🔶 Quick Overview: 

This article provides a comprehensive overview of Network Attached Storage (NAS) backups, emphasizing their critical role in data protection for both home and business users.

✔️ Key Takeaways:

  1. What is a NAS Backup: It is the process of creating extra copies of data from a central NAS device to protect against hardware failure, data corruption, ransomware, or accidental deletion.
  2. Why it's Necessary: A single NAS, even with redundancy (like RAID), is not a complete backup solution. The article advocates for the 3-2-1 backup rule: maintaining at least three copies of your data, on two different types of storage, with one copy stored off-site.
  3. Backup Strategies: The primary methods discussed are backing up a NAS to an external hard drive, to another NAS device (NAS to NAS), or to the cloud.

✔️ Recommended Software Tools:

What is a NAS Backup?

Data protection is essential in both home and business environments. When asking What is NAS backup, it refers to creating additional copies of data stored on a Network Attached Storage device. A NAS acts as a centralized hub where files from multiple devices are stored and accessed. A proper backup ensures that these files remain safe from hardware failure, corruption, or accidental deletion. Using a dedicated NAS backup drive adds another layer of protection. There are several NAS backup strategies, including backing up to an external hard drive, another NAS device, or to the cloud.

It is not only about storing files but about ensuring continuity, reliability, and long term data safety. A NAS is a dedicated file storage system with one or more drives that allows multiple users to collaborate and share data over a local network.

Why Do You Need to Make a NAS Backup?

Many users assume that a NAS device is already safe enough, especially if it uses a redundant array of independent disks configuration.

However, a single storage system is never enough. You still need to backup a NAS to protect against risks such as disk failure, system errors, ransomware, or unexpected events like fire or theft.

Backing up a NAS means creating a second copy of your data on another device. For robust data protection, it is recommended to follow the 3 2 1 backup rule. This rule advises having at least three copies of your data, on two different types of storage media, with at least one copy stored off site.

Even if your NAS is already used to store backups, having an additional copy follows best practices for data protection. Establishing automated NAS backup solutions ensures your files are always protected without requiring manual effort.

How to Execute a NAS to NAS Backup Effectively

A NAS to NAS backup is one of the most reliable strategies for maintaining full control over your data. This method involves copying files from one NAS device to another, which can be in the same local network or at a different location. It is especially useful for businesses or advanced users managing large amounts of data.

To implement this effectively, you should:

  • Choose a backup tool: Many NAS manufacturers like Synology and QNAP offer built-in tools such as Hyper Backup and Hybrid Backup Sync, respectively. Third-party software is also available. 
  • Configure the backup: You'll need to set up a connection between the two NAS devices, which usually involves entering the IP address and credentials of the destination NAS. 
  • Schedule the backup: For optimal protection, schedule automatic backups to run at regular intervals. You can choose between full, incremental, or differential backups. 
  • Enable extra features: Consider enabling features like data compression to save storage space and client-side encryption for added security. 

Once set up, the process runs seamlessly without interruption. This approach ensures your files are duplicated in real-time or at scheduled intervals, providing strong protection against local failures. For those using Synology, you can use Hyper Backup to back up Synology NAS to another Synology NAS. 

What Are The Best Software Tools?

Finding the right application to handle your network storage duplication is vital. The market offers several compelling options for those who want to nas back up their systems efficiently. Below are comprehensive reviews of the best choices available.
