What is a File Server: Functions, Types, Pros, and Cons

Digital data plays a crucial role in our daily lives, as sharing and storing these files becomes more relevant in the digital age. One way to accomplish this is by using a file server. What most people don’t know is that File Servers are very important. Well, in this article, we will dig into the file server options that you may consider using and ideal for your storage needs.

What is a File Server?

A file server refers to the centralized location or storage in a computer network where files and information are kept and can be shared. It is in charge of the management and storing of data files. It is the main server that stores files or internal data media that is accessible to all authorized clients.

Exploring the Features of a File Server

File servers are usually used to enable multiple users to access the stored data and release storage space for the file repository. This reason made file servers popular, frequently used, and widely utilized by individual users.

Firms and businesses, especially those in the open-source industry, regularly use file servers as download servers linked to their web or online offerings. Users or visitors to their website can download specific content with ease, such as photos, videos, drivers, and software updates. They used FTP (File Transfer Protocol) and SFTP (Secure File Transfer Protocol) for accessing files.

It can also be used for backing up data, establishing protocols for authorization, blocking multiple users at the same time, also known as File Locking, as well as permission management.

How does File Server work?

The right hardware is a necessity for a reliable file server. A hard drive with enough capacity to hold space or files, operating system, and client software is also important so that it has enough processing power and sufficient working memory to enable quick access to data and programs for multiple users.

Special network protocols control the communication between the clients and the file server. The SMB (Server Message Block) is commonly used in local networks running Windows, MacOS, and PCs with Unix-like systems. However, clients and file servers running Unix/Linux must have software installed that implements the SMB protocols in order to integrate the two protocols into one network.

The file transfer protocol or its encrypted version, secure FTO, is typically supported by the Internet which is used to access the file. However, you can also use other options such as HTTP-based WebDAV protocols and SCP (secure copy).

Understanding the Functionality of a File Server

File servers make a remote or distant file system accessible. Any kind of data, such as images, videos, executables, and documents can be kept in the file server. It is responsible for managing and storing data files so that other computers that are connected to the same network can access them. This means it eliminates the need for users to physically transfer the files.

Different Types of File Servers

1. Dedicated File Server

These servers only offer support to other computers. This might take place in a specific local-area network that has an appropriately permitted access request linked to it. It is dedicated to one purpose as a file server which offers sufficient storage space for the website. It is also safer and more secure. The key characteristics and considerations of a dedicated file server are:

• Specialized Functionality
• Centralized Storage
• File Sharing
• Data Security
• Scalability
• Reliability and Redundancy
• Performance Optimization
• Management and Monitoring

2. Non-Dedicated File Server

It performs the same function as any other workstation. It can be utilized simultaneously as a workstation and also for routine activities. However, it offers less storage capacity for the website and is less secure and vulnerable to breaches and third-party hackers. The key characteristics and considerations of a non-dedicated file server are:

• Multi-Purpose Functionality
• Shared Resources
• Flexible Configuration
• Cost-Efficiency
• Trade-offs in Performance and Scalability
• Security Considerations
• Management Complexity

Exploring Standard Protocols Used in File Servers

SMB (Server Message Block)

This is a network file sharing protocol by Microsoft that is mainly used on printers, serial ports, and files within the server where it gives client nodes access. It is usually done by running DOS which can be IBM PC-DOS or Microsoft MS-DOS on an ethernet or LAN connection.

It also enables computer applications to write and read through files, as well as send service requests from server applications on a network. This can be utilized with the TCP/IP protocol as well as by similar network protocols. It can go through files and resources inside a server that is remote, and create, update, and read said files. What’s more interesting is that it uses the SMB Fabric Protocol through Storage Data and Storage Spaces Direct using its SDDC or Software-defined Data Center computing technologies.

NFS (Network File System)

Being designed by Sun Microsystems, this distributed file system protocol was to be used on a system that was adapted as time went on to other more common OS. It was called the UNIX operating system and it is supposed to be based on the open standard being policed by the Internet Engineering Task Force (IETF) which currently has upgraded to Version 4 from Version 3.

This was not designed to handle serial port functions that were shared like SMB, as those tasks were usually handled by the UNIX OS. NFS may be more efficient than SMB in sharing services, and for miniscule writes and reads.

FTP (File Transfer Protocol)

It is presumably the first option that comes to mind when it comes to business file transfers. It is a standard network protocol used for transmitting files between computers through a network. FTP is designed to send files in bulk, as well as individually. It is an essential tool for those who build and maintain websites and allows them to share electronic files without having to be in the same space. As always, it requires a working Internet connection.

With its decades-long existence, FTP played a crucial role in the evolution and development of computer networks. It offers a dependable and effective means of file transfer to both people and businesses as it can simplify the sharing process and save you time.

SFTP (SSH File Transfer Protocol)

SFTP is a secure file transfer protocol that operates over a Secure Shell (SSH) connection. It is perfect for requiring privacy or if you want a robust security capability because it offers powerful authentication encryption, and secure file access and transfer capabilities. SFTP is well-known for being easy to use and compatible with a wide range of software programs and operating systems.

It also uses a single encrypted channel for both control and data transfer which simplifies the setup and configuration process, making it easier to initiate secure file transfers. Furthermore, it supports a variety of authentication techniques, such as password-based public key, and keyboard-interactive authentication.

Its compatibility with a variety of operating systems and software programs makes it a flexible option for organizations or businesses requiring file transfers across diverse environments.

AFP (Apple Filing Protocol)

The Apple Filing Protocol is known as a network file control protocol system that was created by Apple and designed specifically for platforms on Mac. It was first known as “AppleTalk Filing Protocol”. AFP is frequently used for networks that operate fast wherein files with huge sizes need to be sent, including graphics, print, and video. This also includes spaces where Macs are used more commonly. It was designed so that it virtually needed no maintenance at all and has a very simple setup to the point where non-technical users can utilize this networking in Mac OS.

HTTP (Hypertext Transfer Protocol)

Just like FTP, HTTP file transfer is a popular protocol for business file transfers as it is easy to implement, particularly for person-to-server and person-to-person file transfers. Users just need a web browser, such as Chrome, Internet Explorer, Firefox, or Safari, and do not need to install anything to get started. However, HTTP is inherently unsafe and unable to safeguard data or comply with legal requirements. This may become a huge security risk where your files might be compromised, along with the important data inside it.

HTTPS (Hypertext Transfer Protocol Secure)

HTTPS is an extension of standard HTTP protocol as it is frequently used for secure online communication. It is mostly meant for web browsing, but can also be used to send files securely. This uses SSL/TLS encryption to safeguard data in transit, ensuring the privacy of sensitive data. This could be a better option if you don’t like having to install client applications for your end users and the majority of them are not technical people. It is even secure and very user-friendly.

Online browsers support HTTPS for file transfers which makes it a practical choice for businesses that regularly interact with web-based file transfer services. Additionally, it offers a high degree of security, with strong encryption algorithms and powerful encryption mechanisms.

WebDAVs

It should be obvious by now what that “S” stands for. This is a “secure” variant of Web Distributed Authoring and Versioning (WebDAV). WebDAVS operates over HTTP, meaning it demonstrates both the secure aspects of SSL and the same feature of WebDAV.

File servers vs. NAS vs. cloud storage

For whom is a file server appropriate?

It is a suitable storage medium for internal company files. It is a good fit for small to midsize businesses as bulk storage can be complicated to manage and it allows users to share files without manually transferring them.

What is NAS, and who can benefit from using NAS?

Network-attached storage (NAS) is a type of file-dedicated storage available for staff members or employees to efficiently collaborate over a network by providing data that is constantly accessible. It is suitable and helpful for businesses or offices and for photographers and video editors.

Cloud storage allows businesses to store, retrieve, and manage their data without having to manage and control their own data centers. It is suitable for individuals, organizations, and businesses as it is scalable and allows them to expand or reduce their data footprint. It also enables them to more easily store and manage their digital assets.

Essential Security Tips for File Servers

1. Don’t leave your server unattended. Aside from server theft, there are also risks of others hacking and controlling your server.
2. Keep your server patched or up-to-date to prevent unauthorized access to critical file servers because outdated and unpatched software creates vulnerability to attackers.
3. Apply Microsoft’s baseline secure settings to determine which features should be disabled because SMB v1 protocol is vulnerable to attacks.
4. Enable BitLocker encryption to add protection which can be crucial if physical security fails or hard drives are inappropriately disposed of.
5. Make sure that the password is unique and change it on a regular basis.
6. Keep permission simple.
7. Make sure to have a tested and secure backup.
8. Enable auditing of shares and folders so that the access and permissions are monitored and recorded.

Conclusion

That wraps up our discussion. It is evident that file servers play a vital role in efficiently sharing, managing, collaborating, and storing data as they provide secure and organized storage for multiple users to access. It enhances teamwork and cooperation and improves efficiency and productivity for everyone involved.
