How to recover data from Promise G1100 NAS Gateway 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 Promise G1100 NAS Gateway

Promise G1100 NAS Gateway NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from G1100 NAS Gateway.

How to recover data from NAS Promise G1100 NAS Gateway

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

How can user authentication methods impact data loss risks for NAS Promise G1100 NAS Gateway devices?

User authentication methods can greatly impact data loss risks for NAS Promise G1100 NAS Gateway devices. Here are a few ways:

  1. Strong Password Policies: Implementing strong password policies, such as requiring complex passwords and regular password changes, can significantly reduce the risk of unauthorized access to the device. Weak or easily guessable passwords can make it easier for attackers to gain access and potentially cause data loss.
  2. Two-Factor Authentication (2FA): Enabling 2FA adds an extra layer of security by requiring users to provide an additional authentication factor, such as a code from a mobile app or a fingerprint scan, in addition to their password. This significantly reduces the risk of unauthorized access even if the password is compromised.
  3. Role-Based Access Control (RBAC): Implementing RBAC allows administrators to assign specific roles and permissions to different users or groups. This ensures that users only have access to the data and functions they need to perform their tasks, reducing the risk of accidental or intentional data loss.
  4. Account Lockouts and Intrusion Detection: Implementing account lockouts after a certain number of failed login attempts can help prevent brute-force attacks. Additionally, setting up intrusion detection and alert systems can notify administrators of any suspicious login attempts or unauthorized access attempts, allowing them to take immediate action to prevent data loss.
  5. Regular Security Updates: Keeping the NAS Gateway device's firmware and software up to date is crucial to address any security vulnerabilities. Regularly updating the device ensures that any known security issues are patched, reducing the risk of unauthorized access and potential data loss.

By implementing these user authentication methods, the overall security posture of the NAS Promise G1100 NAS Gateway devices can be significantly enhanced, reducing the risk of data loss.

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

Although NAS G1100 NAS Gateway 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.

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 Promise G1100 NAS Gateway 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.

    Are there any specific encryption methods used in NAS Promise G1100 NAS Gateway devices that may affect data recovery?
    • Hetman Software
      Hetman Software 8.09.2023 12:59 #

      The NAS Promise G1100 NAS Gateway device supports various encryption methods that can affect data recovery. One of the primary encryption methods used is AES (Advanced Encryption Standard), which is a symmetric encryption algorithm widely adopted for securing sensitive data. AES encryption can make data recovery difficult or even impossible without the encryption key.

      Additionally, the NAS Promise G1100 may support other encryption features such as SSL/TLS for secure communication and data transfer, and possibly even RAID configurations with encryption capabilities. These encryption methods can further enhance data security but may complicate data recovery in case of data loss or hardware failure.

      It's important to note that the specific encryption methods and settings can vary depending on the configuration and firmware version of the NAS Promise G1100 device. It is recommended to consult the product documentation or contact the manufacturer for detailed information on the encryption methods used and their impact on data recovery.
