Find the amount of time it takes to complete a script

Lately I've been running nightly backups against my main computer at midnight every night which got me wondering . . . how long does it take to complete the backup?

Below are a few lines of code that can be added to any script to find out how long it takes your script to complete.

## Begin the timer.
$StartTime = (Get-Date)

## Begining of code.
hostname ; Get-Counter -Counter "\Memory\Available MBytes" -SampleInterval 1 -MaxSamples 3
## End of code

## Stop timer.
$EndTime = (Get-Date)

## Calculate amount of seconds your code takes to complete.
"Elapsed Time: $(($EndTime - $StartTime).totalseconds) seconds"

Make PowerShell startup blazing fast!!

If you use PowerShell...You HAVE to run this script! This will cut the time it takes PowerShell to start in half!

Function Improve-GAC { Set-Alias ngen (Join-Path ([System.Runtime.InteropServices.RuntimeEnvironment]::GetRuntimeDirectory()) ngen.exe)
 [AppDomain]::CurrentDomain.GetAssemblies() |
    sort {Split-path $_.location -leaf} |
    %{
        $Name = (Split-Path $_.location -leaf)
        if ([System.Runtime.InteropServices.RuntimeEnvironment]::FromGlobalAccessCache($_))
        {
            Write-Host "Already GACed: $Name"
        }else
        {
            Write-Host -ForegroundColor Yellow "NGENing      : $Name"
            ngen $_.location | %{"`t$_"}
         }
      }
}Improve-GAC

Backup Windows 8.1

Here is a short little PowerShell Function that I use to create a scheduled job that runs every night at midnight that backups my C:\ drive to my E:\ drive.

The code used to backup Windows 8.1:

wbAdmin start backup -backupTarget:E: -include:C: -quiet

Function Create-ScheduledJob {
<#
.Synopsis
   schedules nightly backups.
.FUNCTIONALITY
   PowerShell v3.0+
#>
[CmdletBinding()]
    Param( [Parameter( Mandatory = $True )]
           $JobName,
           [Parameter( Mandatory = $True )]
           $ScriptToRun,
           $VerbosePreference = "Continue" )

Begin{ $Trigger = (New-JobTrigger -Daily -At 12:01AM) }

Process{ Register-ScheduledJob -Name $JobName -Trigger $Trigger -ScriptBlock { "& wbAdmin start backup -backupTarget:E: -include:C: -quiet" } }

End { Write-Verbose "Your new ScheduledJob has been created successfully!" }

}Create-ScheduledJob
