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 QNAP also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can a NAS QNAP TVS-EC1280U-SAS-RP device's cache settings impact data loss risks?

The cache settings of a QNAP TVS-EC1280U-SAS-RP NAS device can impact data loss risks in the following ways:

  1. Write Cache: The device may have a write cache feature that temporarily stores data before writing it to the hard drives. While this can improve performance, it also introduces a risk of data loss in case of power loss or system failure before the data is written to the drives. If the cache is not properly synchronized with the drives, any data in the cache may be lost.
  2. Read Cache: The device may also have a read cache feature that stores frequently accessed data in a cache for faster retrieval. However, if the cache is not properly synchronized with the drives, there is a risk of data inconsistency or corruption if the cached data differs from the actual data on the drives.
  3. RAID Rebuild: In a NAS device with RAID configuration, if a hard drive fails and needs to be replaced, the device initiates a RAID rebuild process to restore data redundancy. During this process, the cache settings can impact the risk of data loss. If write caching is enabled, the rebuild process may rely on the cache to reconstruct data, and any data in the cache may be lost if there is a power loss or system failure.

To mitigate data loss risks, it is important to:

  • Ensure that the cache settings are properly configured and synchronized with the drives.
  • Use a reliable power source and consider implementing an Uninterruptible Power Supply (UPS) to prevent data loss due to power failures.
  • Regularly backup critical data to an external storage device or off-site location to have a secondary copy in case of any unforeseen data loss events.
  • Regularly monitor the health of the hard drives and RAID array for any signs of potential failure and take appropriate actions to prevent data loss.

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

Although NAS TVS-EC1280U-SAS-RP 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.

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 QNAP TVS-EC1280U-SAS-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.

Snapshots provide a fast and efficient way to recover data in case of accidental deletion, data corruption, or ransomware attacks. By taking regular snapshots, the NAS ensures that multiple versions of the data are available for recovery, enhancing data integrity and redundancy.
    4. Data Deduplication and Compression: The NAS employs data deduplication and compression techniques to optimize storage space and reduce backup times. Deduplication identifies and eliminates duplicate data, while compression reduces the size of the data being backed up. These technologies not only save storage space but also enhance data integrity by reducing the chances of storing corrupted or duplicate data.
    5. Network Redundancy: The NAS supports multiple network interfaces, including Ethernet and SAS, allowing for network redundancy. By connecting to multiple networks or switches, the NAS ensures that backup operations can continue even if one network connection fails. This redundancy enhances data integrity by preventing data loss due to network failures.
    6. Backup Software Integration: The NAS is compatible with various backup software solutions, including QNAP's own QNAP Hybrid Backup Sync. These software solutions provide advanced features such as incremental backups, versioning, and data verification, ensuring data integrity and redundancy during backup operations.

    Overall, the QNAP TVS-EC1280U-SAS-RP NAS combines hardware and software technologies to ensure data integrity and redundancy during backup operations, minimizing the risk of data loss and maximizing data availability.
