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.

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.

With the iteration and development of information technology, the information and technical barriers between traditional media in different forms, such as newspapers, television, and radio, have been broken, and the boundaries between traditional media and new media, such as the Internet, have been gradually dissolved. For media organizations specializing in content production, audio transmission, video transmission, text, pictures, and other file contents are the cornerstone of their survival and development. How to quickly realize content collection, production and distribution is the source power for the industry to maintain its leading position. This year, the bubble of broadcast media has certainly expanded, and new content forms are appearing in the whole industry. Obviously, remote collaboration and other new productivity methods must be implemented in the workflow to make the production successful. What needs to be emphasized is how the industry will continue to develop with the help of acceleration tools. Media producers have noticed an increase in workload. Each department needs to produce media materials with different stages and huge data volume, and smooth collaboration and effective data migration are needed among departments. These files will have different sizes and formats, so it is necessary to use fast file transfer tools to deal with files of any size among various departments of the enterprise. Before introducing a solution similar to the large file transfer system with radium speed, many enterprises had the problem of low team productivity. Of course, enterprises can study appropriate tools, but it needs to invest a lot of manpower, material resources, and money. Some companies choose to simplify this process, but it also leads to data confusion, leakage, and other security issues. Choosing suitable tools can actually provide the correct direction and guidance for enterprises. Raysync will guide big data enterprises to complete correct high-speed large file transfer steps. Raysync large file transmission system is a popular transmission tool in the whole film and television media industry. It is a set of server and client applications, which can accelerate point-to-point file transmission at a speed of up to 10 Gbps.

What's Shadow IT? Gartner analyst Simon Mingay wrote in a research report that Shadow IT in a broad sense includes "investment in the acquisition, development and/or operation of IT solutions outside the formal control of formal IT organizations". To put IT simply, Shadow IT refers to a department or individual who uses IT-related hardware or software without knowing the IT or security group in the organization. In reality, employees in general enterprises rely on software that has not been approved by IT departments. Business departments bypass IT departments and use applications on the cloud to complete their work efficiently and quickly. These are also called "shadow IT". Although "shadow IT" and "business value" doesn't sound directly related, using shadow IT is quite simple and direct. But when shadow IT was exposed, IT revealed many security vulnerabilities to IT departments. Enterprise employees can easily bypass the IT team's approval, but they cannot check the reliability and security of the selected application in depth. Employees unconsciously input important enterprise data into unauthorized cloud services, which makes enterprise data security a gamble directly. In fact, nearly 80% of employees in general enterprises rely on this software that has not been approved by IT departments. Faced with this situation, what should IT leaders do if they find that these unsafe applications are being used by employees or are sharing sensitive information? It's obvious that it's natural to react quickly and demand that these applications be stopped immediately and that employees who violate the company's data security regulations be punished. However, the value gained by IT leaders from the discovery of Shadow IT is equally important for future IT decisions. What is the problem with Shadow IT? If IT executives find that employees are using free file sharing applications, the next step is to find out why employees use them. For what reason do so many employees bypass FTP and other systems and secretly use these applications for file sharing? Only by breaking the root cause of Shadow IT entering the enterprise can we improve the current situation of the enterprise and truly protect the data security of the enterprise. It's easy to find out that many employees express their weakness in the processing efficiency of existing enterprise application systems. FTP is time-consuming and complex, and email is limited by attachment volume, so professional software procurement costs are high. The huge amount of data and the impatient urging of customers make them need a fast way to transfer files. Although the situation of each enterprise is different, fundamentally, the biggest reason for employees to use these file transfer software is that they can handle their work at any time and anywhere with a low cost or even zero cost. Breaking Shadow IT and Solving Enterprise Application Compliance Problems Recognizing the above problems, we will find that it is not enough to order employees to stop using unsafe file sharing applications. No matter how hard IT leaders try to control the organization's data, employees can choose unsafe solutions. Enterprises can choose compliance solutions such as Raysync. The goal of Raysync is to help enterprises and IT departments solve the normative problems of file sharing and provide easy-to-use and high-speed file transmission solutions for enterprise employees to improve office efficiency. Enterprises using Raysync software can use account management to help control file flow, and the high-speed transfer engine independently developed by Raysync can meet the extreme speed transfer of TB-level large files and massive small files. Raysync is flexible enough to meet the various demands of enterprises. At this stage, Raysync introduces the flow version, which can be purchased by enterprises according to their needs. Enjoy the file transfer service of Raysync professional version at low cost, effectively control the cost consumption, eliminate the waste of resources, and realize the cost optimization. It provides a one-stop enterprise-level large file transfer solution, and it is an efficient way to obtain policy cooperation between employees and companies.

With the vigorous development of new technologies such as cloud computing, big data, the Internet of Things, and artificial intelligence, large-scale new applications have facilitated my life. But at the same time, hackers, who are tempted by the interests of black products, also turn their eyes to this place, and they have targeted attacks, again and again, thus directly plundering enterprise data resources and important customers. Here are our 5 tips for improving your data security: 1. Troubleshoot computer network system vulnerabilities The computer network system is composed of computer hardware, software, and client network system configuration. The first step of enterprise self-examination is to carry out daily maintenance of its own hardware equipment; Secondly, it is also the key point to check the compliance and security of software systems, clean up the non-compliant and unsafe third-party applications used by employees in time, update the conventional systems, and investigate loopholes; The other is to configure the client's network system safely. 2. Is the data using standardized The second point of self-examination of enterprise data security is to standardize the management of enterprise data use. Enterprises have a clear positioning of safety standards, and the practicality of specific data usage specifications is usually reflected in employees' daily work. Especially in file transmission, the transmission process is the hardest hit by network attacks, and the control of data flow is also very important. Just as many Internet companies are doing, it is necessary to manage the access, editing, and downloading rights of sensitive data, which plays a protective role in data security to a certain extent. 3. Investigate employees' safety awareness At present, nearly half of cyber-attacks are caused by the lack of security awareness of enterprise employees, which directly or indirectly leads to data leakage. The employees' awareness of the importance of data and network attack methods is directly related to their sensitivity to the possible security threats and potential attacks of current data. Many enterprises tend to ignore the safety control of employees. Do your employees really know what might be a cyber attack? Data security training is a good way for employees' safety awareness. Establish a culture so that employees can quickly perceive potential threats and report suspicious cases in time. The above self-inspection method is based on three key factors of data security, and the other two points we want to mention are the self-inspection method of security control of dynamic data. 4. Data flow direction "High-speed data transfer creates value for enterprises" is the service concept of Raysync. On the contrary, this sentence is essentially the normal state of enterprise business transfer. Every day, a small and medium-sized enterprise produces no less than 10GB of data, and where this data flow is actually a security blind spot for many enterprises. At present, there are more and more ways of online data interaction, and various ways of data interaction facilitate people's work, but also greatly increase the difficulty for enterprises to supervise data security. To solve this problem, let's take a look at how the enterprise-level file transfer expert Raysync deals with it. - Transmission management and control: add transmission strategy, transmission reality, and transmission log design, and the administrator can take a glance at the transmission of sub-accounts; - Supervision of document outgoing: all documents outgoing are under management supervision. In the face of sensitive data leakage, the administrator can directly interrupt the sharing of relevant documents; 5. Grade authority Dividing data grades and employee categories is the key to building an enterprise data safety net. Hackers and system vulnerabilities are the main reasons for data leakage incidents. Some conscious and unconscious operation behaviors of employees in their daily work are easily manipulated or misled by cybercriminals, and the data level they come into contact with is the height of enterprise information assets that criminals can reach. Grant local administrative authority only when necessary, assuming that the network attack against the enterprise is successful , and the infected computer cannot easily spread malicious software to other devices in the network, which plays an important role in curbing the attack scope. In view of this, many applications can do it at present. For example, several functional designs of data authority such as identity authorization, user grouping, and security encryption in Raysync run through the whole process of data security transmission, which is a good way to protect enterprise data security. Data flow transfers data to create greater value. Today, with the rapid development of science and technology, the process of data interaction is both an opportunity and a challenge for Internet enterprises, as well as hackers.

Data transfer has played an important role for enterprises to conduct business with its customers, partners and suppliers while acting as its foundation in mining data value. However, the emergence of the Big Data era has spawned a massive amount of data, while various data types and interactive scenarios have become increasingly complex, the efficiency and security of data transfer is also facing its challenges. If enterprises desire to continue extract value and create opportunities, the foremost priority is to tackle data transfer. Challenges: Large File Transfer ● While the amount of data has skyrocketed, the transfer efficiency is still poor; ● Data types are diverse and traditional transferring methods are difficult to guarantee its integrity; ● Network environment is complex while the cases of data loss and leakage are increasing; ● Cross-regional and long-distance teamwork has increased, but high latency and high packet loss rate have also become prominent. The key to solving the challenges above is to find a first-class data transfer engine. This would eminently support enterprises to build a high-speed, secure, and stable environment for data transfer, which brings an edge to lead in a data-driven development. The Great TCP Bottleneck Transfer protocol is the foundation beneath every data transfer, in which TCP is the most commonly used IP transport layer protocol. Compared to other protocols, TCP is able to provide a more reliable service for establishing connections between specific network systems and applications. Originally developed in the early 1970s when networks were still local and data files were small, TCP served as the basic protocol which enabled data to move efficiently and reliably within the local area network with very small bandwidth. To maintain this reliability, TCP ensures that the application data transmitted in a single TCP connection arrives at the receiver’s application in the same sequence as when it was sent. Therefore, TCP uses an algorithm to establish the connection between the sender and receiver, creating transfer requests in turn, and splitting the data into packets, which are then sent separately through the network without the need for acknowledgement until reaching its definition limit. . The sliding window protocol is used by TCP to define the data buffer. Figure 1 below is a simplified diagram that demonstrates how TCP sends out small packets over the network and how TCP windowing controls how much data can be transmitted without acknowledgement. As the packets are delayed, TCP will then slow down the transfer rate with a smaller window size, which further limits the number of unacknowledged packets allowed. TCP algorithm is proved to be effective when data transfer occurs over a short distance while the network is not congested. However, when the round trip time of packet transfer is inevitably increased by distance, both the performance and efficiency shall be affected. Especially under the scenarios of long-distance, transnational transfer, the transfer of large files and massive small files will expose the drawbacks of TCP protocol: ● Low transfer efficiency, end-to-end transfer requires sequence acknowledgement, the data processing is slow; ● Increase of data loss rate and latency when large files are transmitted; ● Extreme congestion control throttling which results in unnatural throughput loss; ● TCP cannot guarantee its reliability, its file check mechanism is imperfect. In essence, TCP cannot be defined as a reliable transfer in the true sense of the word. Especially under the pressure of data volume and distant transfer, TCP is unable to guarantee the efficiency of transfer and yet it may expose enterprises to data security threats. Raysync – A Brand New Transfer Protocol Raysync’s high-speed transfer protocol is a core transfer technology developed by Shenzhen Yunyu Technology Co., Ltd. based on the UDP transfer protocol. This breakthrough technology does not simply optimize or accelerate data transfer but it takes a leap forward in the transfer technology to completely eliminate the underlying bottleneck while overcoming the limitations of traditional network and hardware. Raysync is able to fully make use of network bandwidth thus provides an ultra-low latency, high speed and end-to-end output service. The transmission rate can be increased by nearly 100 times, achieving over 96% of bandwidth utilization rate while easily adhering to the security, controllability and stability requirements for TB-level large files and massive small files transfer. Transport Layer: A Black Tech that Overthrows the TCP Protocol The TCP transfer protocol does provide a reliable data transfer under ideal conditions, but with its fixed throughput bottleneck, a prominent and serious condition would occur due to high packet loss and latency caused by a long-distance network transfer. Raysync guarantees reliability in the application layer with an innovative method that eliminates drawbacks such as low efficiency in TCP, packet loss, processing errors and unstable transfer rate. To ensure 100% reliability, Raysync adopts the best mechanism that accurately identifies and passes on the actual packet loss condition on the transfer channel. Application Layer: Best Alternative to FTP The FTP transfer protocol has been used for more than 40 years, but it is also a fact that the efficiency of FTP file transfer has been far less than the growth rate of data in the face of today's complex file exchange requirements. FTP is even worse in the file management tasks that enterprises urgently need today. In order to transfer files while maintaining security through FTP, this requires complex scripts, continuous maintenance, and even other applications to assist. All of which may cause time and money losses to enterprises by varying degrees. Basing upon UDP’s high-speed transfer protocol, Raysync breaks through the bottleneck of large file transfer which satisfy enterprises’ needs by building an intelligent transfer platform that processes and integrates massive data at an unprecedented speed. Fast, Secure and Reliable Large File Transfer System With its high-speed transfer protocol, Raysync provides all-around support for enterprises in large file interactions and cross-platform cooperation, achieving standardization within and between enterprises.
