Load Balancer Syncronizer

What is it?

It's simply a file synchronizing program where you have couple of servers/files to sync. These files can be in different machines but they should be linked in one server as a shared folder.

Provides a background override operation with check to a database table consists of a path, sync status and publish time.

Dependencies

7-Zip.exe LICENCE

Prerequisites

• 7zip: Needs to be downloaded and placed in bin\Debug or bin\Release folder with 7-Zip filename. The path to 7-Zip should look like ...\bin\Release\7-Zip or ...\bin\Debug\7-Zip

If you want to use background synchronization;

• A database connection(can be SQLServer or MySql) and a table: The table that is used for file checks is named ApplicationSyncPath and its columns are as follows:

  Field Name	Type
  isSynced	tinyint
  path	varchar
  CreatedAt	datetime
  UpdatedAt	datetime
  ErrorMessage	varchar
  Id	int
  PublishTime	datetime

How To Install

1. Download 7-zip either from FileHippo or from 7-Zip.org and install 7-Zip.
2. Place your installed 7-Zip folder either in bin/Debug directory or in bin/Release directory of the project. Depending on which mode you are running your application in Visual Studio.
3. Open the solution in Visual Studio, then from the menu Build > Rebuild Solution
4. Open the bin/Debug or bin/Release directory of the project, and run LoadBalancerSyncronizer.exe

How To Use

• When application is launched, click on the buttons to setup paths of each directory.

  Right click any button for overriding contents from main folder to target folder.

• Override does not empty the target folder only overrides the files with the same name.

  

How Does It Work

• Main Dir button denotes, path to copy from.
• Override Dir buttons are for overriding to those directories: First files are zipped into tar format, then copied in big chunks(4MB), then extracted at the target folder.

If you want to use background syncronization;

• DB Settings button is for those who want to sync server files from database.

  • Background operation is checking ApplicationSyncPath table every 10 seconds.
  • It syncs paths of which isSycned property is set to false/0 and PublishDate property is over due.

• Sync via Server Root Paths button works as follows:

  TextBoxes are for server roots ie. C:\wamp\www.

  • First textbox is your main server.
  • It's relative paths ie /images/logo.png in ApplicationSyncPath table will be to copied to other textboxes' directories.
  • Other TextBoxes are for your other servers root paths, to override to.
