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 data redundancy techniques such as mirroring or replication enhance data availability and protect against loss on NAS QNAP Turbo Station TS-1263XU-RP devices?

Data redundancy techniques such as mirroring or replication can enhance data availability and protect against loss on NAS QNAP Turbo Station TS-1263XU-RP devices in the following ways:

1. Mirroring: Mirroring, also known as RAID 1, involves creating an exact copy of data on multiple hard drives. In case one drive fails, the mirrored drive can take over seamlessly, ensuring uninterrupted access to data. QNAP Turbo Station TS-1263XU-RP supports various RAID levels, including RAID 1, for mirroring data.
2. Replication: Replication involves creating duplicate copies of data on separate NAS devices. This technique ensures that if one NAS device fails, the replicated data on the secondary device can be accessed immediately, minimizing downtime. QNAP Turbo Station TS-1263XU-RP supports various replication methods, such as RTRR (Real-Time Remote Replication), which allows continuous data synchronization between multiple NAS devices.
3. High Availability (HA) Cluster: QNAP Turbo Station TS-1263XU-RP supports HA clustering, which combines mirroring and replication techniques. In an HA cluster, two NAS devices operate in an active-passive mode, where one device serves as the primary (active) and the other as the secondary (passive). The primary NAS device handles data operations, while the secondary NAS device replicates data in real-time. If the primary device fails, the secondary device takes over seamlessly, ensuring uninterrupted data availability.
4. Snapshot and Snapshot Replica: QNAP Turbo Station TS-1263XU-RP supports snapshot technology, which captures the state of data at a specific point in time. Snapshots can be used for quick data recovery in case of accidental deletion or modification. Snapshot Replica allows replicating snapshots to another NAS device, providing an additional layer of protection against data loss.

Overall, these data redundancy techniques on QNAP Turbo Station TS-1263XU-RP devices enhance data availability by minimizing downtime and protecting against data loss due to hardware failures or disasters.

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

Although NAS Turbo Station TS-1263XU-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.

   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-1263XU-RP. 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-1263XU-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);

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-1263XU-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.
