teamcity Backup TeamCity Backuping using TeamCity API

Example

First of all, Ensure that the user which will be running this call has the Change backup settings and control backup process privilege.

# 
# TC Backup Launcher
# Script to launch a backup on the TeamCity Server
#
Param(
    [Parameter(Mandatory=$true)][string]$username,
    [Parameter(Mandatory=$true)][string]$password
)
Begin
{
    $url = "http://teamcity:8111/httpAuth/app/rest/server/backup?includeConfigs=true&includeDatabase=true&includeBuildLogs=false&fileName=TeamCity_Backup"
    $username = <username>
    $password = <password>
    
    # Function to realize a POST Operation
    function Execute-HTTPPostCommand() {
        param(
            [string] $target = $null
        )
        $request = [System.Net.WebRequest]::Create($target)
        Write-Host "POST: " $request.RequestUri
        
        $request.PreAuthenticate = $true
        $request.Method = "POST"
        $request.ContentType = "application/xml"
        $request.Headers.Add("AUTHORIZATION", "Basic");
        $request.Accept = "*"
        $request.Credentials = New-Object System.Net.NetworkCredential($username, $password)
         
        $response = $request.GetResponse()
        $xmlout = ""
        
          if($response)
          {
              $sr = [Io.StreamReader]($response.GetResponseStream())
              $xmlout = $sr.ReadToEnd()
          }
        return $xmlout;
    }
    
    Write-Host "Creating a new Backup:"
    
    Execute-HTTPPostCommand $url
}

The important part is the URL to call with method POST :

http://teamcity:8111/httpAuth/app/rest/server/backup?includeConfigs=true&includeDatabase=true&includeBuildLogs=false&fileName=TeamCity_Backup

You can specify the settings you want to backup as in the web interface.
