# Start logging
If ($Host.Name -ne "Windows PowerShell ISE Host") {
  $timestamp = Get-Date -Format yyyyMMddHHmmmss
  $filepath = "absolute_path_to_file\PowerShell_transcript."+$timestamp+".txt"
  Start-Transcript -Path $filepath -Verbose -NoClobber
}

# Store user credentials for resuse
$cred = Get-Credential -Credential domain\user_name

# Instnatiate session variables
$sess1 = New-PSSession -ComputerName computer_name -Credential $cred
$sess2 = New-PSSession -ComputerName computer_name -Credential $cred
$sess3 = New-PSSession -ComputerName computer_name -Credential $cred

# Connect to server1 and get backup status
Invoke-Command -Session $sess1 -ScriptBlock {Add-PSSnapin windows.serverbackup}
Invoke-Command -Session $sess1 -ScriptBlock {Get-WBSummary}

# Connect to server2 and get backup status
Invoke-Command -Session $sess2 -ScriptBlock {Add-PSSnapin windows.serverbackup}
Invoke-Command -Session $sess2 -ScriptBlock {Get-WBSummary}

# Remove sessions
Get-PSSession | Remove-PSSession

# End logging
If ($Host.Name -ne "Windows PowerShell ISE Host") {Stop-Transcript}
