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.

Are there any recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster?

Yes, there are several recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster:

  1. Regularly backup your data: Ensure that you have a regular backup schedule in place to ensure that your data is always up to date. Depending on your needs, this could be daily, weekly, or monthly backups.
  2. Use a reliable off-site backup location: Choose a secure and reliable off-site location to store your backups. This could be a cloud storage service, a data center, or a remote office in a different geographic location.
  3. Encrypt your backups: Encrypting your backups adds an extra layer of security, ensuring that even if your data is compromised, it cannot be accessed without the encryption key.
  4. Test your backups: Regularly test the restoration process to ensure that your backups are working properly. This will help you identify any issues or errors before a disaster occurs.
  5. Implement redundancy: Consider having multiple off-site backup locations to ensure redundancy. This way, if one location fails or is compromised, you still have another backup available.
  6. Automate the backup process: Use automated backup solutions to ensure that backups are performed consistently and without human error. This reduces the risk of forgetting to back up important data.
  7. Store backups offline: Consider storing backups offline, disconnected from your network, to protect against ransomware attacks or other cyber threats.
  8. Document your backup and recovery procedures: Maintain clear and up-to-date documentation of your backup and recovery procedures. This will help ensure that anyone involved in the process can follow the correct steps in case of a disaster.
  9. Regularly review and update your backup strategy: As your data and infrastructure evolve, regularly review and update your backup strategy to ensure it aligns with your current needs and technology advancements.

By following these recommended practices, you can minimize the risk of complete data loss and improve your chances of recovering your data in the event of a disaster.

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

Although NAS VS-8248 Pro+ 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with QNAP VS-8248 Pro+. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

VS-8248 Pro+ has 8 HDD slots, and it supports the following array types:

  • RAID 50;
  • RAID 60;
  • 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 VS-8248 Pro+ 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.
