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 snapshot or versioning features on NAS Promise UltraTrak SX4000 devices aid in data recovery after data loss?

Yes, the use of snapshot or versioning features on NAS Promise UltraTrak SX4000 devices can aid in data recovery after data loss. These features allow users to take periodic snapshots or create versions of their data, which can be used to restore files or folders to a previous state in the event of accidental deletion, corruption, or other data loss incidents.

By enabling snapshot or versioning features, users can create a backup of their data at different points in time. If data loss occurs, they can easily roll back to a previous snapshot or version to retrieve the lost or corrupted files. This can be particularly useful in situations where data loss is detected after a significant amount of time has passed since the last backup.

However, it is important to note that snapshot or versioning features are not a substitute for regular backups. While they can help recover data in certain scenarios, they may not be able to protect against hardware failures, catastrophic events, or other types of data loss. It is always recommended to have a comprehensive backup strategy in place, combining snapshot/versioning features with regular backups to ensure maximum data protection and recovery options.

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

Although NAS UltraTrak SX4000 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.

  • RAID 1E;
  • RAID 3;
  • RAID 5;
  • RAID 6;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

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 UltraTrak SX4000 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.

Questions and answers

  • What is iSCSI and how does it work in the context of network storage?

    iSCSI, or Internet Small Computer System Interface, is a protocol that allows the transmission of SCSI commands and data over IP networks. It enables the connection of storage devices, such as disk arrays or tape libraries, to servers over a network.

    In the context of network storage, iSCSI works by encapsulating SCSI commands and data into IP packets. These packets are then transmitted over a TCP/IP network, typically using Ethernet. The iSCSI protocol allows for the creation of virtual SCSI devices, known as iSCSI targets, on the storage device. These targets can be accessed by servers, known as iSCSI initiators, as if they were locally attached storage.

    When a server wants to access data on an iSCSI target, it initiates a connection to the target using the iSCSI protocol. This connection is established by exchanging a series of messages between the initiator and the target. Once the connection is established, the server can send SCSI commands to the target, such as read or write requests, to perform storage operations.

    The iSCSI protocol ensures reliable and secure data transmission by using TCP/IP for transport and incorporating features like error detection and correction, flow control, and authentication. It allows for the utilization of existing IP networks, eliminating the need for dedicated storage networks and reducing costs.

    Overall, iSCSI provides a flexible and cost-effective solution for network storage, allowing servers to access and utilize storage resources over a network connection.
