storage management, and provides flexibility in storage provisioning and allocation.

  • What are the advantages and benefits of using iSCSI in a network storage environment?

    4. Performance: While iSCSI is not as fast as FC, it offers sufficient performance for most applications. With advancements in network speeds and technologies, iSCSI performance has improved significantly over the years.
    5. Simplicity: iSCSI uses the existing IP network infrastructure, making it easier to set up and manage compared to FC. It simplifies storage management tasks and reduces the need for specialized storage networking skills.
    6. Compatibility: iSCSI is compatible with existing IP-based networks, allowing organizations to leverage their existing investments in networking equipment and expertise.
    7. Data protection: iSCSI supports various data protection mechanisms, such as encryption, authentication, and access control. This ensures 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 efficiently. It enables features like live migration, high availability, and centralized storage management.
    9. Disaster recovery: iSCSI enables remote replication of data, making it easier to implement disaster recovery solutions. Organizations can replicate data to remote locations for backup and quick recovery in case of a disaster.

    Overall, iSCSI provides a cost-effective, flexible, and scalable solution for network storage environments, offering performance and simplicity without the need for specialized hardware or expertise.
