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 TerraMaster 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 backup and recovery strategies help reduce potential data loss risks on NAS TerraMaster F2-221 devices?

Yes, the use of specific backup and recovery strategies can help reduce potential data loss risks on NAS TerraMaster F2-221 devices. Here are some strategies that can be employed:

  1. Regular backups: Implement a regular backup schedule to create copies of important data stored on the NAS device. This can be done using built-in backup software or third-party backup solutions.
  2. Offsite backups: Store backup copies of data in a different physical location or on cloud storage services. This ensures that even if the NAS device is damaged or stolen, the data remains safe and accessible.
  3. RAID configuration: Configure the NAS device with a RAID (Redundant Array of Independent Disks) setup to provide data redundancy. RAID levels like RAID 1 or RAID 5 can help protect against disk failures by mirroring or striping data across multiple drives.
  4. Snapshot feature: Utilize the snapshot feature if available on the NAS device. Snapshots capture the state of the data at a specific point in time, allowing for easy recovery in case of accidental deletion or modification of files.
  5. Disaster recovery plan: Develop a comprehensive disaster recovery plan that outlines the steps to be taken in case of data loss or system failure. This plan should include procedures for restoring data from backups and getting the NAS device back up and running.
  6. Regular maintenance: Perform regular maintenance tasks such as firmware updates, disk health checks, and monitoring system logs for any signs of potential issues. This helps identify and address problems before they lead to data loss.

By implementing these backup and recovery strategies, the risk of data loss on NAS TerraMaster F2-221 devices can be significantly reduced.

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

Although NAS F2-221 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 TerraMaster F2-221. 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 TerraMaster

F2-221 has 2 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • Ext2;
  • Ext3;
  • Ext4;
  • Btrfs;

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 ToolsSave 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 TerraMaster F2-221 network-attached storage keeps OS Linux 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.

    Can deleted files be recovered from a NAS TerraMaster F2-221 device?
    • Hetman Software
      Hetman Software 10.09.2023 18:00 #

      It is possible to recover deleted files from a NAS TerraMaster F2-221 device, but it depends on various factors. When a file is deleted from a NAS device, it is typically moved to a recycle bin or trash folder within the NAS system. If the file is still present in the recycle bin, it can be easily restored.

      However, if the file has been permanently deleted or the recycle bin has been emptied, the chances of recovery decrease. In such cases, you may need to use specialized data recovery software or seek professional assistance to attempt file recovery.

      It's important to note that the success of file recovery also depends on factors like the file system used on the NAS device, the amount of time that has passed since the file was deleted, and whether the storage space has been overwritten with new data.

      To maximize the chances of recovering deleted files, it is recommended to immediately stop using the NAS device and avoid writing new data to it.
