PowerShell script to take Backup

SharePoint administrators need to run regular backups using PowerShell, the STSADM tool or in Central Administration.

Script :

Add-PsSnapin Microsoft.SharePoint.Powershell –ErrorAction SilentlyContinue

try

 {

    $today = (Get-Date -Format dd-MM-yyyy)

    $backupDirectory = "C:\Backup\DailyBackUp\$today"

  # Backup file Location

    $backupFile = "C:\Backup\DailyBackUp\$today\Backup.dat"

  # Log file location

    $logFile = "$backupDirectory\BackupLog.log"   

  # Address of the Site Collection to backup

    $Site = "http://Spserver1:2000"

   

 # Location of the Backup Folder

    if (-not (Test-Path $backupDirectory))

    {

      [IO.Directory]::CreateDirectory($backupDirectory)

      #New-Item $logPath -type $backupDirectory

    }

  

 # Get backup start date and time

    $backupStart = Get-Date -format "MM-dd-yyyy HH.mm.ss"

   

  # creates a log file  Start-Transcript -Path

    Start-Transcript -Path $logFile

     

 # This will actually initiate the backup process.

      Write-Host   

      Write-Host   

      Write-Host "Backup starting at $backupStart for $Site "   

      Write-Host "******************************************"

     Backup-SPSite -Identity $Site -Path $backupFile -Force

     $backupComplete = Get-Date -format "MM-dd-yyyy HH.mm.ss"

      Write-Host   

      Write-Host   

      Write-Host "Backup Completed at $backupComplete for $Site "   

      Write-Host "******************************************"
