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.

Are there any recommended practices for regular testing and validation of data backups to prevent potential loss on NAS QNAP Turbo Station TS-1232XU-RP devices?

Yes, there are recommended practices for regular testing and validation of data backups on NAS QNAP Turbo Station TS-1232XU-RP devices to prevent potential data loss. Here are some best practices:

1. Regular Backup Schedule: Set up a regular backup schedule to ensure that backups are performed at regular intervals. This can be daily, weekly, or monthly, depending on the importance of the data.
2. Multiple Backup Copies: Maintain multiple copies of backups on different storage media or locations. This provides an additional layer of protection in case of hardware failure or disaster.
3. Offsite Backup: Store at least one copy of the backup offsite, preferably in a different physical location. This protects against fire, theft, or other disasters that could damage the primary backup.
4. Test Restores: Periodically test the restore process by restoring a subset of data from the backups. This helps ensure that the backups are valid and can be restored successfully when needed.
5. Verify Backup Integrity: Use built-in features or third-party tools to verify the integrity of backup files. This ensures that the backups are not corrupted and can be restored without issues.
6. Monitor Backup Status: Regularly check the backup status and logs to ensure that backups are running as scheduled and completing successfully. Address any errors or failures promptly.
7. Regularly Update Backup Software: Keep the backup software and firmware of the NAS device up to date to benefit from bug fixes, security patches, and new features.
8. Document Backup Procedures: Maintain documentation of the backup procedures, including the schedule, locations, and steps required to restore data. This helps ensure consistency and facilitates troubleshooting.
9. Perform Periodic Disaster Recovery Drills: Conduct periodic disaster recovery drills to simulate a complete data loss scenario and test the recovery process. This helps identify any gaps in the backup strategy and allows for improvements.
10. Regularly Review Backup Strategy: Review and update the backup strategy periodically to accommodate changing data needs, technology advancements, and business requirements.

By following these recommended practices, you can minimize the risk of data loss and ensure the reliability and effectiveness of your backups on QNAP Turbo Station TS-1232XU-RP devices.

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

Although the NAS Turbo Station TS-1232XU-RP 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-1232XU-RP. 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-1232XU-RP 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-1232XU-RP 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.
