For example, it can move files from one folder to another without the need to delete and recopy the file again to the new location. The Intelligent Synchronization in SyncBackPro and SyncBackSE uses an internal database to track the state of files and has several powerful options that can be configured. Using file sync software is useful in situations where you want files in both locations synchronized, such as document files between a home PC and an office laptop. This allows for much finer control over what actions to take based on what has changed and allows for change detection such as the file only being modified in the source or destination. Intelligent Synchronization is a bidirectional sync method that also tracks a history of files location during the last synchronization. SyncBackFree comes with Basic Synchronization only. SyncBackPro and SyncBackSE support Intelligent Synchronization. In a two-way file synchronization, updated files are copied in both directions - from the source to the destination, and from the destination to the source, usually with the purpose of keeping both locations identical to each other. What is file synchronization and file sync software?įile synchronization is a file copying method between two locations so that the contents between them are up to date. At the end of the process, the same latest file will be on both PCs and USB drives, which is useful for data backup.File Synchronization with SyncBack Author: Conrad Chung, 2BrightSparks Pte. The drive works normally and performs the same synchronization between the PC-2 and the portable USB drive. If the files on the home computer (PC-1) must be synchronized with the files on the computer (PC-2) 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. Synchronization between unconnected computersįor computers that are not connected to the network, you can use a portable USB drive to synchronize. The ultimate goal is to ensure that the selected folder on the computer and/or drive has the same latest files. Synchronization between computer and NAS. Synchronization between computer and external drives (USB). The computer can be a laptop, desktop, workstation, server. Synchronization between computers connected to the Internet (WAN). For cross-computer sharing of selected folders, use Windows file sharing and sync use and vice versa. Synchronization between computers connected to a local network (LAN). Auto-Syncįile synchronization can be run automatically at irregular intervals, ie every 10 minutes, every 2 hours, etc., at scheduled times (ie 7:00 on Monday and Friday), in real-time (ie after file changes are completed). Similarly, if a file is deleted from location A, it will be deleted from location B. However, if the file in location B is newer, it will not be copied to location A. Since only new files are changed, this is very useful and effective for backup.Įxample: If the file is newer in location A (source), it will be copied to location B (destination). This will create an exact 1:1 copy of all files in the "source to target". It is said that Source has been mirrored to Target. The file is pushed away from the source to target (or the file is pulled from source to target, but always in only one direction). Ø NE location is considered the source and the other is considered the target. These two positions are not considered equivalent. To coordinate changes, the synchronization process copies files in only one direction. The file can only be changed in one location. Also deleted from position B, and vice versa. Similarly, if a file is deleted from location A, the file will be copied. However, if the file is newer in location B, it will be copied to location A. These two positions are considered equivalent.Įxample: If the file is newer in location A, it will be copied to location B. It is expected that the file will change in both locations. This synchronization process copies files in both directions to coordinate changes as needed. What is One-Way Synchronization and Two-Way Synchronization? Two-Way Synchronization Synchronization can be "two-way" or "one-way". If you add, change, or delete files from one location, the synchronization process will add, change, or delete the corresponding files in another location. File synchronization is the process of ensuring that two or more locations contain the same latest files.
