What is the difference between FTPS and SFTP? Let us first look at the technology behind each protocol, and then look at its advantages and limitations. What is FTPS? So what does FTPS stand for? The file transfer protocol is secure. FTP first appeared-but it was not initially secured. FTPS uses Secure Sockets Layer or Transport Layer Security protocols to provide connection security through encryption. This is provided by the public key certificate of the FTPS server in x.509 formats. The certificate can be trusted or self-signed. Using a self-signed certificate does not mean that the encryption level will be lower, but you must ensure that the host is who they say it is. Implicitly or explicitly make FTPS connections secure. FTPS servers usually listen for implicit connections on port 990 and explicit connections on port 21-although the server administrator can of course choose to use other ports as needed. How Does FTPS Work? The implicit connection starts when the client sends a TLS "client hello" message. This message indicates that the connection should be secure. If the server does not receive the connection, the connection will be disconnected immediately. However, if the server does receive a "client hello" message, it sends the server certificate to the client, and the client will authenticate it and use it to encrypt the session key, and then send it back to the server for the conversation encryption. For explicit FTPS, the client explicitly requests security by sending the "AUTH TLS" command immediately after establishing the connection. If the AUTH command is not sent, the FTPS server will treat the client connection as a "regular" non-secure FTP session. Interestingly, implicit connections are not listed in RFC 2228 , only explicit connections. In either case, once the session starts, the client will need to authenticate to the FTPS server-usually, this will be authenticated by a user ID and password, but can also include a client certificate if needed. All FTP commands are naturally passed along the control channel , but FTPS then requires a separate channel for data communication . By default, the data channel is port 20 for explicit FTPS and port 989 for implicit FTPS. The data channel is opened as needed and then immediately closed again . What is the Difference Between FTPS and SFTP? First of all, SFTP is not a form of FTP. In fact, FTPS and SFTP are completely unrelated and only have similarities in the structure of many commands. SFTP is not an FTP connected via SSH, but an independent protocol in itself, which uses the basic SSH protocol to provide connection security and identity verification. Because it uses the underlying SSH protocol, it is normal to use the SSH port . With SFTP, we no longer use certificates for encryption but instead use public/private key pairs that are not signed by a trusted authority. Just like the FTPS self-signed certificate, the only thing that can be doubted is who the SFTP server should be—once you are sure that you are connected to the correct server, you just need to accept the server key and continue the encrypted session.
How to transfer large files quickly? It has become a problem that people must understand in work and life. There are many ways to transfer large files. You can refer to the methods of the large file transfer: In fact, in the Internet age, speed has determined efficiency. In the production process of the enterprise, information and data exchange and transportation are required. At this time, a large file transfer is required. Many industries need to transfer large files. For example, the film and television industry needs to transmit video materials every day. A video as small as tens of megabytes and as many as several terabytes of video data must be transmitted from the shooting location to the video center for editing and rendering. For example, the meteorological observation points in the meteorological industry need to conduct real-time weather observations, and the data can be summarized to the Meteorological Bureau in real-time to issue accurate and correct weather forecasts. For example, Internet technology companies and big data analysis companies need to receive various data materials from various industries. For example, large enterprises need to transmit the financial data of each branch to the headquarters for summary at the beginning of each month. At this time, in the face of such a huge amount of data, how can companies ensure the safety, stability, and efficiency of large file transfer, then large file transfer software is indispensable for enterprises. For now, there are many file transfer software on the market. Small file transfer software can use network sharing software such as QQ, mailbox, etc. to transfer. A point-to-point transfer is still very convenient, but there is a limit to the file size, and the speed is sometimes slow depending on the network environment. But it is also a good choice for individual users to transfer small files. The transfer of large files using FileZilla, network disk, etc. is relatively stable and can support resumable transfers, but the speed will become slow when transferring large files, and the data packet loss rate is large, the transfer reliability is poor, and the speed is particularly low during international transfer. obvious. If you use a network disk, it will be inconvenient to operate, and you need to upload the file to the terminal before downloading it. Besides, there is another way for large files, which is to send a large number of files to the destination. However, unpredictable problems such as damage to the hard disk and delays in express delivery may occur during the transportation, and the real-time performance cannot be achieved. , Which limits the efficiency to a certain extent. If it is an enterprise-level large file transfer, you can choose to use the Raysync software. Raysync is an enterprise-level transfer product for enterprise large file transfer, adhering to the purpose of faster, more dazzling, more stable, and more powerful. The file transfer is very good.

File transfer is the core of business operations. The company regularly exchanges data internally with customers, suppliers, and partners every day. Whether they need to transfer batch transactions to an outsourced payroll provider or need to send digital video for marketing activities, they must be able to transfer data safely and efficiently. Organizations continue to rely on file transfers to share digital information. More than 50% of all system integration is done through file transfer. "From banking and financial services to defense and manufacturing, the transfer of critical business data is crucial," Todd Margo said in his IBM-managed file transfer blog. "For the business to run smoothly, it is necessary to move, copy, synchronize, and share the ever-emerging and developing digital data forms packaged in the form of files." He went on to describe some of the factors that affect today's file transfer requirements: Data volume: Compared with the past, the workload requirements for file transfer are high-frequency batch processing and larger and more diverse files. Innovative applications for streaming are also needed. Big data and the Internet of Things: Companies are deploying file transfer technology to enable batch transaction file exchange in areas such as the Internet of Things and big data analysis. This can greatly increase the data transmission speed. Besides, the amount of data is increasing to support more detailed analysis. The two punches of speed and file volume pose special challenges to file transfer technology. Security: Network security issues continue to intensify, leading to the adoption of better security technologies. When possible, the file transfer system should compensate for the security overhead by supporting hardware accelerators, new security processing software, and improved file transfer throughput. According to the analyst report: "Non-compliance with data security and privacy regulations and lack of end-to-end visibility and monitoring are still the main issues facing the functionality of existing file transfer solutions." The report further added: Cloud-enabled, via API Simplified integration, and improvement of user experience are the subject of development. SFTP FTP and Secure FTP are the most widely used file transfer methods. Part of the appeal is that they are easy to use, usually free or cheap. The transfer is usually done through an FTP website that most people can access. If the organization occasionally needs to send non-sensitive documents, this technique works well, but if it is widely used, it may put them at risk. Recent studies have shown that more than 400 million files from FTP servers are available online. When exposing files, FTP does not log security violations or verify user identity-this is a basic function needed to help detect and prevent vulnerabilities or cyber threats. The technology also sends files on a first-come, first-served basis. Therefore, organizations cannot determine the priority of critical transmissions or quickly respond to business needs. To overcome the hidden costs and risks of FTP, more and more companies choose secure and scalable file transfer software.
Aiming at the problem of the transnational transmission of large files, we break down the problem into two small problems, so it is easy to draw a final conclusion. The factors that influence the transnational file transfer: Clarify the size of the enterprise's files Considering the problem of cross-border file size is mainly due to the high latency, high packet loss, and transmission interruption in cross-border transmission. FTP, the earliest open-source transmission tool in the market, supports transnational file transmission, but the speed of large file transmission can not keep up with the demand of large file transmission of enterprises; E-mail, network disk, and other transmission methods are also convenient. Transnational transmission is also faced with the same problems, such as limited speed and limited file size. Only small file transmission can be realized, and it cannot be considered in the case of massive small files. The fundamental needs of the required file transfer are clarified, and we can go to the next step to understand the influencing factors of the transnational file transfer. Small file transfer: mail and network disk can be easily solved. Large file transfer needs to consider factors of different aspect: transfer speed, stability, security, and ease of use. Raysync is equipped with the tool software of Raysync ultra-high-speed transmission protocol independently developed by Raysync, which perfectly explains the influencing factors and solutions of transnational file transmission, large file transmission, and massive small file transmission from the following six aspects. - High-speed Through the built-in high-speed transmission protocol, intelligent compression, and other technologies, the transmission speed is increased to 100 times that of FTP. At the same time, it automatically and intelligently optimizes the network bandwidth, makes full use of the existing bandwidth, effectively reduces the influence of network latency and packet loss, and realizes the high-speed transmission of ultra-remote, cross-border large files, and massive small files. Efficient and stable performance without special adjustment. - Stability In the transmission process, in order to ensure the stability and integrity of data transmission, Raysync adopts the mechanisms of breakpoint resume, error retransmission, multiple file check, intelligent synchronization, etc., to ensure that data transmission can be effectively guaranteed when network failures and abnormal transmission occur during the transmission process, and at the same time shorten the output time and reduce the workload. - Security In order to ensure the security of data transmission and prevent data leakage, cracking, monitoring and other security issues, Raysync strengthens the security control of internal data communication, adopts AES-256 encryption technology of online banking, and uses SSL encryption transmission in the transmission process to effectively ensure data security. At the same time, the Raysync adopts the setting of access rights and OS rights, thus achieving stricter access control. - Ease of use It takes easy steps to deploy and install Raysync in 30 minutes. At the same time, Raysync supports UNIX, Linux, Windows, and other common operating systems, supports Alibaba Cloud, Amazon Cloud, Huawei Cloud, and other cloud platform operating systems, and provides special SDK integration products, which can quickly integrate and deploy with existing systems of enterprises, and easily build a high-speed transmission network environment between multinational enterprises and an automated file transmission network of heterogeneous systems. - Multi-mode transfer Raysync supports providing multiple modes of transmission according to different transmission initiators. Support point-to-point, multi-point mutual transmission, data cloud transmission, one-to-many data distribution, and other modes. Provide exclusive user and user group space, support specific authority management, and build exclusive assistance space and file transmission requirements across departments and companies. - Global central control The system provides effective management modules for data transmission log, user operation log, user management, and user authority management. By adopting the policies of system control, document access fine granularity authority, data leakage prevention, and sharing authority, the system can ensure the effective control of data during transmission and storage, ensure the safety of sensitive information, trace the flow of data transmission content and create a stable and controllable data transmission security environment. The Raysync ultra-high-speed transmission protocol independently developed by Raysync breaks through the transmission defects of traditional FTP and HTTP, the transmission rate is increased by 100X, and the bandwidth utilization rate is over 96%, which can easily meet the extremely fast transmission requirements of TB-level large files and massive small files. There are many computer rooms at home and abroad. Compared with the same products in the market, the speed and security performance in transnational file transmission is excellent.
File transfer accelerators are not unfamiliar to everyone. If you want to transfer files faster than others, especially in the face of large file transfers and massive small file transfers, it can solve the acceleration problem in the file transfer process, then it can improve the file transfer The efficiency reduces the file transfer time. Why use a file transfer accelerator? Because traditional file transfer methods can no longer meet the needs of people's daily life, with the continuous increase of file size and volume, the demand for file transfer is also expanding. Users in the workplace urgently need a tool to quickly transfer files to meet the needs of their work, so file transfer accelerators came into being. Let me introduce you to the Raysync file transfer accelerator, which can increase the speed of file transfer and reduce the delay and packet loss rate of the file transfer. The Raysync file transfer protocol FTP acceleration product is a high-efficiency transfer software specially developed for enterprises that completely replaces the existing file transfer protocol FTP. It can realize high-speed file transfer on the basis of the existing structure and uses the Raysync file transfer protocol FTP to accelerate Later, the file transfer protocol FTP transfer speed can be increased by 10-100 times The transmission speed is hundreds of times faster than that of FTP and HTTP, which maximizes the bandwidth without affecting other network traffic. Among them, the transmission of massive small files under the same network environment is 6000 times faster than FileZilla. Cross-regional and cross-border big data replication, migration, or archiving can transfer at least 100TB of data per day.
