Simple file synchronization5/26/2023 ![]() ![]() instantiate the instance of the SyncId.įileStream fs = File. Create the file and store the guid which is used to Exists(syncFilePath)) //The ID file doesn't exist. ![]() Private static SyncId GetSyncID( string syncFilePath) The objective here is to have a unique SyncID. I have used the GUID for generating the SyncID, whereas you may also pre-defined file (File.ID) on the source and destination replicas. destination replicas or else retrieve the SyncID stored in a it is the first time a Sync is happening on the source and This is a private function I have created to generate the SyncID if make a call to the Synchronize method for starting the SyncDirection.UploadAndDownload for two way synchronization. treated as Destination and the Remote replica to be the source SyncDirection.Download if you want the Local replica to be Set the direction of synchronization from Source to destination knows which is the source and which one is the destination. destination replica as the Remote provider so that the agent assign the source replica as the Local Provider and the Initialize the agent which actually performs the create a FileSyncProvider object by passing the SyncID and theįileSyncProvider sourceReplica = new FileSyncProvider(sourceId, ) įileSyncProvider destReplica = new FileSyncProvider(destId, "C:\Sync\Destination\" ) Generate a unique Id for the destination and store it in a file Generate a unique Id for the source and store it in a file for Private void btnSynchronize_Click( object sender, EventArgs e) Write the following code in the Click handler of the button: Place a button named "btnSynchronize" on a form.Add reference to the assemblies "Microsoft.Synchronization" and ".Create a new windows application in Visual studio. ![]() ![]() Let's say I want to synchronize the contents of the folder C:\Sync\Destination with the contents of the folder C:\Sync\Source. The following program is just to give you a brief understanding of the technology. There are numerous ways of implementing this technology. Now I will write a simple application to demonstrate the File Sync Provider. For example if your application uses File Sync to synchronize data between folder C:\Sync\Folder1 and C:\Sync\Folder2, then these two folders can be termed as replicas. If you are wondering what is a Replica, it is the locations between which the synchronization would happen. The metadata is persisted in a file named "tadata" both in the source and destination replicas. The way the File Sync works is by comparing the metadata for the replica and detecting changes in files from the last time the replica was synchronized. Probably sometime soon I will write another article explaining how to utilize additional sync providers.Īs mentioned above, the File Sync provider is for synchronizing files and directories on the FAT or NTFS file systems. This article does not focus on writing a sync provider and just focuses on creating a small application to demonstrate the sync provider for File Systems. Provider for Feeds like RSS: For synchronizing data from Feeds. Provider for File Systems: For synchronizing Files and Folders on an NTFS or FAT file system. Provider for ADO.Net: For synchronizing data between ADO.Net supported data sources. The sync providers that are currently available from Microsoft are: Microsoft currently offers 3 types of providers that can be used by developers to write applications that can leverage the functionality in these providers. When we talk about synchronization, the things that come to our mind is efficiency, reliability, conflict resolution, etc and the Sync Framework handles all of these parameters gracefully with features like: updating incremental data changes instead of the entire dataset, defining conflict resolution policies, graceful cancellation of synchronizations when required without data inconsistencies, support for recycle bin, etc. In reality it is an extensible framework which can be used by developers to write sync providers that can sync data between devices/data sources or just use existing sync providers to create applications with data synchronization capabilities. This is the objective behind the framework. The Sync Framework is a Microsoft framework for developing systems that can synchronize any type of data between any type of device and across any type of network. In this process I came across the Microsoft Sync Framework which is still in the Community Preview phase but thought it would be a good idea to share my research with the community. Net environment, as the rest of the application(s) were to be written in C#. The problem was to search for a technology that would be effective and at the same time gel well with the. Currently I am working on a project that requires some files/folders to be synchronized at regular intervals across networks ranging in size from an inexpensive LAN to and expensive WAN. ![]()
