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 Promise 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.

Are there any recommended practices for protecting NAS Promise Vess R2600xi PRO devices against physical theft or unauthorized access that can lead to data loss?

Yes, there are several recommended practices for protecting NAS Promise Vess R2600xi PRO devices against physical theft or unauthorized access that can lead to data loss. Here are some best practices:

1. Secure Physical Location: Place the NAS device in a secure and locked room or cabinet to prevent unauthorized physical access.
2. Restricted Access: Limit access to the NAS device to authorized personnel only. Implement strict access controls, such as strong passwords and multi-factor authentication, to prevent unauthorized login attempts.
3. Regular Firmware Updates: Keep the NAS device's firmware up to date with the latest security patches and updates provided by the manufacturer. This helps to protect against known vulnerabilities.
4. Network Segmentation: Place the NAS device on a separate network segment, isolated from the rest of the network. This prevents unauthorized users from gaining access to the NAS through other compromised devices on the network.
5. Encryption: Enable encryption on the NAS device to protect the data stored on it. This ensures that even if the device is stolen, the data cannot be accessed without the encryption key.
6. Backup and Disaster Recovery: Implement regular backups of the data stored on the NAS device to an off-site location or cloud storage. This helps to mitigate the risk of data loss in case of theft or physical damage to the device.
7. Monitoring and Logging: Enable logging and monitoring features on the NAS device to detect any suspicious activities or unauthorized access attempts. Regularly review the logs to identify any potential security issues.
8. Physical Security Measures: Implement additional physical security measures, such as surveillance cameras, motion sensors, and alarms, to deter theft and unauthorized access.
9. Employee Training: Educate employees about the importance of data security and the proper use of the NAS device. Train them on how to create strong passwords, recognize phishing attempts, and follow best practices for data protection.

By following these recommended practices, you can significantly reduce the risk of physical theft or unauthorized access leading to data loss on NAS Promise Vess R2600xi PRO devices.

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

Although the NAS Vess R2600xi PRO 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.

   How to Order Remote Data Recovery

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with Promise Vess R2600xi PRO. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

How to recover data from a Promise

Vess R2600xi PRO has 16 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 1E;
• RAID 3;
• RAID 5;
• RAID 6;
• RAID 30;
• RAID 50;
• RAID 60;
• JBOD;

NAS supports:

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

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

• Overwriting during the recovery process;
• Additional data loss caused by bad sectors;
• User errors.

To create a disk image, follow these steps:

1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

   

4. Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

   

Where Are the User’s Files Actually Stored?

The Promise Vess R2600xi PRO 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.
