Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Idis often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Can the use of multiple NAS Idis DR-2116P devices in a backup or replication configuration mitigate data loss risks?

Yes, the use of multiple NAS Idis DR-2116P devices in a backup or replication configuration can help mitigate data loss risks.

By setting up multiple devices in a backup or replication configuration, you create redundancy in your data storage system. This means that if one device fails or experiences data loss, you can still retrieve your data from the other devices.

Additionally, using multiple devices allows for distributed data storage, which can enhance data protection. You can store copies of your data on different devices, ensuring that even if one device is compromised, the data remains safe on the others.

Furthermore, NAS devices often provide features like RAID (Redundant Array of Independent Disks) that can help protect against data loss. RAID configurations distribute data across multiple disks, providing redundancy and increasing the overall reliability of the storage system.

However, it's important to note that while using multiple NAS devices in a backup or replication configuration can mitigate data loss risks, it does not completely eliminate the possibility of data loss. Other factors such as hardware failures, natural disasters, or human errors can still pose risks to your data. Therefore, it's crucial to have a comprehensive backup strategy that includes offsite backups, regular data verification, and other best practices to ensure data protection.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS DR-2116P can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

  • What are the security implications of different file access levels on the NAS Idis DR-2116P?

    The NAS Idis DR-2116P has different file access levels that can impact the security of the system. Here are some security implications associated with these levels:

    1. Administrator Access: Administrators have full control over the NAS system, including the ability to modify settings, create or delete user accounts, and access all files and folders. It is crucial to ensure that only trusted individuals have administrator access as they can potentially compromise the entire system if their credentials are compromised.
    2. User Access: Users typically have limited access to specific files and folders based on their assigned permissions. However, if a user's account is compromised, an attacker may gain access to the files and folders associated with that user. Therefore, it is important to regularly review and update user permissions to minimize the risk of unauthorized access.
    3. Guest Access: Some NAS systems offer a guest access option, allowing users to access specific files or folders without requiring authentication. While this can be convenient for sharing files, it also poses a security risk as anyone with knowledge of the guest access URL or credentials can potentially access sensitive data. It is advisable to disable guest access or restrict it to only non-sensitive data.
    4. Public Folder Access: NAS systems often have a public folder where users can store and share files. The security implications of public folder access depend on the sensitivity of the data stored within it. If sensitive information is stored in the public folder, it is recommended to restrict access to authorized users or consider encrypting the files to protect them from unauthorized access.
    5. Remote Access: NAS systems may provide remote access capabilities, allowing users to access files and folders from outside the local network. Enabling remote access introduces additional security considerations, such as ensuring secure communication protocols (e.g., SSL/TLS), using strong authentication methods, and regularly updating the NAS firmware to address any security vulnerabilities.

    Overall, it is essential to carefully configure and manage file access levels on the NAS Idis DR-2116P to ensure that only authorized users have appropriate access to files and folders, minimizing the risk of unauthorized access or data breaches.
