Check Backup files

The script below can be used to check multiple locations for SQL Server backups that have completed in the last 24 hours.

<# check.ps1 Script to check SQL Server backups on multiple servers
   This script must be run with sqlps.exe (not generic PowerShell)

   Limitations: SQL 2000 is not supported, use for SQL Server 2005 and above only.
   The account running this script must have access to all the databases.

# Read all the databases to be checked into a hash table

$t = Import-Csv -Path C:\batch\databases.txt -Header "database","server"
$Hash = @{}
foreach($r in $t)
{
	Write-Host $r.database $r.server
	$Hash[$r.database] = $r.server
}
# $Hash


# Query to retrieve backups

# n.b  compressed_backup_size is only available in 2008 and later
# so for now we just use the uncompressed backup_size.

$query = "SELECT  sdb.Name AS DatabaseName,
 COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_finish_date), 103), '') AS LastBackUpTime,
 COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_size), 103), '') AS size

   # Right-pad database name to 17 characters

   [string]$name =  $_ + "                 "
   $name = $name.substring(0, 17)

   # Get the backup size

   [int]$megabytes = $sqlcmd.size/1mb
   [int]$grandTotal = $grandTotal + $megabytes
   [string]$size = "       $megabytes"
   $size = $size.substring($size.length - 7, 7) + " MB  $server"

   # Store the backup date/time + Size in another hash table called $results
   $results.add($name,$sqlcmd.LastBackUpTime + $size  )

   # Count the number of backups (this will change if/when the list of databases to check is changed.)
   $countBackups = $countBackups + 1
}

# Display results for interactive use

Write-Host "-- Display results"
$results.GetEnumerator() | sort name | ft -HideTableHeaders -autosize

# Store all the results into some text files

$results.GetEnumerator() | sort name | ft -HideTableHeaders -autosize > c:\batch\backups.txt
$grandTotal > c:\batch\total.txt
$countBackups > c:\batch\count.txt

To have these results emailed to a person or group use a standard PowerShell email script to read and email the text files.
