TerraMaster F5-220 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from F5-220.

How to recover data from NAS TerraMaster F5-220

Recover data from damaged RAID arrays inaccessible from a computer.

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.

Are there any recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster?

Yes, there are several recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster. Here are some of them:

  1. Regularly backup your data: Create a backup schedule and ensure that your data is backed up frequently. This will minimize the risk of losing important information.
  2. Use multiple backup locations: Store your backups in multiple off-site locations to reduce the chances of losing data in case one location is affected by a disaster. This can include cloud storage, external hard drives, or off-site data centers.
  3. Encrypt your backups: Encrypting your backups adds an extra layer of security. In case your backups are compromised, encrypted data will be useless to unauthorized individuals.
  4. Test your backups: Periodically test the restoration process of your backups to ensure that the data can be successfully recovered. This will help identify any issues or errors in the backup process.
  5. Choose a reliable off-site storage provider: If you opt for cloud storage or off-site data centers, research and select a reliable and reputable provider. Ensure they have proper security measures in place to protect your data.
  6. Implement a disaster recovery plan: Develop a comprehensive disaster recovery plan that outlines the steps to be taken in the event of a disaster. This plan should include the process of retrieving and restoring data from off-site backups.
  7. Consider geographic separation: If possible, choose off-site backup locations that are geographically separated from your primary location. This reduces the risk of both locations being affected by the same disaster.
  8. Regularly review and update your backup strategy: Technology and business requirements change over time, so it's important to review and update your backup strategy regularly to ensure it remains effective.

By following these recommended practices, you can significantly reduce the risk of complete data loss in the event of a disaster.

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