PowerShell Script: Check Exchange Mailbox Database Last Backup Time

Post author:Written By 14 Comments

This script demonstrates a concept, but if you want a more complete working script use Get-DailyBackupAlerts.ps1 instead.

Here is a simple script you can use to check the last backup time for the mailbox databases on an Exchange Server. Run the script from the Exchange Management Shell on a Mailbox Server to check the local server’s databases.

[PS] C:Scripts>.check-dbbackups.ps1
Server: ESP-HO-EX2010B
Current time: 03/27/2011 22:21:39

Database                                Last Full (hrs ago)                     Last Inc (hrs ago)
--------                                -------------------                     ------------------
MB-HO-01                                1                                       n/a
MB-HO-02                                1                                       n/a
MB-HO-Archive-01                        n/a                                     n/a

Here is the script code.

$server = $env:computername

$now = [DateTime]::Now

"Server: " + $server
"Current time: " + $now

$db = get-MailboxDatabase -server $server -status
foreach ($objItem in $db)
{
$lastfull = $objItem.lastfullbackup
	if (!$lastfull)
	{
		$fullago = "n/a"
	}
	else
	{
		$fullago = $now - $lastfull
		$fullago = $fullago.TotalHours
		$fullago = "{0:N0}" -f $fullago
	}

	$lastinc = $objItem.lastincrementalbackup
	if (!$lastinc)
	{
		$incago = "n/a"
	}
	else
	{
		$incago = $now - $lastinc
		$incago = $incago.TotalHours
		$incago = "{0:N0}" -f $incago
	}


$returnedObj = new-object PSObject
$returnedObj | add-member NoteProperty -name "Database" -value $objItem.Name
$returnedObj | add-member NoteProperty -name "Last Full (hrs ago)" -value $fullago
$returnedObj | Add-Member NoteProperty -name "Last Inc (hrs ago)" -value $incago
$returnedObj
}

    This was helpful for me… I wanted the script to run, on a click, and wait for me to read the results before closing…

    Open notepad, paste the code below in…
    Save as something nifty like: “Check Exchange Last Backup.PS1”
    ——————————————————————————————-

    add-pssnapin Microsoft.Exchange.Management.PowerShell.SnapIn
    $server = $env:computername

    $now = [DateTime]::Now

    “Server: ” + $server
    “Current time: ” + $now

    $db = get-MailboxDatabase -server $server -status
    foreach ($objItem in $db)
    {
    $lastfull = $objItem.lastfullbackup
    if (!$lastfull)
    {
    $fullago = “n/a”
    }
    else
    {
    $fullago = $now – $lastfull
    $fullago = $fullago.TotalHours
    $fullago = “{0:N0}” -f $fullago
    }

    $lastinc = $objItem.lastincrementalbackup
    if (!$lastinc)
    {
    $incago = “n/a”
    }
    else
    {
    $incago = $now – $lastinc
    $incago = $incago.TotalHours
    $incago = “{0:N0}” -f $incago
    }

    $returnedObj = new-object PSObject
    $returnedObj | add-member NoteProperty -name “Database” -value $objItem.Name
    $returnedObj | add-member NoteProperty -name “Last Full (hrs ago)” -value $fullago
    $returnedObj | Add-Member NoteProperty -name “Last Inc (hrs ago)” -value $incago
    $returnedObj
    }

    Write-Host “Press any key to continue …”

    $x = $host.UI.RawUI.ReadKey(“NoEcho,IncludeKeyDown”)

      Robert, log on to http://www.microsoftvirtualacademy.com/ and enrol/watch the course ‘Getting Started with PowerShell 3.0 Jump Start’. In that you will learn why double-clicking on a .PS1 file won’t work (and why this is actually a GOOD thing!)

      You’ll probably have a bit of a laugh here and there too.

      PS – It’s free!

    Hi Paul

    Great script. As I am just learning PowerShell I only get about 70% of the script but it works fine on our Exchange 2007 box so thanks for that. One thing I have been trying is to output the results to a file so the Exchange Team can check the databases are being backed up. I have tried using a pipe to Out-file followed by the path to the text file but I end up with a text file with no data in it  if you could possibly advise how to output to a file it would be very much appreciated

    Thanks in advance

    Simon
