What Is NAS ?

NAS is also called network-attached storage, which is a file-level computer data storage server. NAS fixes unstructured data, such as audio, video, websites, text files, and Microsoft Office documents. There are three categories: Enterprise NAS, Midmarket NAS, and Desktop NAS.

We have mentioned NAS looks like a computer server but typically does not have a keyboard or display and is configured and managed with a browser-based utility. Contain a processor and a stripped-down operating system. Each NAS recovery resides on the local area network as an independent network node, defined by its own unique IP address.

What Is NAS Backup?

NAS Backup is to store drives via a network and can be treated as a form of data backup. The NAS backup system and NAS device support NAS Backup. We all know NAS can be a device to back up the data. Actually, it is vulnerable to threats, including flood, fire, device failure, and physical damage. 

It enables a substantial number of users and heterogeneous client devices to retrieve data from a centralized disk capacity. Users on a local area network access shared storage through a standard Ethernet connection. That means they can share data remotely.

What Is NAS Backup Used for?

The most salient advantage of NAS backup is that it ensures your data is protected so that you can recover NAS data in case of disaster. Therefore, it is widely used in home and business scenarios. 

For home users:

  • Create, test, and develop a personal website.
  • Store and serve multimedia files and automate backups
  • Manage security systems, torrent files, and smart-TV storage

For enterprise:

  • Archive information and recovery data from disaster 
  • Host server-based, open-source applications
  • Testing and developing web-based and server-side web applications
  • Save email and database

Pros and Cons of NAS Backup

After learning about what is NAS and NAS Backup, we will outline the advantages for you to have full use. Besides that, the disadvantages should be taken into value during the process of operation.


  • Lots of Users can access the drive at the same time
  • Users and devices can share files together
  • Remote access via Ethernet is possible
  • Provide additional functionality independent of the computer
  • Additional storage can be added 
  • Lower maintenance cost: the power of NAS devices is usually 10 to 20 watts
  • High transmission speed


  • Compared with DAS, the file transfer speed is low
  •  Basic network knowledge is needed
  •  Available function depends greatly on the chip and firmware

Although, NAS Backup stands outs for its ease of access, high capacity, and low cost. We can't ignore the disadvantages. If too many users overwhelm the system with requests simultaneously, Input/output will be affected. It would be best if you avoided the risk of preventing inevitable losses.
