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 regular system monitoring and alerting help in early detection and prevention of data loss events on NAS QNAP Turbo Station TS-100 devices?

Regular system monitoring and alerting can help in early detection and prevention of data loss events on NAS QNAP Turbo Station TS-100 devices in the following ways:

1. Disk Health Monitoring: Monitoring the health of the hard drives in the NAS can help detect any issues such as bad sectors, high temperature, or imminent disk failures. Alerts can be set up to notify administrators about these issues, allowing them to take preventive actions like replacing the failing drives before any data loss occurs.
2. RAID Array Monitoring: If the NAS is configured with a RAID array, monitoring the status of the array can help detect any degraded or failed disks. Alerts can be configured to notify administrators so that they can replace the faulty disks and rebuild the array before any data loss occurs.
3. Storage Space Monitoring: Monitoring the storage space utilization on the NAS can help identify situations where the storage is running out of space. This can prevent data loss events that may occur due to lack of available storage. Alerts can be set up to notify administrators when the storage reaches a certain threshold, allowing them to take actions like adding more drives or optimizing the storage usage.
4. Network Monitoring: Monitoring the network connectivity and performance of the NAS can help detect any issues that may lead to data loss events. For example, if the NAS is experiencing frequent network disconnections or high latency, it may indicate a problem with the network infrastructure. Alerts can be configured to notify administrators so that they can investigate and resolve the network issues before any data loss occurs.
5. Backup Monitoring: If the NAS is used for backup purposes, monitoring the backup jobs and their status can help ensure that the backups are running successfully and without any errors. Alerts can be set up to notify administrators if any backup job fails or encounters issues, allowing them to take corrective actions and prevent data loss events.

Overall, regular system monitoring and alerting provide proactive measures to detect and prevent data loss events on NAS QNAP Turbo Station TS-100 devices, minimizing the risk of data loss and ensuring the availability and integrity of the stored data.

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

Although NAS Turbo Station TS-100 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.

   How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with QNAP Turbo Station TS-100. 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.

How to recover data from a QNAP

Turbo Station TS-100 has 1 HDD slots, and it supports the following array types:

• Q-RAID 1;

NAS supports:

• EXT4;
• EXT3;
• 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 Tools – Save 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.

   

4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

   

Where are user’s files stored?

The QNAP Turbo Station TS-100 network-attached storage keeps QTS 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.
