Currently, most large file transfer systems only support single storage, which cannot meet the diverse needs of businesses as storage types become more varied and complex, and business requirements become more complicated. To achieve high flexibility in placing different types of storage on the same server, Raysync adopts virtual path method to uniformly manage different object storage, paths, and network disks, allowing for the addition and deletion of storage and the upload or download of files from storage at any time. Let's take a closer look at how this is achieved. In the server backend, you can add the storage information you want to access, including the storage ID, actual path, account name, and password. With this storage information, the server can connect to the storage and perform operations on its files. Raysync supports local storage, Alibaba Cloud, Amazon, Google Cloud, Azure Blob, and other S3-compatible object storage. Set the logical root path of the server to "/". In the server backend, add a virtual directory for the users, starting with the server's logical root path "/" and then adding the desired path, for example, "/aws". At the same time, bind a storage ID to this virtual path. To uniformly manage various object storages, paths, and cloud drives, it is necessary to create multiple virtual directories. When a user client accesses a virtual directory, the server returns all the virtual paths under the logical root path. For example, it returns "/aws". When the user client continues browsing "/aws", the server receives the request and looks up "/aws" in the virtual path list to get the bound storage ID. Then, it retrieves the storage information by using the storage ID and connects to the storage to traverse the actual path of the storage and obtain the file information under the actual path, such as "/aws/a". At the same time, it looks up all virtual paths under "/aws" in the virtual path list, such as "/aws/virtual path". Finally, it returns the obtained file information and virtual paths to the client. After receiving the browsing results, the user client can begin to manage, add, and delete files, as well as upload and download files between different storage locations.

Data is an advanced commodity, which makes it extremely important to manage data. Without proper tools and strategies, your data may not be as secure as you think. - Use the firewall to protect the company's network security. - Ask your employees to change their passwords every 90 days. - Ensure that the security settings of the company equipment are strengthened. - Implement an annual safety briefing, covering the importance of strong passwords and the importance of locking the keyboard when leaving the desk. The reality is that even if the above security measures are strictly followed, it is still far from enough. If we want to better protect data and establish a stronger security state for the organization, we need multi-layer defense, including regular security training for all employees and updating security policies. Your data may be destroyed by the following practices: 1. Adopt traditional FTP FTP is a common file transfer method. Because of its ease of use, accessibility, and low cost, it is usually the preferred protocol for enterprises or organizations. However, FTP transfer of files cannot guarantee the security of data. Using FTP, users transmit data in clear text through the network, and the exposure risk of data files is high, so anyone can easily access your data. 2. Outdated system and software Software and system updates are released because security vulnerabilities have been found in their code, Java or OpenSSL, and software patches are needed. It is necessary to update the system and software in time to keep your certificate up to date. 3. Opaque network information Monitoring is a key step in controlling the network. If you have multiple systems to manage, it is easier to clearly understand what is happening if you monitor all the data in one place. 4. Unmanaged internet access The explosive development of the Internet has penetrated through the door of enterprises. Apart from the safe working laptops approved by the company, there are also unsafe personal computers, mobile devices, and many other devices. They are connected to your network 24 hours a day, 7 days a week. This uninterrupted access makes it more important to isolate users' folders and their access to the network. Controlling user access will help you distinguish them from important data so that authorized personnel and devices can access it. 5. Failure to provide employees with easy-to-use and suitable tools As employees, there is only one ultimate goal, that is, to finish the work smoothly. Besides, they also want to contribute to the success of the enterprise. When they can't get the tools they need to achieve their goals, they will look for solutions. They download free consumer applications and transmit sensitive data to partners, suppliers, and other external parties through insecure paths. In the short term, it is effective for employees and their daily business objectives, but this approach makes enterprises face various data security vulnerabilities. A reliable MFT solution is a very important defense layer, and MFT platform provides a safe and efficient management system for any organization that must move and protects data to meet business and compliance requirements . Through MFT, you can centrally and globally control the dynamic data of data, and monitor and control all uploading, downloading, and sharing file transfer operations. If you want enterprise data to be transmitted and managed more efficiently and safely, the MFT platform ) is the best solution.

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.
