What Is NAS Backup?

NAS stands for Network Attached Storage. NAS is a storage system that can let computers access storage over a local area network. NAS is commonly used for sensitive data storage, and it is important to set up a backup for your NAS device to ensure you can recover data in case of data loss. 

NAS Backup is to store drives through a network and can be regarded as a form of data backup. A NAS backup is a method for backing up NAS data to another system or device. NAS backup shall also address all the additional aspects, such as the number of copies, retention periods and terms, different locations and platforms, and more. 

Though NAS is a very secure data storage device, we also need to back up data on it to avoid unexpected data loss.

Two Free Ways to Create NAS Backups

  1. Solution 1. Backing up NAS Devices with Cloud Drive
  2. Solution 2. Create NAS Backups to the Directly Attached USB Hard Disk

Here are two ways you can use to back up a NAS and protect the business or individuals from data loss and service disruption. I will share with you how to backup NAS.

Solution 1. Backing up NAS Devices with Cloud Drive

Backing up NAS to a cloud drive is also a feasible way. Cloud backup software has come under the spotlight for years, but few people use it. 

If you have backups in the cloud, your data is protected against disasters that may occur in your physical data center. With cloud drive, backups are created automatically, and, in addition, every backup is synced. Moreover, your files are backed up and stored in the cloud, and you can access your files wherever you are.

Google Drive, OneDrive, and Dropbox are all available to back up files on your computer. However, the mentioned three cloud backup tools are mainly for file backups and have limited control over backups.

I will show you how to back up files to NAS with OneDrive as an example. OneDrive offers 5 GB of free storage, giving you a place to store, share, and sync your files.

Guide: How to Back up NAS to OneDrive

Detailed steps are listed below, and therefore you can follow the guide to create backups.

Step 1. Type OneDrive in the search box on the taskbar.


Step 2. Sign in to your account, and if you don't have a OneDrive account, you can create one.


Step 3. Your OneDrive is ready for use after you finish all the guides.


Solution 2. Create NAS Backups to the Directly Attached USB Hard Disk

Some NAS devices provide ports that allow you to connect an external hard drive via USB protocols. A simple and easy backup method is to connect a hard drive to your NAS device and duplicate the files you want to protect.

However, this method is not automated. It requires physically attaching the disk, starting the copy operation, and ensuring it completes successfully. In addition, backups can be inconsistent if the to-be-backed-up files are opened or modified by applications while being copied.

Guide: How to Copy NAS to External USB Hard Drive

Step 3. Select the data or files you want to back up manually.

1. What are NAS and SAN? 

Both SAN and NAS are methods of managing storage centrally and sharing that storage with multiple hosts/servers. The difference is that NAS is Ethernet-based, while SAN can use Ethernet and Fibre Channel.

2. Can my NAS be hacked? 

Undoubtedly, NAS devices also have the potential to pose a security risk. By connecting your hard drives to a network, there is a possibility of providing access to hackers. Attacks against NAS are common in the business sector, and although attacks against private individuals are less profitable, they still happen.

3. How does NAS storage work? 

NAS is a dedicated file storage system that enables multiple users and heterogeneous client devices to retrieve data from a centralized disk capacity. Users on a local area network can access the shared storage via a standard Ethernet connection.

4. Can a NAS be a backup?

NAS cannot be the only backup solution both at work and in life. NAS devices are used as storage devices, but some businesses use them as backup solutions. NAS devices should not be the only backup way. This is because NAS devices are vulnerable to threats, such as device failure and physical damage.
