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 regular data integrity checks help prevent data loss in NAS Synology ioSafe 220+ devices?

Yes, regular data integrity checks can help prevent data loss in NAS Synology ioSafe 220+ devices. Data integrity checks involve verifying the consistency and accuracy of data stored on the device. By regularly performing these checks, you can identify and correct any potential data corruption or errors before they lead to data loss.

Synology NAS devices offer various data integrity features, such as data scrubbing and RAID (Redundant Array of Independent Disks) technologies, which can help detect and repair data inconsistencies. Data scrubbing involves periodically scanning the data stored on the NAS to identify and repair any errors or inconsistencies. RAID configurations, such as RAID 1 (mirroring), provide redundancy by storing data on multiple drives, allowing for data recovery in case of drive failures.

Regularly scheduling and performing data integrity checks, along with utilizing RAID and other built-in features, can significantly reduce the risk of data loss on NAS Synology ioSafe 220+ devices. Additionally, it's crucial to maintain proper backup strategies to ensure data protection in case of catastrophic events or multiple drive failures.

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

Although NAS ioSafe 220+ 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.

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.

Where are user’s files stored?

The Synology ioSafe 220+ 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.

  • How does a NAS Synology ioSafe 220+ provide better accessibility and convenience compared to traditional external hard drives?

    The NAS Synology ioSafe 220+ provides better accessibility and convenience compared to traditional external hard drives in several ways:

    1. Network Accessibility: The ioSafe 220+ is a Network Attached Storage (NAS) device, which means it connects directly to your network router. This allows multiple devices on the same network to access and share files simultaneously. In contrast, traditional external hard drives typically connect to a single computer via USB, limiting accessibility to that specific device.
    2. Remote Access: With the ioSafe 220+, you can access your files remotely from anywhere with an internet connection. This is particularly useful for accessing files when you are away from home or the office. Traditional external hard drives require physical connection to the computer they are connected to, making remote access impossible.
    3. Centralized Storage: The ioSafe 220+ acts as a centralized storage solution for all your devices. You can store and access files from various devices such as computers, smartphones, and tablets, without the need to transfer files between devices or carry the external hard drive with you. Traditional external hard drives require physically connecting and disconnecting them from different devices to access files.
    4. Data Redundancy and Protection: The ioSafe 220+ offers data redundancy and protection features such as RAID (Redundant Array of Independent Disks) configurations, which can help protect your data from drive failures. It also supports automatic backups and synchronization, ensuring your data is safely stored and protected. Traditional external hard drives do not typically offer these built-in data protection features.
    5. Expandable Storage: The ioSafe 220+ allows for easy expansion of storage capacity by adding additional hard drives to its available drive bays. This enables you to increase storage space without having to purchase a new device. Traditional external hard drives have fixed storage capacities and require purchasing additional drives if more space is needed.

    Overall, the NAS Synology ioSafe 220+ provides better accessibility and convenience by offering network accessibility, remote access, centralized storage, data redundancy and protection, and expandable storage options compared to traditional external hard drives.
