File synchronization is the process of ensuring that computer files in two or more locations are updated through certain rules. In one-way file synchronization, updated files are copied from a "source" location to one or more "destination" locations, but no files are copied back to the source location. In bidirectional file synchronization, updated files are copied in both directions, usually to keep the two locations the same as each other. Nowadays, general file synchronization usually refers to two-way file synchronization. General file synchronization systems have the following functions: encryption to ensure security, especially when synchronizing over the Internet, compressing any data sent over the network. Conflict detection modifies the location of files on two sources, not on one source. Undetected conflicts may cause a copy of the file to be overwritten with the latest version, resulting in data loss. For conflict detection, synchronization software needs to keep the database of synchronization files. Distributed conflict detection can copy the data or application files in use or the database files locked exclusively through version vector, and "open file support" can ensure data integrity; Especially support the use of intermediate storage devices to synchronize two computers. Most synchronization programs can be used in this way, but providing specific support for this can reduce the amount of data stored on the device; Ability to preview any changes before making them; Ability to view differences in a single file; Backup between operating systems and transmission between network computers; At present, more and more people have multiple intelligent terminal devices, which greatly facilitates people's work and life. The popularity of intelligent terminal equipment not only brings convenience to people but also brings new challenges to people's file management. How to ensure data consistency among multiple devices and how to synchronize files efficiently has become the focus of attention. When we return home and want to deal with some working documents, file synchronization can play a great role. At home, we can deal with working things in a timely manner as in the company. Syncthing: The biggest feature is that P2P distributed technology similar to Resilio Sync is adopted, and multiple devices can synchronize files with each other in real time without a central server. The function is very close to Resilio Sync/BT Sync. However, it seems inappropriate to say that it is a server software or cloud storage service application for building network disk. Compared with server tools such as Seafile and NextCloud, Syncthing is actually more like a file/folder synchronization tool. Dropbox: It is a free online file synchronization tool and an online storage service operated by Dropbox. It realizes file synchronization on the Internet through cloud computing, and users can store and share files and folders. Dropbox provides free and fee-based services, and its fee-based services include Dropbox Pro and Dropbox for Business. There are client software under different operating systems and web clients. For freelancers and independent employees, it can reduce the time spent on file backup and storage, and the version backtracking function provides unparalleled convenience for some misoperation or version comparison. So that workers can focus more on their work than on their documents. For enterprises, file synchronization is more convenient for managers to understand and control the whole project schedule.

File Transfer Protocol provides a simple way for users to send files and information ad hoc from one location to another. FTP provides a medium for establishing communication between computers for file transfer. Although it is still a widely used and well-known file transfer method, people have many misconceptions about FTP. The following are some of the most common misconceptions: Misconception 1: FTP encrypts data as it’s transferred. FTP doesn't encrypted the data in the process of transferring. When FTP is used, all transmissions are transmitted in clear text, which means that if the transmission is intercepted, the data can be easily obtained. Data leakage occurs when users send sensitive data through unsafe sites or anonymous FTP sites. Using FTP to transfer business data means sacrificing data security. In addition, enterprises or organizations install FTP servers for some reason, but they usually forget the existence of FTP, do not update it, and have little supervision over the data stored on it. Misconception 2: All that matters is getting data from point A to point B. In addition to ensuring that files go from one location to another, you need to work hard to prove compliance with data protection regulations. FTP is developed only for transferring files, and does not provide any functions to support security and compliance requirements. If you have any sensitive or regulated data to transmit, choosing FTP will expose these important data to danger. Misconception 3: Homegrown FTP is good enough If you use the local FTP system, you may encounter problems and face many risks. Data silos may pose various challenges to employees who need timely access to data to make data-driven business decisions. You may also find that you spend more time logging in to various systems and platforms, troubleshooting or performing other related maintenance tasks. Using distributed file transfer systems also makes it more difficult to manage compliance. IT is time-consuming and error-prone to audit various applications and systems without a comprehensive understanding of IT systems. From FTP to MFT Managed file transfer technologies provide multi-layered security and compliance supporting capabilities, far beyond the more basic file transfer mechanisms like FTP. MFT technology’s features include in-depth reporting , global visibility into your data at all times, end-to-end security with encryption of data in transit and at rest, performance metrics/monitoring to meet stringent SLAs and compliance mandates, and the automation of file transfer-related processes. If you are looking for a stable and secure file transfer software, Raysync is definitely your best choice!

In recent years, data leakage and privacy incidents have become more and more common and costly. A study by Risk Based Security found that data leakage increased by more than 54% compared with the same period of last year. Meanwhile, IBM's annual data leakage cost report found that the average total cost of data leakage was close to 4 million dollars. With more and more information interaction involved in enterprise business, these privacy-related user data are always targeted by criminals in the transfer process, which also makes the enterprises that collect, store and use a large amount of user data a headache, and have to spend a lot of energy to find a safe and efficient solution for enterprise large file transfer. Below are four ways Raysync would help enhance your security posture, facilitate compliance, and help you improve the file transfer efficiency: Scenario 1: You’re Still Using The Traditional File Transfer Protocol, Like FTP Quite a few of our customers come to us using FTP or a homegrown file transfer solution. They’ve complained about the old system being unreliable, inflexible, and potentially insecure. They often find that their transfers tend to fail when network latency increases. Although FTP or the other solutions were good at a point in time, they have become too simple and ill-equipped to handle the data exchange needs of the modern enterprise. Is that mean enterprise should abandon the old way and choose a new solution? Of course not, for many enterprises, FTP and some other old file transfer systems are essential in the business, which can't be replaced in a short time. Under this circumstance, Raysync has provided you various solutions, with Raysync FTP acceleration, and other large file transfer solutions like SDK application integration, it's neven been so easier to transfer your large file securely and quickly. Scenario 2: You’re at Risk of Leaking of Supply Chian The IT Security Economics report released by Kaspersky in 2019 shows that the data leakage incidents involving third-party suppliers in large enterprises and small and medium-sized enterprises are 43% and 38% respectively. According to One Identity's survey, 94% of organizations grant third parties access to their networks, while 72% of organizations grant privileged access. However, only 22% were convinced that the third party did not access unauthorized information, while 18% reported that the third party's access caused violations. It is a method to guarantee enterprise information security for suppliers to sign security policy agreement or service level agreement. Agreements or contracts can protect security to a certain extent, but for enterprises, the most important thing is to choose a reliable and secure third-party file transfer service provider. A secure enterprise-level large file transfer solution is the foundation to ensure reliable network, information security, and stable transfer. Scenario 3: You're Underestimating the Network Security Priorities In news reports, we often see data leakage incidents of large enterprises, but the fact is that small and medium-sized enterprises are most vulnerable to network attacks. Unfortunately, many SME executives are the least likely to give priority to network security plans. According to a study conducted by Keep Security, 66% of small and medium-sized enterprises do not believe that it will cause data leakage. Dramatically, the evidence of the Ponemon Institute shows that 67% of small and medium-sized enterprises suffered serious cyberattacks last year. Facing the same network environment, threats will not only target large enterprises. When small and medium-sized enterprises choose large file solutions, the assessment of safety factor should not be ignored. The TLS+AES-256 encryption algorithm is an enterprise-level file transfer expert who can achieve the international top financial security. The design of multiple versions of Raysync Transmission can well meet the file transfer needs of small and medium-sized enterprises or large enterprises. Scenario 4: You Have Lost Visibility into the Data on Your Network and Who Has Access to It Maintaining visibility and control of your organization’s network can prevent expensive security breaches. You must know what data you have on your network, and you must be diligent about who can access that data. Poor visibility can lead to proprietary data falling into the wrong hands or breaking compliance regulations. That can damage your reputation and costs literally millions of dollars in fines and litigation. What is the charm of the large file transfer solution chosen by 2W+ enterprises! Join in Raysync to start your file transfer journey.

Many people are still using more traditional methods to transfer files, such as mail, FTP, WeChat, etc. These methods make it easier for individuals to transfer small files. However, in enterprise applications, there will be various problems in the process of the transfer due to the excessive number and volume of files. Film, television, meteorology, biology, oil and natural gas, and other industries need to transfer a vast amount of data within the enterprise or between internal and external partners. Traditional methods are difficult to solve the problem of data transfer. Which software is the best to transfer 100GB of large files at maximum speed? This has become a problem that many industries pay close attention to. The most important requirements in large file transfer of enterprises are security and efficiency. High Efficiency, that is, to make the full use of the network bandwidth resources and to quickly send data to the destination; Security means protecting the data from leakage, damage, and breakage during transfer. Instant communication tools usually do not have the function like the breakpoint resume, once the transfer process is interrupted, all the files need to be transferred from the beginning, which greatly wastes time, bandwidth and manpower. Another reason that causing low-speed file transfer is the transfer protocol, based on the TCP protocol, the traditional transfer methods' transfer efficiency is low when packet loss happens during transfer. Besides, because of the openness of the traditional protocol, the data leakage is usually common in the process of the file transfer. A professional file transfer solution has perfectly solved the difficulty faced by file transfer. Those solutions have their own designed transfer protocol, greatly utilize the available network bandwidth, and solve the problem of packet loss. Meanwhile, there is also an encryption mechanism for data transmission to ensure data security. How to transfer the large files of 100GB at maximum speed? The professional transfer software like Raysync adopts the self-developed transfer protocol, fully utilizes the network bandwidth, it could transfer the large file at maximum with minimal packet loss. With the AES-256 security protection, your data will be transferred fast and securely with Raysync Transmission.

On a normal day at work, sending files is probably as common as your morning cup of coffee. A large part of your day may involve exchanging files like reports or designs with clients, employees, and vendors. But if the size of the file is too large, for those traditional file transfer tools like email and file storage applications, it is impossible to transfer it quickly. You would need a solution that can handle large file sizes and not interrupt your routine. The stability of file transfer is fundamentally based on excellent transfer performance. Raysync Transmission is based on UDP transfer performance, breaking through the transfer defects of traditional FTP and HTTP. The self-developed transfer engine supports 10,000 megabytes of bandwidth. The multi-dimensional transfer mode meets the high-speed transfer requirement of TB-level large files.

FTP traditionally has been the most common way to exchange files over the internet for years. FTP-FTPS-SFTP seems to be an update of FTP, but is this real? Or as everyone has said, that the progress of new technologies has made FTP obsolete? If you are currently using FTP and looking for an alternative that provides visibility, control, and automation while improving security and manageability – this article takes a deep dive into what FTP is, its attributes and gives you the info you need to consider replacing FTP with a better file transfer solution. File Transfer Protocol is a method of transferring data files from one computer to another over a network. As one of the original programs for accessing the information on the internet, it was developed in 1971 as part of the U.S. Department of Defense’s ARPANET protocols and thus predates both the TCP and Internet Protocol . FTPS and SFTP FTPS and SFTP are two separate protocols used as secure alternatives to traditional FTP. Often mistaken for each other, these are two very distinct protocols with different pros and cons: FTPS  is an extension to the commonly used File Transfer Protocol that adds support for the Transport Layer Security and the Secure Sockets Layer cryptographic protocols. SFTP  is a secure alternative to FTP and is often mistakenly used to specify some kind of Secure FTP, by which people most often mean FTPS. SFTP is a binary protocol in which all commands are packed to binary messages and sent to the server, which replies with binary reply packets. Why Replace FTP? Since FTP is typically used to solve a single problem or meet a specific application requirement, it usually results in multiple discrete deployments with no central management and control — leading to many business challenges for enterprises, which is not visible at the surface. Here are some driving factors for replacing FTP: Security There are a number of risks associated with using native FTP such as having FTP port open in firewalls and a lack of encryption. Exchanging information without the necessary security features could lead organizations to face massive fines in the event of a breach or a public relations disaster. Lack of Visibility When sending files via FTP, the sender has no way to verify whether the recipient received or downloaded the file or not. Also, since FTP doesn’t maintain an audit trail of system actions such as who downloaded or transferred files, organizations don’t have detailed proof of user actions. Storage Overhead FTP doesn't allow sender to automatically expire or delete files. The file will be deleted until the IT administrator delete it, consuming significant storage space and incurring unnecessary costs. Cumbersome Workflow It is difficult and complexed to manage FTP, if you want to send the file to a new contact, you need to set a new FTP account. Because the users have no right to access the FTP server, thus they need to repy on the help of the IT administrator to create the new accounts, retrieve forgotten passwords and remove accounts for those who no longer require access. Alternative to FTP As the enterprise-level file transfer expert, Raysync replaces the FTP server via the secure file sharing platform, and builds the ultra-high-speed transfer engine to realize all internal and external file transfer management of the enterprise and fast and safe file distribution worldwide. Some of Raysync's differentiating features include: Easy to Management The deployment process will be troublesome and hard to manage if there are many files to be transferred. Raysync Transmission supports different types of protocol, based on the self-developed transfer engine, Raysync can transfer the large files and the vast amount of small files at maximum speed. It is convenience for organization to manage the whole transfer process from a central control board. Security and Permission Raysync helps organizations remain compliant with strict regulations by providing security features to monitor user actions, regulate access, and secure corporate data. All data in flight and at rest are protected with encryption and antivirus scanning. High-performance Transfer Whether it is the current TB-level big file transfer across borders or massive small file transfer, these are all routine for enterprises nowadays. FTP simply cannot meet the needs of the fast-growing big data era. Raysync Transmission is a high-speed transfer engine based on UDP research and development. Compared with FTP, the transfer speed is 100 times higher, and the bandwidth utilization rate reaches 96%. It can easily cope with the high-speed transfer demand of enterprise-level files.
