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.

Can the use of multiple NAS Promise VTrak E830fD devices in a backup or replication configuration mitigate data loss risks?

Yes, the use of multiple NAS Promise VTrak E830fD devices in a backup or replication configuration can help mitigate data loss risks.

By implementing a backup or replication configuration with multiple devices, you create redundancy in your data storage infrastructure. This redundancy ensures that even if one device fails or experiences data loss, you still have copies of your data on other devices.

In a backup configuration, you can schedule regular backups of your data to multiple NAS devices. This ensures that if one device fails or data is lost, you can restore it from the backups stored on the other devices.

In a replication configuration, you can set up real-time or periodic replication of data between multiple NAS devices. This means that any changes or updates made to data on one device are automatically replicated to the others. If one device fails or experiences data loss, you can still access the replicated data on the other devices.

Overall, using multiple NAS Promise VTrak E830fD devices in a backup or replication configuration provides an additional layer of protection against data loss risks by creating redundancy and ensuring multiple copies of your data are available.

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

Although NAS VTrak E830fD 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Promise VTrak E830fD. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

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 VTrak E830fD 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.

  • Can the NAS Promise VTrak E830fD support multiple websites and handle heavy traffic efficiently?

    The NAS Promise VTrak E830fD is a storage solution and does not directly support hosting websites or handling heavy traffic. It can be used as a storage device for storing website files, but the actual hosting and traffic handling would typically be done by a separate server or hosting solution.

    To efficiently handle heavy traffic and multiple websites, you would need a robust server or hosting infrastructure with sufficient processing power, memory, and network bandwidth. Additionally, you may need to implement load balancing and caching mechanisms to distribute the traffic effectively and improve performance.

    It is important to consult with a professional or hosting provider to determine the appropriate infrastructure and setup for hosting multiple websites and handling heavy traffic efficiently.
