Synchronization is a fairly capacious concept and is used in a variety of fields, from computer science to physics. This phenomenon can occur to users of smartphones and computers; game lovers also encounter this concept.
In the age of universal informatization and computerization, it is impossible to do without special methods that make it possible to organize the endless flow of information. In addition, all modern electronic devices and programs for them are closely connected via the Internet, and therefore it is necessary to ensure their joint functionality. Moreover, synchronization as an informational phenomenon is of fundamental importance for manufacturers of applications and technical devices, on the one hand, and on the other hand, it greatly facilitates the work with user target information.
What is synchronization
Synchronization is a system of algorithms that ensure the parametric unity of different objects in time and space. Depending on the nature of the process, synchronization of data and processes is distinguished.
Each device provides for the presence of certain synchronization algorithms in relation to other devices. When contact occurs between the computer and smartphone, synchronization is established. This allows you to make changes on your computer that will also be reflected on your phone, and vice versa.
When using huge amounts of data every day, synchronization is used to avoid their deformation and protection from interference, which can be reflected in the form of incorrect parameters that impede the operation of the recipient device.
Backup
Now another look at the term “synchronization”. What is this in terms of backup? In fact, this also implies the process of simultaneously changing data and then saving it. But there can be two options. For example, on a computer, a copy can be stored in a specially allocated disk partition, or it can use cloud storage.
In both the first and second cases, synchronization occurs simultaneously, but to use the “cloud” the main condition is the presence of an uninterrupted Internet connection, and when saving a backup copy on the hard drive, additional disk space is used. However, what exactly to prefer, everyone decides for himself.
In any case, you can make backups both using the system and using special programs. However, to obtain simultaneous data changes, you will need to select appropriate criteria (for example, creating dynamic partitions to increase the volume when there is a lack of space). In this regard, “cloud” technologies look more attractive, however, even for such storages, limits on the use of free disk space without payment are often set.
Why is it needed?
This system has many purposes, some of them are formed for security reasons, others serve to optimize the connection of servers, the rest are necessary to ensure the functionality of programs and applications, including many computer games. Data synchronization is a multifunctional process, however, from the point of view of the interaction of a computer, smartphone, servers and other identical devices via the Internet, this process arises from the following problems:
- Protecting source data from interference.
- Copying data.
- Identification of users on the network.
- Storing the results of ongoing processes.
- Ensuring the compatibility of the software of one device in relation to another.
- Routing (direction) of information arrays.
Security risks of remote work
While some employers fear that remote work will lead to lost productivity, the real concern is the security of the proprietary and mission-critical data that modern companies rely on.
On a corporate network, IT teams can easily ensure device security, but with remote access, this is more difficult. Outside the corporate network, devices become targets for cybercriminals. An attack on unprotected endpoints could expose an employee's credentials and allow the attacker to gain access to the company's system. But this is not a reason to refuse to implement the technology, but to consider all the nuances before choosing a supplier.
Phone synchronization
Many cellular users are smartphone owners. Typically, these types of phones contain many important components: application data, system data, and user information. To ensure full functionality, synchronization in the phone is required. The following example will help explain what this is.
A notes application was installed on phone “A” from account “X”. During the operation of the phone, data was entered there, but one day the phone crashed, and the information storage device was irretrievably destroyed. The owner purchased a new phone “B”, on which he installed the same application using the same account “X”. All past notes remain in the application and can be used.
The basis of this good news for the user is synchronization - this manifested itself in the saving and copying of user data in the application, which was always synchronized with the cloud and securely stored. The same principle of operation applies to other devices - they all store the latest version of the file.
⇡#GoodSync
- Developer: Siber Systems
- Distribution: shareware
- Russian interface: yes
This utility is notable for the fact that it was created by the developers of the popular RoboForm password saving program. The application is well translated into Russian (amateur translations into other CIS languages are available), has a version for Windows and Mac, as well as a separate portable version for running from a flash drive. GoodSync is a shareware program and after thirty days of use it imposes restrictions on the number of files in a task (no more than one hundred) and the number of tasks itself (no more than three). However, the price is quite affordable: 595 rubles for the version for Windows and 795 rubles for the version for Mac.
GoodSync main window
Work in the program begins with adding tasks. They come in two types: synchronization and backup. Each task is displayed on a separate tab with its own settings. Regardless of what type of task you choose, you need to specify the left and right data folder. For both the source and destination paths, there are a large number of places available where files can be stored: your computer, other computers on the local network, FTP protocols, WebDAV, Amazon S3 cloud storage, Google Drive, Windows Azure, SkyDrive, connected devices on Windows Mobile, as well as its own GoodSync Connect service. The program has no restrictions on data exchange and allows you to compare all supported sources with each other. We should also talk about GoodSync Connect: it is a P2P network that allows you to synchronize data on several computers via the Internet. Thus, you do not need to connect computers to a local network or use a USB device for transfer, and the files will not be stored in the cloud. To use GoodSync Connect, you need to configure your computers by creating an account on the system.
Selecting a folder in GoodSync
By selecting the left and right folders, you can run a preliminary analysis or immediately begin synchronization. The main window will display a list of synchronized files in the form of a tree, indicating the size, date and copying direction (from left to right, from right to left). You can view individual categories of files (changed, new and others) and exclude or, conversely, enable their copying, as well as change the direction. In the task settings, you can specify parameters for its automatic execution: when a file is changed, when the program starts, periodically, when connecting folders, before logging out. It is possible to schedule a task using the standard Windows scheduler in login mode or without it. An interesting option is that you can specify the percentage of changes above which synchronization will not occur. Another feature that can be configured is the way conflicts are resolved automatically: skip, replace with later files, and so on. In addition to the parameters for automatically completing a task, the settings include other options where you can place many checkboxes next to items such as “Keep backup copies of deleted files” or “Copy file creation time,” apply a filter to certain files and folders, etc.
Job Options in GoodSync
The program can work in mini mode - it will be displayed as a small panel with a list of active tasks, which allows you to do other things and at the same time control the progress of synchronization. Finally, it is worth mentioning the GoodSync Explorer application, which is additionally installed on your computer - with its help you can view the directories in which your data is stored and add bookmarks to the desired places. These bookmarks can then be used when selecting a source for folders when setting up a job in GoodSync.
Computer synchronization
Despite the differences between a computer and a phone, the principles and purpose of synchronization are similar. The only differences lie in the volume of synchronized information and its quantity.
Timely updating, as well as data protection of files and applications, which is achieved by saving the latest versions of files on other devices connected to it, and synchronization with the computer. It goes without saying that this is very important: the user’s entire workspace is reliably protected from outside interference and loss of important information.
⇡#Allway Sync
- Developer: Usov Lab
- Distribution: shareware
- Russian interface: yes
The Allway Sync program is provided by the developers free of charge for personal use; the commercial version of the application costs $19.95. The utility is quite simple and easy to use, although it has a somewhat unsightly interface (Russian language support is present). There is no list of profiles, but rather tasks, each of which is displayed on a separate tab: you can add, delete, clone and rename them. To set up a task, you need to specify two folders for synchronization and mark its direction. The program allows you to select folders not only on a local drive, but also on the Internet - it supports FTP, SFTP, WebDAV protocols, online services Dropbox, SkyDrive, Google Docs, OffsiteBox and others, detects mobile devices connected via Microsoft ActiveSync, and can also read ZIP archives. Moreover, unlike the SyncBack Pro program, which has similar functionality, in Allway Sync you can add a connection between online folders - for example, synchronize your Dropbox account with an FTP service.
Selecting the synchronization direction in Allway Sync
The selected folders need to be configured (the type of setting will depend on which folder you specified: if on a local drive, you need to specify the directory, if FTP, enter the server parameters, if Google Docs, specify the e-mail and password for your account, and so on) . The direction of synchronization is indicated between the folders: initially it is two-way, that is, the files will be identical in both places, but it can be changed to one-way by selecting the side that will become the data source. By the way, during general synchronization of folders there can be more than two - you have the opportunity to configure mirroring of an unlimited number of data sources.
After setting up the task, you can click the “Analyze” and “Synchronize” buttons. The program recommends performing a preliminary analysis so that you can make sure that everything will happen as expected. It will build a detailed report in which new/unchanged/all/excluded files will be grouped into tables, indicating the name, size, time and direction of synchronization. Important messages related to file changes can be displayed separately.
Report on analyzed files in Allway Sync
In the Allway Sync options there is a section “Profile Settings”, where for each task a set of additional properties is displayed: “Synchronization Rules”, “Automatic Synchronization”, “Inclusive and Exclusive Filters”, “Version Control Policy”, “Error Handling”. Let's take a closer look at them. In synchronization rules, you can activate several important options - ignore the hourly difference in modification time, copy security attributes, etc. Automatic synchronization settings allow you to select a start condition: when a removable drive is connected, when file changes are detected, or the computer is idle, etc. Inclusion and exclusion filters are highly customizable: you can apply them to file names or extensions, status (new, modified, deleted), attributes (system, compressed, etc.), modification time, and size. A versioning policy allows you to choose what to do with old versions of changed files: delete them or move them to a specific folder, and also specify how long these old versions should be kept. In the settings related to error handling, you can specify what the program should do in the event of these errors and determine its behavior when a warning appears.
Allway Sync Options
Finally, it’s worth adding that, like the previously discussed utilities, Allway Sync keeps a log of actions in a log and allows you to import and export application settings.
Synchronization in games
Computer games can be single-player or multi-player. Players in multiplayer games often ask questions about why synchronization is needed in the game, what it means and why it is necessary.
The first encounter with synchronization occurs because game developers are trying to protect their product from theft. This endeavor is based on synchronizing a licensed product via the Internet; it is essentially similar to entering a registration key, also included with the game. This way, the user verifies the authenticity of the product and guarantees its functionality, and the developer verifies that a licensed version of the game is being used.
The second and permanent contact occurs with the start of the game. All data about accumulated game values, mission progress, etc. are stored on the developer’s servers, so users can leave the game at any time, saving accumulated achievements. Also, to ensure the simultaneous presence of a large number of people on game servers, the data of each player is synchronized and compiled through the game engine on a remote server.

Sync folders
In fact, this process is little different from the synchronization of applications and programs and is designed by its specifics for use in closed systems that involve the exchange of information.
Folder synchronization is the process of continuously or scheduledly saving copies of folders to a different location on a different storage device, such as from one hard drive to another.
The purpose of executing these algorithms is to protect them from loss and distortion of the primary version during the transfer of this folder to another device storing information.
Using Enterprise file synchronization and sharing tools
Enterprises use EFSS for content management, collaboration, and secure file sharing among employees.
EFSS services include features such as online comments, document version tracking and workflow tracking. Organizations often use this technology as a means of preventing unwanted exchange of corporate data between employees - for this purpose, the progressive products of the line include security features: authentication, data encryption, containerization. Some EFSS services allow IT administrators to set access policies that control who in the organization has access to content.
Methods
Synchronization is a significant condition for the normal functioning of information systems. To ensure the functioning of large systems containing some information, regardless of the device type and nature, 2 synchronization methods are used:
- Unilateral. Consists of checking matches between two devices or servers and replacing the parameters of the synchronization object on the slave device. This is reflected in the phone and app example above: the server containing the app's information is a priority member of the network, so all updates will be recorded and saved to all devices running the same app.
- Bilateral. The essence of this approach to synchronization is to access a base of criteria by which a priority device is allocated and the amount of information that must be updated on a slave device is determined. Sometimes the user is asked to choose which storage location to update the information from.

What are the consequences of lack of synchronization?
In many cases, the user is trusted to independently determine the synchronization parameters, including disabling it or limiting it. But what could be the consequences of such a decision?
For those who use smartphones, it is common to accumulate a large amount of contact data and personal information; the loss or damage of the device will greatly upset the owner, and in addition, all collected information will be lost if synchronization is disabled on the phone. What does this mean? The need to restore all data manually, which is extremely inconvenient and not always possible.
Computer storage stores accumulate even more information, but synchronization can be disabled. Is it worth doing? Probably not: if the equipment fails, the results of the work will be lost forever.
Information technology manufacturers know that synchronization is a primary condition for the security of user data, so they are improving it every year.
