Scripting DBs backup through Powershell - sql-server

Question

I have created a PowerShell script that takes the back up of entire structure of database. When it comes to jobs backup, I cannot find a possible solution to that.
$v = [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO')
if ((($v.FullName.Split(','))[1].Split('='))[1].Split('.')[0] -ne '9')
{
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMOExtended') | out-null
}
[System.Reflection.Assembly]:: LoadWithPartialName('Microsoft.SqlServer.SmoEnum') | out-null
set-psdebug -strict # catch a few extra bugs
$ErrorActionPreference = "stop"
$My = 'Microsoft.SqlServer.Management.Smo'
$srv = new-object ("$My.Server") $ServerName # attach to the server
foreach($sqlDatabase in $srv.databases)
{
$databaseName=$sqlDatabase.name
if ($databaseName.count)
{
$scripter = new-object ("$My.Scripter") $srv # create the scripter
$scripter.Options.ToFileOnly = $true
# we now get all the object types except extended stored procedures
# first we get the bitmap of all the object types we want
$all =[long]
[Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]:: all -bxor
[Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]:: ExtendedStoredProcedure
# and we store them in a datatable
$d = new-object System.Data.Datatable
# get everything except the servicebroker object, the information schema and system views
$d = $srv.databases[$databaseName].EnumObjects([long]0x1FFFFFFF -band $all) | Where-Object {$_.Schema -ne 'sys'-and $_.Schema "information_schema"
#Saving it in a directory
}
}
This scripts takes the back up of the db but take the structural back up of msdb. I studied Microsoft.SqlServer.SMO that says it has a job server agent and job collection function but it doesn't seem to work.

Answer 1

For jobs, use the JobServer.Jobs collection. You can similarly script other server-level objects.
Below is an example.
$jobsCollection = $srv.JobServer.Jobs
$scriptingOptions = New-Object Microsoft.SqlServer.Management.Smo.ScriptingOptions
$scriptingOptions.IncludeIfNotExists = $true
$scriptingOptions.AppendToFile = $false
$scriptingOptions.ToFileOnly = $true
foreach ($job in $jobsCollection) {
Write-Host "Scripting $($job.Name)"
$scriptingOptions.FileName = "C:\ScriptFolder\Jobs.sql"
$job.Script($scriptingOptions)
$scriptingOptions.AppendToFile = $true
}

Answer 2

Although the answer given by Dan helped me but it wasn't creating a script in the folders. It was just creating folders with the jobs names. So, I did something like this :
foreach($sqlDatabase in $srv.JobServer.Jobs)
{ $databaseName=$sqlDatabase.name
write-host("I am her '$databaseName' ");
$scripter = new-object ("$My.Scripter") $srv # create the scripter
$scripter.Options.ToFileOnly = $true
$d = new-object System.Data.Datatable
$d=$srv.JobServer.Jobs[$databaseName]
$d| FOREACH-OBJECT {
trap [System.Management.Automation.MethodInvocationException]{
write-host ("ERROR: " + $_) -Foregroundcolor Red; Continue
}
# for every object we have in the datatable.
$SavePath="$($DirectoryToSaveTo)\$($ServerName)\$($databaseName)\$($_.DatabaseObjectTypes)"
# create the directory if necessary (SMO doesn't).
if (!( Test-Path -path $SavePath )) # create it if not existing
{Try { New-Item $SavePath -type directory | out-null }
Catch [system.exception]{
Write-Error "error while creating '$SavePath' $_"
return
}
}
# tell the scripter object where to write it
$scripter.Options.Filename = "$SavePath\$($_.name -replace '[\\\/\:\.]','-').sql";
# Create a single element URN array
$UrnCollection = new-object ('Microsoft.SqlServer.Management.Smo.urnCollection')
$URNCollection.add($_.urn)
# and write out the object to the specified file
$scripter.script($URNCollection)
}
}
