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 Synology 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 data compression or deduplication techniques impact the performance and data integrity on NAS Synology ioSafe 218 devices?

The use of specific data compression or deduplication techniques can indeed impact the performance and data integrity on NAS Synology ioSafe 218 devices.

Data compression techniques aim to reduce the size of data by encoding it in a more efficient manner. While this can save storage space, it may also require additional processing power and time to compress and decompress the data. Consequently, the performance of the NAS device may be affected, especially during read and write operations.

Deduplication techniques identify and eliminate duplicate data blocks, thus reducing storage requirements. However, deduplication also requires additional processing power and memory to identify and manage the duplicate data. This can impact the overall performance of the NAS device, particularly during deduplication processes.

Furthermore, data integrity can be affected if the compression or deduplication processes are not implemented correctly. If there are any issues or errors during compression or deduplication, it may result in data corruption or loss. Therefore, it is crucial to ensure that the chosen compression or deduplication techniques are properly implemented and regularly tested for data integrity.

In summary, while data compression and deduplication techniques can provide storage efficiency benefits, they can also impact performance and data integrity on NAS Synology ioSafe 218 devices. It is important to carefully evaluate and monitor the impact of these techniques to ensure optimal performance and data reliability.

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

Although NAS ioSafe 218 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 Synology ioSafe 218. 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 Synology

ioSafe 218 has 2 HDD slots, and it supports the following array types:

  • Synology Hybrid RAID(SHR);
  • RAID 1;
  • RAID 0;
  • Basic;
  • JBOD;

NAS supports:

  • EXT4;
  • EXT3 (External Disk Only);
  • FAT32 (External Disk Only);
  • exFAT (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk 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 Synology ioSafe 218 network-attached storage keeps DSM (DiskStation Manager) 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.
