[2022] How to Ensure the Safe Transmission of Large File Data?
At present, the amount of file-type data in enterprises has increased sharply, and many enterprises usually use conventional methods such as email, IM tools, FTP, and network disks for file transfer. When the file capacity increases and the network environment deteriorates, the efficiency of file transmission and data exchange is low, and the security is poor. If the file is larger, usually a lower method such as express hard disk is used, which cannot meet the requirements of enterprises to obtain files in time. Seriously affect the overall operating efficiency of the enterprise. Besides, the use of the above-mentioned traditional transfer methods is too decentralized, which is not conducive to centralized management of enterprises. In the era of cloud computing, enterprises currently have more and more service nodes and storage nodes, and data flow requirements based on business processes and hybrid cloud architecture are also increasing. The lack of an effective file transfer management platform is undoubtedly a major pain point. So what transfer methods do companies generally use to transfer large files? How to Ensure the Safe Transmission of Large File Data? 1. CDN Technology CDN: Content Delivery Network . By adding a new network architecture to the existing network, it is mainly composed of two parts, divided into two parts: the center and the edge. The center refers to the CDN network management center and the DNS redirection resolution center, which is responsible for global load balancing, and the equipment system is installed in the management central computer room, edge mainly refers to remote nodes, the carrier of CDN distribution, mainly composed of cache and load balancer. Choose to publish the content of the site to the "edge" of the network closest to the user, so that the user can obtain the desired content nearby, thereby improving the response speed of the user to the site to a certain extent. The data requirements of CDN are only independent documents or "independently replaceable" document parts. 2. Transmission Technology Based on FTP Protocol FTP ) is the abbreviation of the File Transfer Protocol. FTP allows files to be shared between hosts and is used to control the two-way transmission of files on the Internet. It is a C/S system. FTP uses different port numbers to transfer different content, and different TCP connections are established. First, use TCP to generate a virtual connection for transferring control information, and then generate another connection for data transmission. Combined with the FTP protocol, it can use file or file , file verification, and other technologies, and can also transfer large files. FTP transfer software such as also can manage users, block or filter designated IP addresses, port, control user upload and download speed, detailed transmission history, and log, and can also carry out an encrypted transmission of data. It has the advantage of ensuring transmission security and protecting personal privacy. 3. Transfer Files Based on Middleware Use MQ, MT, and other middleware to transfer files, with data compression, large file transfer, and breakpoint resumable transfer. The transfer of large files uses BlobMessage, which uses fileserver to transfer efficient processing. Message middleware technology has two core functions: asynchronous and decoupling. These two core functions improve the working efficiency of the application system as a whole, enhance the usability, stability, and scalability of the system, and can realize the safe and reliable transmission of large files. 4. IM Instant Messaging Technology Most of the Instant Messenger technology is based on TCP/IP and UDP for communication, while TCP/IP and UDP are communication transmission protocols based on the lower-level IP protocol. The former is through the form of a data stream, after dividing and packaging the transmitted large file data, through the virtual-circuit connection established between the machines, a continuous, two-way transmission protocol that strictly guarantees the correctness of the data is carried out, mainly Reliable transmission is achieved through mechanisms such as checksum sequence number, confirmation response, time-out retransmission, connection management, and window sliding. The latter is a connectionless transport layer protocol in the OSI reference model, which is mainly used for data that does not require data In the transmission of packets arriving in sequence, the checking and sorting of the packet transmission sequence is completed by the application layer. It provides simple and unreliable transaction-oriented transmission services. Because of its fewer control mechanisms, the delay in data transmission is small and the transmission efficiency is high. IM technology mainly combines the advantages of the two to highlight the characteristics of immediacy and accuracy of transmission, but there are still certain technical difficulties in the application of large file transmission. Through the comparative analysis of the above transmission methods and market demand, the advantages of transmission software are obtained: 1) Transmission efficiency and throughput optimization; 2) The maximum transmission speed can be set; 3) The transmission performance is proportional to the bandwidth and has nothing to do with the transmission distance, and the packet loss rate has little effect; 4) Bandwidth management function; 5) Fair sharing strategy: automatically make full use of available bandwidth resources; 6) High priority strategy: real-time dynamic allocation of priority and bandwidth; 7) Realize user and terminal authentication in a safe way; 8) Application of encryption algorithm, suitable for encryption during transmission and landing encryption; 9) Scalable management, monitoring, and control; 10) View transmission progress, performance, and bandwidth usage in real-time; 11) Detailed transmission history and log. Based on the problems and status quo that most companies are facing to transfer large files, and based on the analysis of the characteristics of the original mainstream transmission technology, the fundamental to ensure the secure transmission of large file data lies in the development of the transmission software that has the advantages described in the third party. At the same time, it can solve the current technical difficulties in transferring large files.

[2022] 5 Easy Ways to Transfer Files Between Computers
You might think that simple operations are as simple as on a home network. Unfortunately, this is not the case. 5 Easy Ways to Transfer Files Between Computers On the company network, the company’s IT department usually creates a network shared drive, and anyone connected to the computer can place and exchange files over the network. On your home network, you don’t have an IT department that can do this for you. You don’t need to worry, because there are many easy ways to do this. 1. Proximity sharing: Share files in Windows 10 Before April 2018, to share files through your home network, you need to try to set up a so-called "homegroup." This is a group of computers connected to the common network group on the home network. It allows file sharing, but due to security software or network firewalls, its settings are very complicated and it does not always work properly. Microsoft is very grateful that it introduced other simpler ways to share large files site over the network . Sharing on the local network involves a feature called nearby sharing. You need to enable "Nearby Sharing" on all computers you want to share files with. To do this, do the following: 1. Open the settings and click System. Choose a shared experience. Scroll down and find nearby shares. Switch the switch to on. 2. Set the drop-down menu below it to everyone nearby. 3. After enabling "Nearby Sharing" on all Windows 10 computers on the network, you can start sharing files with them. To do this, open FileExplorer, right-click on the share you want to share and select Share. You will now see all computers with nearby sharing enabled under the Find more people section. When you select the remote computer system, a notification will appear that there is an incoming file on another computer. Choose Save and Open or Save to start the file transfer. 2. Transfer files via email Another method of transferring files between computers, not only through the local network but also through the Internet, is to share via e-mail. The process is similar to "sharing nearby." Just right-click the file you want to transfer and select share. At the top of the "Share" window, you will see the email contacts you want to select. 1. Click Find more people to open your email contacts, and then select from your contact list. 2. This will open an email compose page. You can edit the email or click Send to send the file. 3. If you have not yet used the email service of your choice, you may need to grant Windows permission to send an email on your behalf. 4. When receiving a file via email, you can receive it on any device . 3. Transfer files via the cloud The third way to transfer files from a Windows 10 PC to other devices is through the cloud. You can achieve this by sharing files to any Windows application that supports services such as OneDrive or Google Drive. 1. Just right-click the file you want to transfer and select share. 2. At the bottom of the "Share" window, you will see a list of Windows applications to choose from. At least one of them should be OneDrive. 3. After opening the application, just click the "Add" button to add the file to your OneDrive cloud account. 4. The file will be uploaded to your OneDrive account. Once you are done, you can open the OneDrive app on another computer and upload it there. 5. On another computer, open the OneDrive app, right-click the file, and select Download. This will complete the file transfer to another computer on the network . 4. Use FTP client/server software Another excellent solution is to use FTP as a fast file transfer via LAN. By running an FTP server on one computer, you can use the FTP client software on another computer to connect to the server through port 21. The problem with many FTP server applications is that their setup and configuration are complex. Fortunately, there are several quick and easy FTP-server applications. Is a free application Baby FTP is one of them. With BabyFTP, you only need to install the application and it will start a simple anonymous FTP server on the original computer. In "Settings", you can configure the transfer between folders and files, the operations to be allowed , and whether the remote client can modify these operations. Start the BabyFTP server, if everything is normal, you should see "FTPServer started on port 21". Now, on another computer, you can use any FTP client to open a connection with that remote computer using its IP address and port 21. This application does not require an ID or password because it only uses an anonymous connection . After connecting, you will see the remote directory that has been set up at the remote site location. You can right-click the file there to upload it to the local computer, or right-click the file on the local computer to transfer it to the remote computer. 5. Transfer files between Windows 10/11 computers Surprisingly, without third-party software and other solutions, simple operations like transferring files between computers will be very difficult. Thankfully, there are many options to make the process simple and easy. Raysync high-speed large file transfer solution is committed to meeting the needs of large data transfer within the enterprise or with external partners, providing efficient and controllable accelerated transmission of large files, ultra-long-distance, transnational network data transmission, secure file asset distribution, file management.

SendGB SendGB is one of the easiest ways to transfer files to others while protecting your privacy. It allows you to send files up to 5GB without registration. You can also choose how long the file is stored on the server. If you want, you can choose to add a message. The upload box has a self-destruct option. If you add the recipient's email address, the file will self-destruct after each recipient downloads it. If you simply share it as a link, it will disappear after the first download. When uploading a file, you can choose the time to store it on the SendGB server. For files with a maximum capacity of 250GB, you can store them for 90 days for free. Files larger than this size will be automatically deleted after 7 days. However, you can use SendGB Extend to store them for a longer period of time. SendGB Extend is a paid service that allows the file to be used for up to one year at a price of two euros. 3. KwiqFlick Although most online file transfer tools are eager to delete files from their servers to protect privacy, KwiqFlick wants to keep it open. It allows you to choose when to delete files. Users need to register to upload and send files, but email recipients can download files without an account. You can send files up to 2GB. These files will be stored in your account until you delete them, which makes it easier to resend frequently used files. KwiqFlick can be a good temporary file storage space for projects you are collaborating with. You can also increase storage space and file upload size by asking others to sign up for the service. Finally, it's a bit like cloud storage services like Dropbox or Google Drive. But you will not waste time on file and folder synchronization or similar operations. 4.TransferXL If you want to share photo albums for a few days, TransferXL is a good choice. It can transfer up to 5GB, and the images will be stored for a week. TransferXL also creates thumbnails for all images, which is a big attraction. Then, the recipient can preview the file and choose what to save. After all, not everyone wants to get all images. But for those who do, there is a convenient option to download multiple files as one zip file. Those who value privacy can choose to store their data on the server. You can also choose to encrypt files according to your needs. In other words, if you are just sharing an album that you want to publish on social networks, neither of these two are particularly important. Overall, this is a great way to share albums for a few days without taking up space on your Dropbox or Google Drive. 5. Cend Cend is an alternative to the popular FilePizza, a peer-to-peer file-sharing web application that runs entirely in your browser. Think of it as a torrent, but there is no torrent client. No server is involved, it is transmitted directly from your computer to your friends. The advantage of this is that for large file transfers, you can start immediately. You don’t have to upload it to the server first while your friends are waiting. Only when you are done can your friends start downloading after sharing the link. This is instant, which is great when you are dealing with gigabytes of data. Cend does not require registration. It will automatically generate a password and link, and the recipient needs to use the password and link to start the transmission. You need to keep the browser tab open during the entire transfer process, as do your friends. Yes, there is no file size limit 6.Sharedrop Apple's AirDrop allows you to share files between different Apple devices connected to the same Wi-Fi network. Share drop hopes to make this happen between any phones, tablets, or computers that don't have anything installed. Launch Sharedrop in the browser tabs of two or more devices. Each device or user has its own nickname and avatar. Drag and drop the file onto the logo of any avatar to send the file to the device. Of course, the recipient must accept it. The entire technology can be operated via WebRTC, so there is no need to download any content. If you lose your Internet connection while transferring files, Sharedrop will continue to transfer. Sending files via Wi-Fi is also the fastest wireless method. 7. File-Transfer Time Calculator With so many options, which file transfer service should you use? Well, one way to find the answer is to calculate based on the fastest speed. The file transfer time calculator will calculate how long it will take to upload or download a file. Put the file size in the first column and the internet speed in the second column. It also allows you to add overhead percentages for other Internet tasks that must run at the same time. The calculator also includes options for different wired connections, such as USB, wired LAN, Wi-Fi, SATA, etc. When you are dealing with gigabytes or terabytes of data, you may want to check whether the actual interaction with the recipient is faster and transmitted via cable.
What is Secure File Transfer?
The transfer of sensitive and often proprietary files from one person or organization to another has become a complex aspect of today's business world. This complexity comes not only from the size and number of files that need to be shared but also from the need to protect them all the time from the sender to the receiver. Although there are excellent solutions for secure file transfers, many IT departments still rely on outdated options, including FTP, PC tools , or old scripts. These measures simply cannot solve the problem of improving overall efficiency, ensuring company data security, or demonstrating compliance with industry requirements for how to protect and exchange information. With this in mind, let's take a look at how secure file transfer works. Define secure file transfer At a higher level, secure file transfer is just one way to protect file movement. Through scripts, PC tools, or hosted file transfer solutions, secure file transfers can usually encrypt information during transfer and at rest, and create audit records of all file transfer activities, which is very suitable for production to show compliance with PCI DSS, GDPR, SOX, HIPAA, NIST, and other requirements. There are many types of solutions available for secure file transfer. However, if you are looking for a powerful secure file transfer platform that includes additional features such as automation, the ability to send large amounts of files, and user-to-user collaboration tools, then Managed File Transfer is the best choice on the market. More MFT definitions Main functions of managed file transfer software Batch file transfer and temporary file sharing Static and dynamic file encryption Automation replaces error-prone manual activities Audit trail and PDF report prove compliance Secure collaboration tool for internal file exchange This sounds very appealing and has many benefits for ordinary organizations, right? So why did the IT team give up on implementing hosted file transfer software? Where is the company wrong? In today's organizations, there is a trade-off between security and convenience. According to a survey by HelpSystems in 2018, more than 65% of IT and security teams struggle to balance network security control and business efficiency, while 46% struggle with insufficient network security skills and staffing. Tools such as intuitive secure file transfer solutions can greatly meet the needs of enterprises for efficiency and security, especially in data encryption. But sometimes, the path of least resistance presents obvious risks while also tempting. When transferring files from outside to trading partners or customers, there may be a variety of malicious technologies at work in your organization. This decentralized approach makes it impossible to securely manage file transfers and protect data. The following are common methods for organizations to exchange files without a highly secure hosted file transfer solution: Developers usually create scripts to handle one-time file sharing requirements, such as reports that must be generated and sent to trading partners every week. However, when the server IP or login credentials change, management becomes very complicated, especially for time-critical resources. The password embedded in the script is also vulnerable to attack and abuse. Besides, the scripts are too simple, that is, if the scripts fail the first time, they cannot be retried. Likewise, they lack notification functions. Scripts are just patches to solve larger problems, making the centralized file-sharing method included in the hosted file transfer solution more effective. For decades, FTP was the de facto standard for sending files. However, it cannot see who is accessing the file, and it lacks the overall security features needed to protect the transfer of sensitive files. It also stores the user's credentials to log in in "clear text", making intrusions easy. PC tools and free software introduce one of the most common sources of data leakage: human error. Perhaps the file contains sensitive information that the user forgot to encrypt. Or the file is sent to the wrong person and cannot be called. Maybe someone manually transfers the file unexpectedly, and no one knows the steps to correctly send the file to the correct recipient. All these possibilities put sensitive data at risk. Likewise, insecure email and cloud services make it difficult to prevent sensitive information from leaving your organization. Features of secure or managed file transfer solutions You will find various features on the market today, but the following are the main considerations when choosing a secure or hosted file transfer solution: Ease of use: The easier the software is to navigate, the better the adoption for administrators and end-users. If the solution is puzzling, people will revert to old tools and habits, and your new purchase will become a shelf commodity. Ensure that administrators or other key users can easily set up and execute file transfer workflows. Also verify whether the solution can seamlessly interact with other systems, applications, and APIs. This will help centralize work. Does secure file transfer meet your requirements? Security and compliance: The product must be able to support the latest security protocols and algorithms so that you can consider all customers and trading partners. It needs to enable you to meet the details of any regulations that need to be resolved. It should have centralized control that can only be accessed by authorized administrators. This means that only one audit trail can show file activity, user activity, and all system changes. Error handling and peace of mind: a powerful secure file transfer system can highlight any abnormalities of the expected task, so they can be resolved quickly. This is the only way to protect the organization's relationship with customers and partners. As you know, secure file transfer is an efficient way to protect your company’s valuable and sensitive information while increasing employee productivity. When the above features are combined with automatic file transfer workflows and collaboration-enabled features, hosted file transfers are an excellent choice for meeting secure file transfer requirements. Raysync high-speed large file transfer solution is dedicated to meeting the data transfer needs of enterprises or external partners, providing efficient and controllable accelerated transfer of large files, ultra-long distance, transnational network data transfer, safe distribution of file assets, file management and organizational authority management. Support local deployment and cloud services, and provides enterprises with safe, stable, efficient and convenient large file interactive technical support and services.
What is File Transfer Service in 2022?
When using FTP to transfer files, there is no need to perform complex conversions on files, so FTP is much faster than any other method to exchange data. The combination of Internet and FTP means that every networked computer has a huge backup file library, which is an advantage that a single computer cannot match. However, this also causes a shortcoming of FTP, that is, users cannot understand the contents of the file before the file is "downloaded" to the local. The so-called download is to transfer software, text, pictures, images, and sound information on the remote host to the local hard disk. File transfer service is a real-time online service. When performing file transfer services, you must first log in to the other party's computer. After logging in, you can only perform file query and file transfer-related operations. Use FTP to transfer many types of files, such as text files, image files, sound files, data compression files, etc. When evaluating secure file transfer applications, companies should pay attention to the following important issues: security, architecture, features, and ease of use, management, reporting, licensing agreements, and total cost of ownership. Since data leaving the boundaries of the company may contain sensitive or confidential information, locking down this data and ensuring that only approved recipients can receive the information should be a key criterion. Security evaluation involves examining the product from multiple aspects, including the overall architecture, data storage and protection, user authentication, permissions and roles, administrator-definable policies, and even how an application gets the underlying platform and current status. There is security configuration support. Besides, it is also necessary to test whether it can defend against common vulnerabilities, such as SQL injection and cross-site scripting attacks are very important for any public-facing application. The overall architecture and design method of the solution can reflect the manufacturer's plans and ideas in the product to a large extent. Good product developers build products for today’s needs, but they must anticipate tomorrow’s needs. When reviewing any secure file transfer architecture, companies should pay attention to how vendors deal with encryption, flexibility, upgradeability, support for large files, network outages, and policies. In addition, it is also important to consider issues such as integration and expansion of existing applications, customizability, performance, user and system management, product platform support, and programming interfaces. In addition, it is necessary to consider whether the application design is logical, whether the components can be well matched, and whether the secure file transfer application adapts to the existing infrastructure. A well-designed user interface is essential to the success and effective use of any technology. The more friendly the interface of a system, the more likely it is to be adopted. Important elements of the secure transfer application interface include whether the screen is tidy, whether the control is intuitive, whether the text is clearly expressed, and whether the appearance and feel are generally consistent. These elements directly affect the adoption of the transfer scheme, and the easiest to use tool will most likely be accepted by the end-user. Two important aspects are involved when managing a secure file transfer scheme: user management and system configuration. Basic user management rules include: minimizing copies of information , using existing identity and access management databases, and making automated systems run as much as possible without continuous IT intervention. Flexible system configuration and settings can enable companies to more closely match and support existing strategies and processes. After deploying a secure file transfer program, the report becomes an important tool for understanding the utilization of the program and audit support. Compliance requirements may require the generation of reports to meet legal regulations or to meet internal usage guidelines and company supervision. The ability to monitor user activity and in-depth analysis of real activity can help identify or correct non-compliant activities and processes, and meet corporate file sharing restrictions. License agreement and total cost of ownership Companies implementing secure file transfer tools can enable users to send sensitive files and data through secure channels in new ways. Although this function may meet the needs of some individuals or individual departments at the beginning, the scale of its implementation tends to increase. Firewall rules: strictly limit the scope of the file transfer Restricting the scope of file transfer channels is the basic rule used by firewalls, but once you have designated one or several systems as your sFTP hub, make sure of the following issues: Only the sFTP traffic system permitted by the rules can pass through the firewall; only the remote approved system can be used as the source or destination of sFTP packets; SFTP is the only encrypted traffic that passes through the firewall of these systems. Although SFTP traffic is encrypted, it is an opaque management tool, so you need to make sure that it is the only opaque traffic that flows to and from these systems. Most organizations have no need to communicate with external entities or do a list of rapid growth or system changes for the secure transfer of bulk files. So if you really need frequent or rapid changes, you may need to use some security coordination tools to adjust the necessary rules to the source or destination. Use host tools Considering the rest of your environment, you need to carefully consider host-based mitigation methods. Security and system management vendors have changed in recent years, introducing high-speed analysis into their host-based system monitoring tools. In particular, some have been found to be used both in normal behavior patterns, such as operating system service calls , as well as abnormal situations on the system that have the least impact on performance. Running host-based abnormal behavior detection can reduce the movement of sensitive data into unauthorized channels. Don’t pay attention to content, pay attention to network behavior In addition to the host, network behavior analysis can also find changes in data streams, even the content of encrypted data streams that some tools cannot see. Since they can see the number, destination, and duration of data flows out of the system, these tools can help monitor data leakage in the process. It is difficult to effectively use this system, especially when identifying the "normal" early stages of traffic; such as intrusion detection systems, data leakage prevention systems, and network behavior analysis tools are all prone to "false positives", which reminds us to judge which Is abnormal behavior. Security personnel needs to spend extra time to learn these systems or use some kind of professional service to deal with this time-consuming work. The security team also needs to determine and follow the security process, continuously improve the early warning and response rules based on the alert assessment, and gradually reduce the number of false clicks. Be your own middleman The most extreme way to prevent leaks is to open all encrypted traffic that flows through the relevant part of the network of equipment capacity capable of performing these middleman functions. The encrypted traffic in these devices faces internally and ends at the system, while the channel faces externally and ends at the other end of the data flow. The channel will encrypt and decrypt it. It can then use deep packet inspection tools to analyze the content sensitivity and mark it as suspicious, and then completely block or allow it to pass. If allowed, the traffic will be re-encrypted and sent to the destination. This is a very computationally intensive task and very expensive. However, by checking all incoming and outgoing encrypted traffic, the risk of data being hidden in the encrypted data stream can be significantly reduced. This can introduce their own reasonable risks, so the scope of encrypted data stream capture needs to be carefully defined and discussed with enterprise risk managers. If this range needs to be extended to cover user endpoint devices and non-sFTP encrypted streams, then users need to know that their encrypted traffic may be exposed to IT personnel.

Unaffected by traditional file transfer methods , minimize the transfer delay and packet loss rate of large files and big data, make full use of network bandwidth resources, and realize various business systems and various operating system platforms data file collaboration to solve the problem of large file transfer and large data islands.
[2022] How to Solve Large File Transfer Problem?
Large file transfers are often a huge challenge for organizations, especially when data needs to be transferred across long distances and scattered servers in a short period of time. If you do not have the right toolset to try to transfer large files, it means that the massive file transfer process may face risks of data security, high latency, TCP/IP transmission limitations, data transmission failure, data loss, and inefficient use of bandwidth. With a fast file transfer solution equipped to handle large files, you will not face the lack of SLA and critical deadlines, and you don't have to spend time worrying about when large files will arrive at their destination, just as you need. You are forced to carry or transport a hard copy of the data. The problems solved by fast file transfer solutions include low bandwidth utilization, excessively long delays causing file transfer bottlenecks, slow, inaccurate and inefficient file transfer processes, large file transfers, long-distance file transfers, including large data set transfers. When evaluating vendors and fast file transfer solutions, it is important to understand the common data transfer challenges caused by data transfer delays and the help of fast file transfer solutions. Bandwidth is the amount of data that can be transmitted in a certain period of time. Bandwidth utilization is the amount of bandwidth used compared to the total bandwidth available. Always use all the bandwidth you pay for. Your company has purchased a certain amount of bandwidth from your service provider. How much bandwidth you pay depends on the maximum bandwidth you expect to use. However, only when there are occasional peaks do you actually use all the bandwidth you paid for. Latency is the time it takes for the file to be transferred across the network. Delay has negative connotations, such as "the delay of the network is slowing down my transmission speed". Latency + bandwidth defines the speed and capacity of the network. File transfer Protocol/Internet Protocol, the most commonly used protocol for Internet communication, TCP is optimized for accurate delivery rather than timely delivery. Therefore, TCP sometimes causes long delays when waiting for retransmission of out-of-order messages or lost messages. It is not suitable for real-time applications such as VOIP. The data is divided into several parts and sent as individual "data packets", and then these data packets are recombined at the receiving end. The extra data is added in the form of a "header" that tells the receiving end how to reassemble the data packet and ensure that everything sent is actually received. This will split the file and reassemble the file, sending confirmations back and forth to ensure that there are no errors that will slow down the transmission . Raysync is a secure and high-speed file transfer solution. Providing a file transfer alternative to existing FTP servers.
