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 QNAP 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.

How can user training or education help in minimizing data loss incidents on NAS QNAP Turbo Station TS-1263U devices?

User training or education can help in minimizing data loss incidents on NAS QNAP Turbo Station TS-1263U devices in the following ways:

1. Understanding data backup: Educating users about the importance of regular data backups and demonstrating how to set up and schedule backups on the QNAP Turbo Station can help prevent data loss incidents. Users should be trained on configuring backup jobs, selecting the appropriate backup destination, and verifying the backup process.
2. Security awareness: Users should be educated about the risks of data loss due to security breaches, such as malware attacks or unauthorized access. Training should cover topics like strong password practices, enabling two-factor authentication, and keeping the firmware and applications up to date to mitigate security vulnerabilities.
3. RAID configuration: Users should be trained on the different RAID configurations available on the QNAP Turbo Station and their impact on data redundancy and protection. Understanding RAID levels, such as RAID 1 or RAID 5, can help users choose the appropriate configuration to minimize the risk of data loss in case of drive failures.
4. File system management: Educating users on file system management best practices can help prevent accidental data loss. Users should be trained on proper file organization, avoiding unnecessary file deletions, and using features like file versioning or recycle bins to recover accidentally deleted files.
5. Disaster recovery planning: Users should be trained on disaster recovery planning, including creating and implementing a comprehensive plan for data recovery in case of catastrophic events like hardware failures, natural disasters, or ransomware attacks. Training should cover topics like off-site backups, data replication, and recovery procedures.
6. Regular maintenance and monitoring: Users should be educated about the importance of regular maintenance tasks like firmware updates, disk health monitoring, and regular system checks. Training should emphasize the significance of proactive monitoring and alert systems to identify potential issues before they lead to data loss incidents.

By providing comprehensive training and education to users, they can become more aware of the potential risks and take appropriate measures to prevent data loss incidents on NAS QNAP Turbo Station TS-1263U devices.

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

Although the NAS Turbo Station TS-1263U 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 QNAP Turbo Station TS-1263U. 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 QNAP

Turbo Station TS-1263U has 12 HDD slots, and it supports the following array types:

• RAID 50;
• RAID 60;
• RAID 5;
• RAID 6;
• RAID 10;
• RAID 0;
• RAID 1;
• JBOD;

NAS supports:

• ZFS;
• EXT4;
• EXT3;
• exFAT;
• FAT32 (External Disk Only);
• NTFS (External Disk Only);
• HFS+ (External Disk Read Only);

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 QNAP Turbo Station TS-1263U network-attached storage keeps QTS (QuTS hero) 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.
