What's New in Raysync V5.0.8.8?
Recently, Raysync released its new version V5.0.8.8. In this article, we'll interpret the eight new functions of V5.0.8.8 in detail, let's have a look! 1. Add "Delete files automatically " option 1) Click "Local storage" in the Storage option, you will find the local storage details and file delete option. The file delete setting only supports non-third-party object storage. 2) Check "Delete files automatically", it supports set automatically delete files which accessed/modified X days ago. For example, you could set automatically delete files that accessed seven days ago. 3) Set the directory to recycle the deleted files. All files automatically cleaned by users will be recycled to this directory, where users can retrieve files or clean files with one click. 2. File transfer in priority When there is more than one task waiting to be transmitted to the client, the task will be transferred in sequence. If you want to transfer one of the tasks in priority, you could click the "Top priority" icon to sort all the transfer tasks. 3. Add Google cloud storage Google cloud storage is added to the third-party cloud storages. 4. Support copy and paste the file path Raysync supports copying and pasting the file paths. For files with a deep directory, you could copy the path and forward it to your partners, and the they can quickly access the designated file/folder by pasting the path, which saving the time of step-by-step clicking. 5. Support query download times and user IP You could query about the download times and IP address of the shared files with this new function. 6. Support set the number of transferred files in parallel In general, the number of transferred files depends on the number of CPU-core. In V5.0.8.8, we add a new function to set the number of transferred files in parallel. Note: if the number you set to transfer in parallel exceeds the quantity of CPU cores, files will still be transmitted according to the number of CPU cores. 7. Support set whether to enable password for file sharing Raysync V5.0.8.8 supports enable or disable the sharing password. Besides, users are supported to custom the passwords . 8. Both files and folders can be selected for uploading Raysync optimizes the file uploading function, the new version supports selecting files and folders to upload at the same time, making it easier for users to operate and use.
What Technology does Raysync Adopt to Transfer File Cross-border?
Cross-border large file transfer and transnational transfer have to face the network transfer environment of ultra-long distance and weak network. If you want to transfer files fast, read on to learn how professional file transfer software Raysync transfers. For Congestion Handling: - More effective congestion judgment and treatment. - The recovery mechanism of packet loss judgment is carried out more accurately and timely. At present, the mainstream congestion judgment is designed based on the network situation data back to twenty years ago, and its basic assumption is that any packet loss reflects the network congestion. This assumption is completely out of line with the modern network situation. Packet loss in modern networks is often not caused by congestion factors. This disconnection leads to the transfer protocol often entering an overly conservative transfer state. The congestion detection algorithm of Raysync transfer protocol automatically collects the existing background transfer information on the path, and accurately judges the actual congestion situation according to the transfer speed, which is neither too conservative nor too radical, and can effectively make full use of the path bandwidth. For Packet Loss: - The standard TCP protocol tells the packet loss from two methods. - The receiving end continuously confirms the number of Dup-ACK. - ACK timeout. When the situation of packet loss always happens, the ACK is needed to judge the timeout and trigger to retransfer. Packet loss in modern networks is often burst, and it is common for multiple data packets to be lost at the same time on a connection. Therefore, standard TCP often relies on time-out to retransmit holes, which often leads to a waiting state of several seconds or even ten seconds, which makes transfer stagnate or even interrupt for a long time. This is one of the main problems affecting the efficiency of standard TCP. Raysync transfer protocol abandons TCP protocol's practice of using transfer message sequence as both transfer byte count and reliable transfer confirmation identifier and designs a brand-new ACK data algorithm. According to the ACK information returned by the transfer receiver, the transfer sender can accurately judge the packet loss and retransfer the data at the first time, instead of relying on the cumulative acknowledgment of multiple acks or the ack timeout timer to trigger the data retransfer, which greatly improves the transfer speed and transfer real-time. Raysync transfer protocol can make full use of large bandwidth network and transmit data at the fastest speed. In the application scenario of mass data distribution, it can help users to complete big data transfer and cross-border file transfer in the least time.
[2022] Full Guide - FTP (File Transfer Protocol)
Part 1: What is File Transfer Protocol ? File Transfer Protocol is a set of standard protocols used for file transfer over the network, which works at the seventh layer of the OSI model and the fourth layer of the TCP model, i.e., the application layer. This ensures that the connection between the client and the server is reliable and connection-oriented, providing a reliable guarantee of data transmission. Part 2: How does File Transfer Protocol Work? File Transfer Protocol uses the user interface of the Internet's standard file transfer protocol, FTP, to provide users with a set of applications for managing file transfers between computers. FTP is designed based on the client-server model, where two communications channels are established between the client and the FTP server. Command Channel cannot perform the task of transferring data and can only be used to transfer control information such as internal commands executed by FTP and the responses to the commands; Data 12Channel is a connection for transferring files between the server and the client, which is full-duplex and allows simultaneous data transfer in both directions. This idea of separate transmission of commands and data greatly increases the efficiency of FTP, while other client server applications typically have only one TCP connection. Th121 client initiates a conversation with the server when the user requests the server to download a file. Using FTP, the client can upload, download, delete, move, and rename files on the server. Part 3: Two Modes of FTP FTP client initiates FTP session and establishes corresponding connection with FTP server. Two channels are to be established during FTP session: control information process and data process. Standard : Standard mode FTP client sends PORT command to FTP server. Passive : Passive mode FTP client sends PASV command to FTP Server. Part 4: FTP Transfer Method The task of the FTP is to transfer files from one computer to another, independent of the location of the two computers, the way they are connected, or even whether they use the same operating system. There are two ways to transfer FTP: ASCII, Binary. ASCII Assuming that the file the user is copying contains simple ASCII text, if the remote machine is not running UNIX, when the file is transferred ftp will usually automatically adjust the contents of the file to facilitate the interpretation of the file into the format in which the text file is stored on the other computer. Note: It is often the case that the file the user is transferring contains files that are not text files; they may be programs, databases, word processing files, or compressed files. Before copying any non-text files, use the binary command to tell ftp to copy them. Binary In a binary transfer, the bit sequence of the file is preserved so that the original and the copy are bit-by-bit one-to-one. Even if the file containing the bit sequence on the destination machine is meaningless. Note: If a binary file is transferred in ASCII, it will still be translated even if it is not needed. This can corrupt the data. Part 5: User classification of FTP Real Account This type of user is the one who has an account on the FTP service. When this type of user logs in to the FTP server, their default home directory is the directory named by their account. However, they can also change to other directories. For example, the home directory of the system, etc. Guest User In FTP server, we often set up an account for different departments or a specific user. However, this account has the feature that it can only access its own home directory. In this way, the server secures other files on the FTP service. An account with this type of user can only access the directories under its home directory, but not files outside its home directory. Anonymous User This is also what we usually call anonymous access. This type of user is not assigned an account in the FTP server, but he/she can still access some public resources anonymously. Part 6: The Development of FTP FTP is the oldest network tool in the development of the Internet. From 1971, when the first RFC for FTP was proposed by A KBHUSHAN to nearly half a century ago, FTP has been one of the most important and widely used services in the Internet with its unique advantages. With the continuous development of the Internet, the FTP specification has undergone several revisions to accommodate network standards including TCP/IP. In 1980, jon postel, a scientist at the Institute of Information Science at the University of Southern California, defined a new version of FTP in RFC 765. In 1985, RFC 959 redefined FTP, this time introducing new administrative features, including the ability to create and delete file directories. In 1997, REC 959 was updated to provide new features defined in RFC 2228 to provide security features. In 1999, FTP was updated to RFC 2428 to support the IPv6 protocol. Part 7: 7 Common File Transfer Protocols FTP FTP is a network protocol for transmitting files between computers over Transmission Control Protocol/Internet Protocol connections. Within the TCP/IP suite, FTP is considered an application layer protocol. FTPS FTPS a multi-transfer protocol, equivalent to an encrypted version of FTP. When sending and receiving files on the FTP server, you face two risks. The first risk is to encrypt the files when uploading files. The second risk is that these files will stay on the FTP server while waiting for the recipient to download them, at which point they need to be secured. Measure: Choose to create an FTP server that supports SSL, i.e., use an encrypted control and data channel with an SSL layer under the FTP protocol to allow the host to upload these files using an FTPS connection. TLS & SSL TLS is an industry standard designed to protect the privacy of information during network communications, allowing client and server applications to detect security risks including message tampering, message interception, message forgery, and its predecessor, SSL. TLS and SSL encrypt network connections at the transport layer, but work below the application layer. SSL security extensions have at least two different initialization methods: explicit security and implicit security. SSH(Secure Shell) SSH is a security protocol based on the application layer. SSH is currently a more reliable protocol that provides security for remote login sessions and other network services, and the use of SSH protocol can effectively prevent the leakage of information during remote management. SCP The SCP protocol is an application layer protocol that defines the process of transferring files "between local and remote machines" or "between remote and remote machines". The SCP protocol is based on the SSH protocol, so file transfers based on the SCP protocol are secure. SFTP SFTP is a secure file transfer protocol that provides a secure encryption method for transferring files. It has almost the same syntax and functions as FTP, but SFTP is part of SSH, a secure way to transfer files to a server. SFTP also uses encryption to transmit authentication information and the transmitted data, so it is very secure to use SFTP. However, because this transfer method uses encryption/decryption technology, the transfer efficiency is much lower than normal FTP. If you require higher network security, you can use SFTP instead of FTP. HTTP & HTTPS HTTP is the basis for data communication. It defines the message format for communication between a Web browser and a Web server, and how the Web browser should respond to Web requests. HTTP uses TCP as the underlying transport and is a stateless protocol. This means that each command is executed independently and the receiver does not retain session information. Https is a secure version of HTTP in which communication is encrypted via TLS or SSL.

This Powerful Data Transfer Solution is Used by 99% of Companies
FTP protocol originated from the early days of network computing. A few government and university researchers explored the value of connecting computers together, so they created FTP protocol to promote the movement of files in the network. Why do so many people still use FTP now? Because it is perfect and embedded in most operating systems today. Although FTP is provided free of charge, it does not mean that it has no cost. IT teams spend too much time managing and maintaining FTP servers and their users, which could have been devoted to more important IT projects and plans. Security Many changes have taken place in FTP since it was invented, especially the security and confidentiality. FTP predates the Internet as we know it today, but it is not designed to transfer files safely. When companies use it to send files containing personally identifiable information or patient data, compliance does not exist. FTP has no resistance to many types of attacks, and the user name and password credentials are sent in clear text. It is not difficult for hackers to extract information and access the entire server containing company data. Ease-of-use FTP is mainly an IT tool. Many IT professionals still like to run FTP in command line mode, and take pride in managing servers through text commands, but for ordinary knowledge workers, FTP operation is too technical. FTP client software can help, but it is only an overlay, which will not increase security or reduce manual management of FTP server. The complaints that FTP administrators often hear are managing users and their credentials, and knowing which files should be saved on the server and which files can be deleted. This causes the FTP server to become very bloated. As time goes by, the files on the FTP server continue to accumulate, and the situation will get worse and worse. What transfer tools do we use now? Today's file transfer function has surpassed FTP many times, providing encrypted communication, reporting and tracking functions, integrating with enterprise applications, and being more intuitive. High-speed file transfer solutions can meet today's growing demand for secure file transfer. It's time to adopt a more modern and powerful data transfer solution. As time goes by, your company will benefit from this, operate within the scope of compliance standards, and become more efficient after the final rest of FTP.
