Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Synology often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Can overheating or improper ventilation cause data loss on NAS Synology ioSafe 1019+ devices?

Yes, overheating or improper ventilation can potentially cause data loss on NAS Synology ioSafe 1019+ devices. Overheating can lead to component failures, including hard drives, which can result in data corruption or loss. Proper ventilation is crucial to ensure that the device operates within optimal temperature ranges and prevents overheating. It is recommended to place the NAS device in a well-ventilated area and follow the manufacturer's guidelines for temperature and airflow requirements to minimize the risk of data loss.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS ioSafe 1019+ can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

Step-by-Step Data Recovery with Hetman RAID Recovery

Hetman Raid Recovery

This program restores data from damaged RAID arrays and is fully compatible with Synology ioSafe 1019+. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually Stored?

The Synology ioSafe 1019+ 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.

  • What are the recommended backup and disaster recovery settings for the NAS Synology ioSafe 1019+ to safeguard important data and ensure business continuity in case of hardware failure or other emergencies?

    To safeguard important data and ensure business continuity in case of hardware failure or other emergencies, here are the recommended backup and disaster recovery settings for the NAS Synology ioSafe 1019+:

    1. RAID Configuration: Set up a RAID (Redundant Array of Independent Disks) for data redundancy. RAID 5 or RAID 6 is recommended for the ioSafe 1019+ as they provide fault tolerance by distributing data across multiple disks.
    2. Scheduled Backups: Configure regular backups of your critical data to an external storage device or another NAS. Synology DSM (DiskStation Manager) provides built-in backup tools like Hyper Backup or Snapshot Replication that can be scheduled to run automatically.
    3. Off-site Replication: Replicate your data to an off-site location to protect against physical disasters like fire, flood, or theft. Synology offers options like Synology C2 cloud backup or setting up a remote NAS at a different location.
    4. Versioning and Snapshotting: Enable versioning and snapshot features to keep multiple versions of files and folders. This allows you to roll back to a previous state in case of accidental deletion, corruption, or ransomware attacks.
    5. UPS Integration: Connect the ioSafe 1019+ to an Uninterruptible Power Supply (UPS) to protect against power outages. This ensures that the NAS has enough time to shut down properly, preventing data loss or corruption.
    6. High Availability (HA): If maximum uptime is critical, consider setting up High Availability with another Synology NAS. This allows for automatic failover in case of hardware failure, ensuring minimal downtime.
    7. System Monitoring and Notifications: Enable system monitoring and configure email or push notifications to receive alerts about any potential issues, such as disk failures, high temperatures, or network connectivity problems.
    8. Regular Testing and Verification: Periodically test your backup and disaster recovery processes to ensure they are working correctly. Verify that you can restore data from backups and access replicated data at the off-site location.
    9. Security Measures: Implement security measures like strong passwords, two-factor authentication (2FA), and firewall settings to protect against unauthorized access and potential data breaches.

    Remember to regularly review and update your backup and disaster recovery strategy as your business requirements evolve.
