Introduction
Using an FTP server is a common solution for businesses that want to keep their data secure. If you're looking for a convenient option to keep your data secure, a hosted FTP server could be the answer. Learn more about FTP servers, how they work, and how they can benefit your business.
What is File Transfer Protocol (FTP)?
You may have heard of FTP, or File Transfer Protocol, but you may not be sure what it is exactly. At its core, File Transfer Protocol is a way to connect two computers in the most secure way possible to help securely transfer files between two or more points. In simple terms, it is a way to share files between parties.
Secure FTP (SFTP) is increasingly being used today. MFTaaS providers like Sharetru offer cloud-based SFTP services. People often use SFTP (Secure File Transfer Protocol), also known as SSH File Transfer Protocol, instead of FTP (File Transfer Protocol) because of the security and advanced encryption features it offers. SFTP uses secure SSH (Secure Shell) connections and ensures that all data transferred between the client and server is encrypted, reducing the risk of unauthorized access or data interception.
It's important to understand the difference between FTP and SFTP. Unlike FTP, which transfers data in plain text, SFTP encrypts the entire session, including secure file transfers, directory listings, and user authentication. This added layer of security protects sensitive information such as login credentials, personal data, or confidential files, making it an ideal choice for businesses and individuals who prioritize data protection.
Additionally, SFTP uses a single port (typically port 22), which simplifies firewall configuration and improves network security by reducing the number of open ports. The combination of strong encryption, data integrity, and simple security measures makes SFTP the preferred option for secure and reliable file transfer.
How do FTP servers work?
FTP servers are solutions used to facilitate the process of transferring files over the Internet. If you send files using FTP, the files are either uploaded to or downloaded from the FTP server. When you upload files, the files are transferred from a personal computer to the server. When you download files, the files are transferred from the server to your personal computer. TCP/IP (Transmission Control Protocol/Internet Protocol), or the language that the Internet uses to execute commands, is used to transfer files over FTP.
FTP servers can be thought of as the middle point between the sender and receiver of a file. For FTP servers to work, you need a server address. Here's an example of what this address might look like: "ftp.examplecompany.net". Sometimes, the server address is given as a numeric address, such as "12.345.678.90".
Depending on the type of FTP server you are using and the level of security required, you may be required to enter a username and password. Some FTP servers allow anonymous connections, which do not require you to enter a username or password to access the server.
Desktop FTP clients and what they are used for
An FTP client is software that you run on your computer that knows how to talk to an FTP server. We call this the “client-server relationship.” When you connect to an FTP server, most of the time, you use an FTP client program. There are a variety of clients available for file transfers, with FileZilla, WinSCP, or Coffee Cup Free FTP being popular choices.
FTP clients provide features that facilitate FTP transfers and simplify communication with the server. They often support drag-and-drop interfaces and offer easy ways to synchronize folders. Behind the scenes, FTP clients interpret the actions performed in their interfaces and translate them into FTP commands, which the server understands.
In general, an FTP client acts as a bridge between your computer and the FTP server, enabling seamless interaction and efficient file transfer.
Connecting to and using an FTP server
To connect to an FTP (File Transfer Protocol) server, you can use the ftp command-line tool on most operating systems. Simply search for it in your applications. Here is an example command to connect to an FTP server:
Replace ftp.example.com with the hostname or IP address of the FTP server you want to connect to. If the FTP server uses a different port than the default (21), you can specify it using the -p option followed by the port number:
After running the command, you will be asked to enter your FTP server credentials such as username and password to complete the connection. Then you can start giving FTP server commands.
Vital commands that an FTP server can perform
An FTP server provides a wide range of commands that allow users to perform various operations for managing and transferring files. These commands allow users to navigate directories, upload and download files, delete and rename files, set file permissions, and manage remote connections. In addition, FTP servers often support commands for retrieving information about the server, listing directory contents, and configuring server settings. Some common FTP commands include:
- USER – Verify a user by username.
- PASS – Verify a user with a password.
- CWD – Change the current working directory.
- PWD – Print the current working directory.
- LIST – Table of contents of a list.
- RETR – Retrieve (download) a file from the server.
- STOR – Save (upload) a file to the server.
- DELE – Delete a file on the server.
- RNFR – Change the “from” file name.
- RNTO – Change the name of the “to” file.
- SITE – Execute server-specific commands.
- HELP – Get help with information about FTP commands.
- QUIT – Disconnect from the FTP server.
These commands, among other things, provide users with the tools necessary to effectively interact with an FTP server and manage their files effectively.
How to use an FTP server for script commands
Additionally, FTP servers can be used to script automated commands. FTP servers offer tremendous versatility for automation and scripting, enabling seamless and efficient file management. With the power of scripting, you can automate repetitive tasks, synchronize files, and streamline workflows. Here are five examples of scripts that can be done with an FTP server:
- Backup script: Create a script that connects to an FTP server, retrieves specific files or directories, and moves them to a local backup location. This script can be scheduled to run at regular intervals, ensuring data redundancy and disaster recovery.
- File sync script: Create a script that compares the contents of a local directory with a remote directory on an FTP server. It detects differences and transfers only modified or new files, maintaining synchronization between the local and remote locations.
- Batch file upload script: Create a script to automatically upload a batch of files to an FTP server. This can be useful for scenarios like website maintenance, where multiple files need to be uploaded at once, eliminating the need to manually transfer files one by one.
- File recovery script: Create a script that connects to an FTP server, navigates to a specific directory, and retrieves files based on specific criteria such as file type, size, or timestamp. This can help extract specific data or collect reports from the server efficiently.
- Automatic data exchange script: Design a script that coordinates data exchange between different FTP servers or systems. This script can handle complex workflows, including fetching files from one server, converting or processing them, and then automatically transferring them to another server.
These examples demonstrate the potential of scripting with an FTP server, allowing for time-saving automation, data management, and improved efficiency in file-related operations.
5 Benefits of FTP Servers
Although FTP is one way to transfer files, there are certainly other options. So, what are the advantages of using FTP over other transfer tools? Here are five advantages that companies can enjoy when using FTP servers as opposed to other transfer options.
Increasing the security of FTP servers
Ultimately, the biggest advantage of using FTP servers over other options is the level of security that these managed options can offer. FTPS and SFTP, both secure (encrypted) file transfer protocols, add another layer of security to traditional FTP transfers, and many FTP servers support FTPS and SFTP to better protect the data being shared. This gives you the peace of mind that your sensitive files won’t fall into the wrong hands, as they’re encrypted during transfer.
It is also important to understand the difference between explicit FTPS and implicit FTPS. Explicit FTPS and implicit FTPS are two different modes of secure file transfer protocols. While both modes provide encryption for FTP transfers, there are key differences between them. Explicit FTPS provides more flexibility and compatibility, while implicit FTPS is an older mode that is less secure and less widely used. Understanding the differences between these modes is important to choose the right one for your specific needs.
When you send data, especially sensitive data, you may be concerned that other parties will intercept your transmissions. Anyone with the right tools or a little knowledge can intercept files. You may also be concerned that your transfers are vulnerable to viruses or other malware. Fortunately, when you use a managed FTP server, the vendor is responsible for providing the security needed to keep your data safe.
Improved control of FTP servers
Another advantage of using an FTP server is the level of control you can gain over your data. Many FTP servers, especially the industry-leading ones, offer granular access controls that allow your administrators to determine who can upload, download, edit, delete, or share files. And what folders they have specific permissions on.
Not everyone in your organization needs the same level of access to your files. For example, your finance manager may need to see sensitive financial records, while your intern may not. The ability to control file access and resolution based on individual user accounts can add additional security to your files.
Ability to share large files
Have you ever tried to send a file to a recipient via email, only to receive a message that your file is too large to send? If your organization deals with massive amounts of data, you don't want your entire file sharing process to be interrupted due to the large size of the files. Instead, you can use an FTP server that allows you to send up to a gigabyte of data at once.
Improved workflow for IT systems
Having a file sharing process that isn't consistent across your organization can hurt your business productivity. Instead of sharing one file at a time, you can send large amounts of data at once. You can also continue working while making large transfers, or schedule bulk transfers for nights or weekends so your workflow isn't interrupted.
Also, having an FTP server gives you a single place to store all your files. This reduces the amount of time your team spends hunting down a specific piece of data. It also reduces the chance of losing files.
Automated backups for disaster recovery
You never know when you might encounter lost or compromised data. When you choose a top FTP provider, your vendor can ensure that your files are never lost, from everyday data to your most important and sensitive files.
When disaster strikes, such as an internet outage, power outage, or even an actual natural disaster, you don't have to worry about losing your work. Instead, your data is backed up regularly and automatically to another location. Then, if you need to restore your data, you can do so by coordinating with your FTP vendor.
Knowing a little more about what FTP servers are and the benefits of using them will allow you to make the best possible decisions about your data. Storing your data in secure locations will give you the assurance that it will be safe from disaster or risk. Make sure to partner with an FTP vendor that can offer you all of the benefits listed above.
FTP Servers vs. File Services
If you're trying to determine which option is best for your company, it's important to consider the differences between FTP servers and file services. FTP servers are designed specifically for file transfer and management, and offer a wide range of commands and functions to facilitate efficient file sharing and collaboration. File Services, on the other hand, offer a more comprehensive solution for storing, organizing, and sharing files in a centralized system.
FTP servers excel in their ability to handle large file sizes and facilitate fast and secure transfers. With FTP servers, you can easily upload, download, and manage files remotely, making them ideal for scenarios where file sharing and collaboration are the main focus. Additionally, FTP servers offer advanced security features such as encryption protocols like FTPS and SFTP, ensuring that your sensitive data is protected during transit.
File Services, on the other hand, offer a wider range of capabilities beyond file transfer. They provide a centralized file storage system with advanced features such as version control, file synchronization, access controls, and collaboration tools. With File Services, you can create a structured file hierarchy, set permissions for different users or groups, and track changes made to files over time. This makes File Services a more comprehensive solution for managing and organizing large volumes of data in an organization.
When deciding between FTP servers and file services, it's important to consider your specific needs and preferences. If your primary need is efficient file transfer and collaboration, an FTP server would be a good choice. However, if you need a more robust solution that includes file storage, organization, and advanced collaboration features, File Services would be a better option.
Result
Ultimately, the decision between FTP servers and File Services depends on the size and nature of your organization, the volume of data you need to manage, and the level of control and security you require. By carefully evaluating these factors, you can make an informed decision and choose the solution that best suits your company's needs.
