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.

Can the use of specific backup and recovery strategies help reduce potential data loss risks on NAS QNAP TVS-675 devices?

Yes, the use of specific backup and recovery strategies can help reduce potential data loss risks on NAS QNAP TVS-675 devices. Here are some strategies that can be implemented:

  1. Regular backups: Implement a regular backup schedule to create copies of your important data. This can be done using QNAP's built-in backup tools or third-party backup software.
  2. Offsite backups: Store at least one copy of your backups offsite, preferably in a different physical location. This protects your data in case of disasters like fire, theft, or natural calamities.
  3. RAID configuration: Utilize RAID (Redundant Array of Independent Disks) configurations such as RAID 1, RAID 5, or RAID 6 to provide data redundancy and protection against drive failures. This ensures that your data remains accessible even if one or more drives fail.
  4. Snapshot technology: QNAP NAS devices often offer snapshot technology, which allows you to take point-in-time snapshots of your data. In case of accidental deletion or modification, these snapshots can be used to restore the data to a previous state.
  5. Cloud backups: Consider using cloud backup services to create additional copies of your data in secure remote servers. This provides an extra layer of protection against local hardware failures or disasters.
  6. Testing backups: It is essential to periodically test your backups to ensure they are working correctly and can be restored when needed. This helps identify any issues with the backup process and ensures the integrity of your data.

By implementing these backup and recovery strategies, you can significantly reduce the risks of data loss on your NAS QNAP TVS-675 device.

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

Although NAS TVS-675 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.

TVS-675 has 6 HDD slots, and it supports the following array types:

  • RAID 6;
  • RAID 5;
  • 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);

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-675 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.

      Yes, there are specific techniques used in data recovery from NAS QNAP TVS-675 devices with RAID configurations. Here are some common techniques:

      1. Rebuilding RAID: If the RAID array is degraded or one of the drives has failed, the first step is to rebuild the RAID array. This involves replacing the failed drive and allowing the system to rebuild the data onto the new drive.
      2. Data Reconstruction: In cases where multiple drives have failed or the RAID configuration is corrupted, data reconstruction techniques are employed. This may involve using specialized software or hardware tools to reconstruct the data from the remaining drives.
      3. Data Carving: Data carving is a technique used to recover specific files or data from a NAS device. It involves searching for file signatures or unique file structures to identify and extract specific files from the storage media.
      4. Forensic Analysis: In some cases, data recovery from a NAS device may require forensic analysis techniques. This involves examining the storage media at a low level to recover data that may have been deleted or overwritten.

      It is important to note that data recovery from NAS devices with RAID configurations can be complex and should be handled by experienced professionals. It is recommended to contact a reputable data recovery service provider who specializes in NAS devices for the best chances of successful recovery.
