In the era of big data, the amount of data is exploding. Massive small data has become a very typical data application, such as some picture websites, which may need to process hundreds of millions of picture materials every day. Traditional file systems are difficult to deal with the application scenarios of massive small files efficiently, and there are many problems in the operations of reading, storing and transmitting files. Challenge 1: Low file reading performance and difficulty in file retrieval A large number of concurrent random disk accesses greatly reduce the efficiency of disk operation and delay data access. It is much more difficult to retrieve the corresponding files in the voluminous document database, and the time-consuming of business operation is high, even the files can not be opened. Challenge 2: The amount of data is too large and the storage cost is high The data generated in the production process of an enterprise has a very important business value. When we gather a large number of scattered small files together, we will form a complete asset view and business view. However, due to the immature storage technology and high storage cost, a large amount of data has been discarded before it can bring its value into play. Challenge 3: Massive small files are transferred slowly and the transfer performance is poor Traditional transfer tools can't stand the accumulated data. In addition, due to the influence of transfer distance, network environment, and the size of transfer files, packet loss and delay often occurs, which slows down the business process. Challenge 4: Massive data management is difficult Enterprises continuously generate data increment every day, which makes it difficult to manage massive files. Backing up data, deleting files and sorting data will consume a lot of system resources every day. Raysync solves the data transfer problem of enterprises with its excellent transfer performance. Intelligent optimization technology of disk I/O Any file can achieve the optimal transfer speed with minimal system software overhead. Disk I/O accesses many files randomly with extremely high reading speed.

More efficient and stable transmission performance Raysync transfer protocol can quickly and parallelly transfer multiple data streams through the characteristics of multiple parallel channels, and the transfer speed is 10-100 times higher than FTP. Enterprise-level stability and reliability Breakpoint resume, automatic retransfer and multiple file verification mechanism ensure the integrity and accuracy of massive small file transfer, and the transfer efficiency in ultra-remote and weak network environment is stable and reliable.

Nowadays, the software development of technology and electronics companies requires frequent exchange and cooperation between on-site teams and off-site teams on source code. Due to the influence of the nature of work, there are usually urgent deadlines. Therefore, many teams will choose some tools to help them finish their work quickly and safely. E-mail: is a kind of transfer way people would like to choose, which is very convenient and easy-to-use. However, the size of attachments sent by free email is no more than 30M, and the size of attachments sent by paid email is almost 100M, which can not meet the needs of the data exchange of large projects. Affected by network conditions, transfer distance, etc., the quality of transfer data is compressed, or more seriously, transfer data errors and losses occur. Transfer through the mailbox, without any audit and log records, thus controllable visibility is extremely poor. FTP : Most technology companies build, repair and troubleshoot software through FTP. Because these solutions have almost no rights management and almost no audit and tracking control, IT departments have the least visibility and control over intellectual property rights. Free File Sharing Solutions: Nearly 57% of engineering teams use free file sharing solution, but this solution has security and intellectual property risks. Free applications like Google Cloud are popular among developers because of their ease of use, but they are not designed to protect sensitive company data through functions such as encryption and anti-virus scanning. These tools will also enhance the dispersion of corporate data. Enterprise-level File Transfer Solutions: These enterprise-level file transfer solutions provide a set of more powerful tools to protect and manage software versions, patches, and error logs. Among the 100 senior company managers and IT executives surveyed, 59% have improved their efficiency and security by using enterprise-level file transfer solutions, and centralized control of the exchanged files and contents. Raysync provides enterprises with one-stop efficient and safe file transfer solution. At present, 2W+ enterprises are using Raysync to improve the transfer efficiency and security of enterprises.

The globalization trend of enterprises is becoming more and more obvious, and there are more and more cross-regional and transnational groups. The structure of these groups is characterized by dispersion, which may be headquartered in Beijing, China, and its branches in the United States, Australia, France, and other places. Headquarters needs to synchronize documents such as publicity materials, R&D data, and design manuscripts to all branches. Nowadays, many enterprises try to use FTP to solve the problem of file synchronization. However, there is a problem in using FTP to synchronize enterprise files, that is, enterprises need to arrange manpower to upload files regularly and then arrange others to download them, which wastes manpower and time. Free synchronization tools are also the choice of many companies, but they need certain operation and maintenance capabilities. This type of file synchronization software is prone to errors in the use process, and troubleshooting errors is a labor-consuming and time-consuming project. In addition, this kind of file synchronization software still has certain security risks, and the security of enterprise core data assets should not be underestimated. Under the circumstances, the enterprise needs an easy-to-use, secure, and reliable file synchronization software. Raysync supports two-way file synchronization, it can also detect and manage tasks, and help enterprises easily realize file synchronization function. The key features of Raysync: 1. Supports independent configuration and flexibly grasp file synchronization. You can set file synchronization time, the storage location of synchronized files, the speed limit of synchronous transfer tasks, etc. 2. Enterprise-level security protection to protect the data from leakage. Adopts the financial-grade AES-256 encryption transfer to ensure the safety of data synchronization and guard against data leakage. 3. Stable transfer performance and excellent transfer service. Raysync establishes a reliable data synchronization solution in line with business scenarios of enterprise users. And Raysync provides 7*24-hour uninterrupted service, without monitoring and maintenance by enterprise department personnel.

Only UDP transfer: Only use UDP transfer; 3. Only TCP transfer; 4. System default: UDP transfer is preferred by default, and automatically switch to TCP transfer when the transfer is interrupted. 3. Two-way synchronization mode makes backup more flexible, simple and detailed, which avoids missing files in the backup process and releases the hands of manual copying. Two-way synchronization tasks are carried out in sequence, from client to server upload synchronization, to download server to client download synchronization. 4. Support Raysync download verification to ensure file integrity. When downloading a file, if there is a file with the same name in the download directory, it will be compared with the file on the server, and the server will only send different data for downloading to ensure file integrity. 5. Add "External Http Authentication" for third-party authentication. 6. Add the "Import" button for LDAP authentication. After configuring LDAP/AD domain information in "third-party authentication" of the management console, users can import accounts in the LDAP/AD domain to the Raysync server. 7. Support setting forbidden access path in account home directory. Note the path filling rule: root directory. In addition to the above functions, in view of the special needs of some enterprises, we have also made more support for transferring command lines, which is more convenient for technicians to operate. 8. The transfer command line supports wildcards to upload/download files. For example, if the file starting with D1D052 in the local D:\openssl folder is uploaded to the root directory of the server, then the command line is rayfile-c.exe -a 192.168.186.137 -p 32001 -u test -w Raysync@123 -o upload -d / -s d:/openssl/ -reg ^D1D052.*$ 9. The transfer command line supports moving a single folder or file, such as moving the server \openssl\01 folder to the root directory, then the command line is rayfile-c.exe -a 192.168.186.137 -p 32001 -u test -w Raysync@123 -o move -s /openssl/01 -d /01 The transfer command line supports moving multiple folders or files, such as moving the server \openssl\01 \openssl\02 folder to the root directory, then the command line is rayfile-c.exe -a 192.168.186.137 -p 32001 -u test -w Raysync@123 -o move -s /openssl/01 -s /openssl/02 -d / 10. The transfer command line supports copying a single folder or file, such as copying the server \openssl\01 folder to the root directory, then the command line is rayfile-c.exe -a 192.168.186.137 -p 32001 -u test -w Raysync@123 -o copy -s /openssl/01 -d /01 The transfer command line supports copying multiple folders or files, such as copying the server \openssl\01 \openssl\02 folder to the root directory, then the command line is rayfile-c.exe -a 192.168.186.137 -p 32001 -u test -w Raysync@123 -o copy -s /openssl/01 -s /openssl/02 -d / 11. The transfer command line supports specifying the modification target file name, such as uploading the local D:\openssl\abc.jpg file to the root directory of the server and modifying the abc.jpg as ddd.jpg rayfile-c.exe -a 192.168.186.137 -P 32001 -u test -w Raysync@123 -o upload -s d:/openssl/abc.jpg -d / -t ddd.jpg

In life, various applications such as Internet social networking, audio and video, e-commerce, scientific experiments, and so on are constantly producing tens of millions, hundreds of millions, or even tens of billions of small files. The understanding of massive small files is usually defined by quantification. Files with a size of less than 1MB are called small files, and those with a number of millions or more are called lots of small files . Difficulties in small file transfer The transfer of massive small files is quite different from that of large files. The performance consumption and bottleneck of transferring large files are attributed to bandwidth, while the transfer of massive small files is different. Because the filehandle needs to be opened/closed frequently in the transfer of massive small files, but there is very little content to read and write after the files are opened, the bottleneck of the transfer of massive small files lies in IO performance. Mass small file transfer is a recognized problem in scientific and technological circles, and many technicians have been working hard for it. The following are two solutions given by Raysync, the leading brand of enterprise-level large file transfer. Breakthrough point of massive small file transfer solution 1. I/O read-write optimization technology I/O Input/Output, Raysync utilizes excellent I/O read-write optimization technology , supports up to 5000 read-write capacity per second, provides efficient support for massive small files, and provides high-speed transfer support services for massive files. 2. High-speed Transfer Protocol Raysync has independently developed high-speed transfer protocol, which breaks through the transfer defects of traditional FTP and HTTP and can effectively improve the existing transfer efficiency, reaching more than 100 times the traditional data transfer efficiency, ensuring the high-frequency and extremely fast transfer of massive small file data.

In the Internet age, data transfer and file synchronization are the basic tasks of daily business development of enterprises. And with more and more branches of enterprises, the amount of data is getting larger and larger, and problems such as the loss and leakage of enterprise core data in the process of file transfer and synchronization begin to stand out. How to make the files of each branch transfer quickly and synchronize the files between multiple servers and multiple data centers is a problem that enterprises need to pay attention to. At present, there are many software tools for file transfer and synchronization on the market, but there may be some problems: 1. Unsecure Some software may be constrained by the network environment, the distance of transmission or synchronization, etc. Files are easy to be lost and damaged during transfer or synchronization, and data loss will cause a serious blow to enterprises. 2. Troublesome Many software or tools have a single function and only support one-to-one file data synchronization or transfer application mode. Or the deployment process is complicated, and manual troubleshooting is needed after errors, which wastes time and labor cost. 3. Unreliable When millions of small files are synchronized or transmitted, packet loss may occur, resulting in incomplete and inaccurate transmitted or synchronized files. Raysync is definitely the best assistance of file transfer and file sychronization. First of all, Raysync can guarantee data security, and the bank standard AES-256 encryption ensures the data transfer compliance and security. Secondly, the Raysync self-developed transfer protocol can increase the transfer speed by 100 times in one second. Moreover, the enhanced file synchronization function of Raysync has established a data synchronization solution that meets the business scenarios of enterprise users through the core technologies independently developed such as high-speed engine technology and high-speed transfer protocol technology. Finally, regardless of distance and network conditions, the mechanism of Raysync file breakpoint resume and error automatic retransfer ensures automatic retransfer even if the transfer is interrupted due to unpredictable circumstances in the process of transfer, thus ensuring the integrity and accuracy of transfer results.

The Raysync under Yunyu Technology provides high-performance, stable, and safe data transfer services for IT, film and television, biological genes, manufacturing, and many other industries. At present, 2W+ enterprises adopt the big data transfer scheme provided by Raysync to solve the data interaction problems faced by enterprises. This time, a well-known film and television production company in Shanghai cooperated with the Raysync team. For the film and television production industry, post-editing is the process of re-creation, and its importance is equal to that of pre-shooting. TV series, movies, and so on all need to cut out story clues and plots from massive film and television materials, and also need to add animation, sound effects, flowers, and the other rendering atmosphere to strengthen emotions and enhance the visibility of works. In the post-production process, the flow of video materials runs through the whole business process. In addition to excellent non-editing software and non-editing workstations, enterprises also need to deploy a set of high-efficiency and high-stability transfer software to ensure the transfer quality of massive materials and ensure the successful completion of film production. Project Difficulties The company is headquartered in Shanghai and needs to exchange materials with the team in Japan. Due to the extensive use of CG visual effects, VR shooting, 3D technology, etc., the film and television material files are getting larger and larger, with dozens of GB and hundreds of TB at every turn, and the transfer frequency is high, which requires to transfer almost every day. In addition, the company also has certain requirements for the timeliness of material transfer. Before using Raysync, the company mainly used FTP and other traditional methods to transfer files, which often took two or three days to complete the transfer of a 10GB material, which seriously affected the production progress. 1. A film may be shot in many places, and the changeable shooting location means that the transfer distance of materials is also changeable, including remote transfer, transnational transfer, intercontinental transfer, uploading, downloading, sharing, and other operations. The transfer scene is complex, with a large number and large capacity of transmitted materials, and the material flow is extremely slow. Such a complex transfer scene leads to the extremely unsmooth business process of the film and television production company, and the production progress is seriously lagging behind. 2. As mentioned above, the shooting location is changeable, which also means that the network conditions of the shooting location are uncontrollable. If the materials are transmitted in remote areas with difficult conditions or deserts, the uploading and downloading of videos will sometimes be interrupted due to the poor network environment, and the team sometimes has to arrange special personnel to monitor the data transfer. Even so, there will often be material damage, video mosaic, etc., and the producer's efforts will be burned. Unsafe transfer methods may also lead to the loss and theft of materials during the process of transfer. The content of the film and television industry is paramount, and the confidentiality of the data is very high. The material in the transfer process is maliciously stolen, which may eventually cause the copyright of the film to be infringed. 3. Production teams are scattered all over the world, and the whole team needs close cooperation to ensure the efficient completion of tasks. When the production team is in different places and across countries, the transfer of massive film and television materials becomes a problem. With the popularization of high-definition 4K and 8K, the material capacity of the film and television industry is also increasing. Traditional network transfer methods such as FTP are difficult to ensure the efficiency of large file transfer, which seriously affects the production cycle. This method has been gradually abandoned by film and television organizations. For the needs and pain points of the film and television post-team, Raysync has launched a data transfer solution for the film and television industry. Raysync is based on UDP transfer protocol, which overcomes the bottleneck of traditional data transfer software , provides the highest transfer speed, perfect integration, and control functions for the film and television industry, and brings real high-performance data transfer experience for the film and television industry. The Solutions of Raysync Raysync has a deep insight into the pain points of the film and television industry, helping customers install and deploy the Raysync server in Shanghai. Japanese team members can log in to Raysync through IP address+port number, and easily upload and download film and television materials. Comparison of the transfer data before and after using Raysync: The company used FTP transfer before. After comparison, the transfer speed has been significantly improved after using Raysync, and the upload and download speed has exceeded 90% of FTP; Raysync shortens the transfer time of video materials to the greatest extent. It takes 192 minutes and 39 seconds to transfer 10GB files from Shanghai to Japan by FTP, while it takes only 12 minutes and 42 seconds to transfer by Raysync. Raysync saves the team at least 93% of the transfer time. The Raysync also brings the following conveniences to the film and television team: Complete team and authority control In the traditional FTP solution, the folder structure and permission control are relatively simple, and Raysync provides more detailed, scientific, and complete file and personnel management functions, which meets the multi-line and complex work requirements of the film and television industry. Supports automatic management of the transfer tasks Through Raysync Client, film and television workers can conveniently monitor the transfer of material, uploading and downloading tasks, obtain information such as transfer progress, speed, and status, and can pause, renew and cancel the transfer tasks. Supports the switching of Chinese and English The film and television teams are scattered all over the world, and the Raysync switching function between Chinese and English perfectly overcomes the language barrier of transnational transfer, and the global data transfer is unimpeded. The Features of Raysync Optimize the transfer performance, and transfer video materials efficiently When the network environment is very poor, the transfer is often interrupted due to network failures, sudden power outages, etc. The Raysync breakpoint resume function ensures that the remaining materials can be downloaded from the recording position after the system is started again, with a packet loss rate of 0.00%. Fast file transfer shortens the production cycle Through the optimization of Raysync protocol and automatic compression and packaging, the network bandwidth resources can be utilized and saved to the maximum extent, and the data transfer experience can be provided for enterprise users. The transfer speed of video backhaul can reach more than 100 times that of traditional means, which greatly shortens the time consumption of video material transfer. Enterprise-level security to avoid copyright infringement Raysync has many data encryption schemes, which form an encryption tunnel between the sending and receiving ends of data to ensure that the material files will not be stolen or leaked during the video return process, so as to avoid the infringement of film copyright. Flexible and efficient business management Raysync completely records the complete behavior logs of users such as login, logout, upload, download, and link sharing, and auditors can regularly audit the operation behaviors of members, so as to guard against the occurrence of malicious data leakage.
