Raysync Tutorial - Three File Sync Modes You Should Know
In order to solve the problem of fast synchronous backup of large files, based on the high-speed transfer protocol, Raysync developed the synchronous backup function of GB/TB large files, which can increase the speed by more than 30 times. There are three modes of the file sync function of Raysync, as follow: 1. Select file sync in every second/minute/hour. Enter the interval time in the input box, and select the time unit in the drop-down box. For example, if 60 seconds is set, the synchronization task will implement every 60 seconds. 2. Select to run the sync task in XX hours XX minutes every day. Time can be customized in the input box, for example, 16:10 every day, it will automatically start to sync at 16:10 every day. 3. Synchronize once at a specific time. Raysync supports file sync only once at a specific time. For example, if you set the sync time at 2021-12-13 11:00, the sync task will execute at this time only once.
What is One-Way Synchronization and Two-Way Synchronization?
File synchronization is the process of ensuring that two or more locations contain the same latest files. If you add, change, or delete files from one location, the synchronization process will add, change, or delete the corresponding files in another location. Synchronization can be "two-way" or "one-way". Two-Way Synchronization This synchronization process copies files in both directions to coordinate changes as needed. It is expected that the file will change in both locations. These two positions are considered equivalent. Example: If the file is newer in location A, it will be copied to location B. However, if the file is newer in location B, it will be copied to location A. Similarly, if a file is deleted from location A, the file will be copied. Also deleted from position B, and vice versa. One-Way Synchronization The file can only be changed in one location. To coordinate changes, the synchronization process copies files in only one direction. These two positions are not considered equivalent. Ø NE location is considered the source and the other is considered the target. The file is pushed away from the source to target . It is said that Source has been mirrored to Target. This will create an exact 1:1 copy of all files in the "source to target". Since only new files are changed, this is very useful and effective for backup. Example: If the file is newer in location A , it will be copied to location B . However, if the file in location B is newer, it will not be copied to location A. Similarly, if a file is deleted from location A, it will be deleted from location B. However, the file is deleted in location B was recovered using this file. In position A. Auto-Sync File synchronization can be run automatically at irregular intervals, ie every 10 minutes, every 2 hours, etc., at scheduled times , in real-time . Detected at startup or shutdown. Common File Synchronization Solutions Synchronization between computers connected to a local network .The computer can be a laptop, desktop, workstation, server. For cross-computer sharing of selected folders, use Windows file sharing and sync use and vice versa. Synchronization between computers connected to the Internet .This requires a VPN tunnel. The computer can be a laptop, desktop, workstation, server. Synchronization between computer and external drives.Synchronization between computer and NAS. The ultimate goal is to ensure that the selected folder on the computer and/or drive has the same latest files. Synchronization between unconnected computers For computers that are not connected to the network, you can use a portable USB drive to synchronize. If the files on the home computer must be synchronized with the files on the computer at work, you can synchronize the PC-1 with a portable USB drive, and then connect the PC-1 with the portable The USB drive is synchronized to achieve synchronization. The drive works normally and performs the same synchronization between the PC-2 and the portable USB drive. At the end of the process, the same latest file will be on both PCs and USB drives, which is useful for data backup.

How to achieve file synchronization between corporate headquarters and branches?
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.

Advantages and Disadvantages of Synchronous and Asynchronous Transmission
Synchronous Transmission Synchronous transmission is the transmission of data in units of data frames. Frame synchronization signals in the form of characters or bit combinations can be used. The transmitter or receiver provides a clock signal dedicated to synchronization. In short-distance high-speed transmission, the clock signal can be transmitted by a dedicated clock line; when the computer network adopts the synchronous transmission method, the clock synchronization signal is often embedded in the data signal frame to achieve clock synchronization between the receiver and the transmitter. In digital communication, synchronization is very important. When the transmitter transmits data information to the receiver through the transmission medium, for example, each time a character data signal is sent, the receiver must recognize the start bit and end bit of the character data signal To correctly read each bit of the data signal of the character at the appropriate time, this is the basic synchronization problem between the receiver and the transmitter. When transmitting data signals in data frames, to ensure the integrity and accuracy of the transmitted signal, in addition to requiring the receiver to be able to recognize the start and end of the signal corresponding to each character , to ensure that the reading starts and ends at the correct time Retrieving the signal means maintaining the integrity of the transmitted signal; it is also required to keep the clock and the transmitter at the same frequency to ensure that the number of signal units reads per unit time is the same, that is, to ensure the accuracy of the transmitted signal. Therefore, when transmitting data signals in data frames, the transmitter is required to take the following two measures for the transmitted signals: ①Add a start signal and a stop signal different from the data signal before and after the corresponding signal of each frame of data; ② Add a clock synchronization signal before the data signal of each frame to control the clock synchronization of the receiver. Asynchronous Transmission Asynchronous transmission is the transmission of data in units of characters, using character synchronization signals in the form of bits. The transmitter and receiver have independent clocks , and neither side provides clock synchronization signals to the other side. . The sender and receiver of the asynchronous transmission do not need to coordinate before the data can be transmitted: the sender can send data at any time, and the receiver must be ready to receive data at any time. The asynchronous transmission mode is generally adopted between the computer host and the input and output devices. Such as a keyboard, a typical RS-232 serial port : the sender can send a character at any time . The Advantages and Disadvantages of Asynchronous and Synchronous Data Transmission 1. Asynchronous transmission is the character-oriented transmission, while the synchronous transmission is bit-oriented. 2. The unit of asynchronous transmission is character and the unit of synchronous transmission is a frame. 3. Asynchronous transmission seizes the opportunity of re-synchronization through the start and stops codes of character start and end, while synchronous transmission extracts synchronization information from the data. 4. The asynchronous transmission has lower requirements on timing, and synchronous transmission often coordinates timing through a specific clock line. 5. Asynchronous transmission is less efficient than synchronous transmission. To Sum Up Both asynchronous transmission and synchronous transmission have the above basic synchronization problem: character synchronization or frame synchronization signals are generally used to identify the start and end of transmitting character signals or data frame signals. The main difference between the two is whether one of the transmitter or receiver sends a clock synchronization signal to the other party.
How to Securely Realize File Synchronization?
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.
Raysync Transmission: Problems and Solutions to File Sharing
In July 2018, the popular file-sharing service DropBox gave Northwestern University ‘access to project-folder-related data’ over a two-year period from about 400,000 users across 1,000 universities. Technical security of such electronic file-sharing systems has been breached and management failures have occurred from time to time. Whether it is for commercial purposes or other reasons, when it comes to file sharing services, we need to think about more than security. There are other aspects to file-sharing that should be considered, namely: 1. privacy of the sharing mode 2. the geo-location of your data 3. the file sharing restriction The file-sharing mode can be divided into two types, one is classical mode, the other is the guest mode. In the classical mode, the users has the right to manage the folders and files as the administrator. Open the guest account and set the sharing mode to guest only. In guest-only mode, the user's user name and password are only used to verify whether the user has permission to access the computer, and the operations on files and folders are performed as guest accounts. Although only relative aspects of guest mode are accessed, this mode is not convenient for fine control of permissions. One of the important aspects to choose a file-sharing provider that should be considered is the geo-location of your data. The reliability and cost of the file transfer over long distances should also be considered. For many enterprises, it doesn't matter on which disk the business data is stored in the world, but unified management and comprehensive analysis need to take into account the importance of ensuring the integrity and security of shared files when exchanging personal or confidential data between continents and countries. The security restriction reveals in two places of file-sharing. The first place is that when sharing is enabled, the corresponding account needs to be assigned the right to access this computer from the network. Account A has added the right here, so when sharing is enabled, the user name A can be entered to open sharing, otherwise, it will be prompted that there is no right to access network resources. Therefore, any problem that involves not being able to access the host because of permissions is a problem of sharing permissions. The second place is NTFS permissions for shared folders and their subfolders, which are set in the security tab of the folder's properties. The permissions control a user's operating permissions on folders and files. Therefore, any problem that files cannot be added, deleted, or modified is set here. As a professinal enterprise-level solutions provider in file sharing, Raysync Transmission has a different working model. Our view on such issues is that not only should your files be kept safe, but also your usage patterns and sharing permissions should be controlled by yourself. As an expert providing the one-stop enterprise-level large file transmission solution, banking-standard security encryption, intelligent synchronization, flexible authorization, high-speed and stable cross-border and cross-regional transmission are the foundation of Raatsync Transmission.
