SyncFoldersUsingPowershell

In case of files uploaded through FTP Load Balancer, the uploaded files will be available only in 1 server whereas it should be available in all load balanced servers for reading it. This script helps to sync between 2 servers using RoboCopy windows command.

Why PowerShell instead of Batch Command

• Since the Copy operation can be failed due to various reasons, this should be monitored.
• Registering scripts as modules can be reused in case the same functionality is required for multiple operations
• Creating Task Schedulers and sending email about any failure in copy operation can be automated

What this scripts does

• By running setup.ps1, it registers 4 modules.

• UtilityModule - For registering other modules and has other utility functions -- Get-GSModulePath, Get-GSConfig, Get-GSConfigXml, Get-GSConfigPath, Set-GSConfig, Set-GSConfigXML, Copy-GSConfigFiles

• LogModule - Logging functions --Write-GSLog

• EmailModule - Email related functions --Send-GSEmail

• SyncFoldersModule - Task Scheduler and Copy operations -- Initialize-GSFoldersSync, Copy-GSFoldersAndFiles, Initialize-GSFoldersSyncScheduler, Confirm-GSFolderSync, Stop-GSFoldersSync, Confirm-GSFolderSyncConfig

• Registered modules can be found under the program files

  

• Creates new folder "[AppName]" in program files (x86)

• Copies all module's configuration files ".xml" to the new folder

• Creates 3 Task schedulers under "Microsoft -> Windows -> PowerShell -> ScheduledJobs"

• "[SchedulerNamePath1]" - For copying files from path1 to path2. Scheduler will start after 1 min on installation and restarts every day 12:00 AM

• "[SchedulerNamePath2]" - For copying files from path2 to path1. Scheduler will start after 1 min on installation and restarts every day 12:00 AM

• "[ValidateSchedulerName]" - For sending notifications about the copy operations. Scheduler will run for every 15mins

Configurations

GSSyncFoldersModule.xml

• AppName *^ – Schedulers and log uses this name
• Path1 * – From folder path to copy files
• Path2 * – To Folder path to save files (Path if not exists system will create)
• InstallationPath *^ – Path for storing the configurations and logs. New folder is created with the App name.
• ValidateSchedulerInterval * – Checks the status of the copy operation job on specified interval and triggers email
• RetryCount * – No of retries to perform when there is any error during copy operation
• WaitBtwnRetrySec * – Wait in seconds before next retry
• MonitorNoOfChanges * – Monitors no of new file or folder changes and if reaches the specified count, copy operation initiated
• MonitorWaitMin * – Wait for specified minutes before checking for any new files or folders and initiates copy operation
• SchedulerNamePath1 *^ – Task scheduler is created as “AppName. SchedulerNamePath1“ for copying files from Path1 to Path2
• SchedulerNamePath2 *^ – Task scheduler is created as “AppName. SchedulerNamePath2“ for copying files from Path2 to Path1
• ValidateSchedulerName *^ – Task Scheduler is created with this “AppName. ValidateSchedulerName“ to validate copy operation and sends status

GSEmailModule.xml – (Email triggered with the status of the copy operation)

• Mode * – SMTP / GMAIL
• Smtp -> Smtpserver (* in case of Mode is SMTP) – smtp Server name
• Smtp -> Port (* in case of Mode is SMTP)– smtp port number
• GMAIL -> Smtp (* in case of Mode is GMAIL) – smtp Server name
• GMAIL -> Port (* in case of Mode is GMAIL) – smtp port number
• GMAIL -> UserName (* in case of Mode is GMAIL) – Gmail email id
• GMAIL -> Password (* in case of Mode is GMAIL) – Gmail app specific password will be captured during installation step, should be blank
• FromEmailId * – From email id (When Mode is Gmail User Id will be always Gmail UserName)
• ToEmailId * - Multiple email address can separate by semicolon
• CCEmailId (Optional) – Multiple email address can separate by semicolon
• Subject * – Email subject for the status email. #STATUS# - Success / Fail, #EXECUTION_DATE# - Verified date time

GSLogModule.xml – (Logging the installation and job running status)

• LogMode * – FILE
• LogPath * – Log file path (Default: C:\Program Files (x86)\SynchronizeFolders)

Note:

• *- Mandatory configurations and cannot be blank
• ^- Modifications will not reflect immediately re-running setup.ps1 or specific module .ps1 is required
