SQL Server Database Backup using PowerShell

In this post we will see how we can take backup of databases from SQL Server using PowerShell and schedule it as a daily run Plan.

Step-1 : We will create Powershell Script to take backup of Databases in SQL Server.

Here is the full Script for your ready refrence.

param( $serverName, $backupDirectory )

[System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SqlServer.SMO”) | Out-Null

[System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SqlServer.SmoExtended”) | Out-Null

[System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SqlServer.ConnectionInfo”) | Out-Null

[System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SqlServer.SmoEnum”) | Out-Null

$server = New-Object (“Microsoft.SqlServer.Management.Smo.Server”) $serverName

$dbs = $server.Databases

foreach ($database in $dbs | where { $_.IsSystemObject -eq $False })

{

$dbName = $database.Name

$timestamp = Get-Date -format yyyy-MM-dd-HHmmss

$targetPath = $backupDirectory + “\” + $dbName + “_” + $timestamp + “.bak”

$smoBackup = New-Object (“Microsoft.SqlServer.Management.Smo.Backup”)

$smoBackup.Action = “Database”

$smoBackup.BackupSetDescription = “Full Backup of “ + $dbName

$smoBackup.BackupSetName = $dbName + ” Backup”

$smoBackup.Database = $dbName

$smoBackup.MediaDescription = “Disk”

$smoBackup.Devices.AddDevice($targetPath, “File”)

$smoBackup.SqlBackup($server)

“backed up $dbName ($serverName) to $targetPath

}

Save this Script file as ps1 extension.

You can create the script using even notepad.

 

Step 2: We will Create Batch file to call PowerShell scrip and to be used in Windows scheduler.

Save as .BAT file. Here is the batch script for ready refrence:

powershell -ExecutionPolicy RemoteSigned

-File “C:\User Data\SQL Backup\Tools\SQLServerBackupAllDatabase.ps1”

-serverName “INDEL-AXT5283NB”

-backupDirectory “C:\User Data\SQL Backup”

>> “C:\User Data\SQL Backup\LOG\\%date%.log”

Step 3 : Create a Windows Scheduler

Open Windows Task Scheduler.

Create New Task as shown below :

SCheduleJob-18

Enter Name & Description on General Tab as shown below:

SCheduleJob-18

On Trigger Tab create New Trigger and enter details as shown below :
SCheduleJob-18

On Action Tab Create Action and enter information as shown below : Here Select the batch file created in Step 2.

SCheduleJob-18

In Settings Tab do the setting as shown Below :

SCheduleJob-18

Click on OK to Save the Task and return to Task Scheduler Window.

Here you can see the newly created Task.

SCheduleJob-18

When Task is executed you will find the backup of databases at defined path in the script.

You can also find Log file at the path defined in batch.
