Function Remove-SqlDatabaseSafely
{
<#
.SYNOPSIS
Safely removes a SQL Database and creates an Agent Job to restore it
 
.DESCRIPTION
Performs a DBCC CHECKDB on the database, backs up the database with Checksum and verify only to a Final Backup location, creates an Agent Job to restore from that backup, Drops the database, runs the agent job to restore the database,
performs a DBCC CHECKDB and drops the database
 
By default the initial DBCC CHECKDB is performed
By default the jobs and databases are created on the same server. Use -Destination to use a seperate server
 
It will start the SQL Agent Service on the Destination Server if it is not running
 
.PARAMETER SqlServer
The SQL Server instance holding the databases to be removed.You must have sysadmin access and server version must be SQL Server version 2000 or higher.
 
.PARAMETER SqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted.
 
$scred = Get-Credential, then pass $scred object to the -SqlCredential parameter.
 
Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user.
 
.PARAMETER Destination
If specified this is the server that the Agent Jobs will be created on. By default this is the same server as the SQLServer.You must have sysadmin access and server version must be SQL Server version 2000 or higher.
 
.PARAMETER Databases
The database name to remove or an array of database names eg $Databases = 'DB1','DB2','DB3'
 
.PARAMETER NoCheck
If this switch is used the initial DBCC CHECK DB will be skipped. This will make the process quicker but will also create an agent job to restore a database backup containing a corrupt database.
A second DBCC CHECKDB is performed on the restored database so you will still be notified BUT USE THIS WITH CARE
 
.PARAMETER BackupFolder
Final (Golden) Backup Folder for storing the backups. Be Careful if you are using a source and destination server that you use the full UNC path eg \\SERVER1\BACKUPSHARE\
 
.PARAMETER JobOwner
The account that will own the Agent Jobs - Defaults to sa
 
.PARAMETER UseDefaultFilePaths
Use the instance default file paths for the mdf and ldf files to restore the database if not set will use the original file paths
 
.PARAMETER CategoryName
The Category Name for the Agent Job that gets created defaults to Rationalisation
 
.PARAMETER DBCCErrorFolder
FolderPath for DBCC Error Output - defaults to C:\temp
 
.PARAMETER BackupCompression
The setting for the backup compression for the backup defaults to the default setting for the server but accepts On or Off to override that setting
 
.PARAMETER AllDatabases
Runs the script for every user databases on a server - Useful when decomissioning a server - That would need a DestinationServer set
 
.PARAMETER Force
This switch will continue to perform rest of the actions and will create an Agent Job with DBCCERROR in the name and a Backup file with DBCC in the name
 
.PARAMETER WhatIf
Shows what would happen if the command were to run. No actions are actually performed.
 
.PARAMETER Confirm
Prompts you for confirmation before executing any changing operations within the command.

.EXAMPLE
Remove-SqlDatabaseSafely -SqlServer 'Fade2Black' -Databases RideTheLightning -BackupFolder 'C:\MSSQL\Backup\Rationalised - DO NOT DELETE'
 
For the database RideTheLightning on the server Fade2Black Will perform a DBCC CHECKDB and if there are no errors
backup the database to the folder C:\MSSQL\Backup\Rationalised - DO NOT DELETE. It will then create an Agent Job to restore the database
from that backup. It will drop the database, run the agent job to restore it, perform a DBCC ChECK DB and then drop the database.
 
Any DBCC errors will be written to your documents folder
 
.EXAMPLE
$Databases = 'DemoNCIndex','RemoveTestDatabase'
Remove-SqlDatabaseSafely -SqlServer 'Fade2Black' -Databases $Databases -BackupFolder 'C:\MSSQL\Backup\Rationalised - DO NOT DELETE'
 
For the databases 'DemoNCIndex','RemoveTestDatabase' on the server Fade2Black Will perform a DBCC CHECKDB and if there are no errors
backup the database to the folder C:\MSSQL\Backup\Rationalised - DO NOT DELETE. It will then create an Agent Job for each database
to restore the database from that backup. It will drop the database, run the agent job, perform a DBCC ChECK DB and then drop the database
 
Any DBCC errors will be written to your documents folder
 
.EXAMPLE
Remove-SqlDatabaseSafely -SqlServer 'Fade2Black' -DestinationServer JusticeForAll -Databases RideTheLightning -BackupFolder '\\BACKUPSERVER\BACKUPSHARE\MSSQL\Rationalised - DO NOT DELETE'
 
For the database RideTheLightning on the server Fade2Black Will perform a DBCC CHECKDB and if there are no errors
backup the database to the folder \\BACKUPSERVER\BACKUPSHARE\MSSQL\Rationalised - DO NOT DELETE It will then create an Agent Job on the server
JusticeForAll to restore the database from that backup. It will drop the database on Fade2Black, run the agent job to restore it on JusticeForAll,
perform a DBCC ChECK DB and then drop the database
 
Any DBCC errors will be written to your documents folder
.EXAMPLE
Remove-SqlDatabaseSafely -SqlServer IronMaiden -Databases $Databases -DestinationServer TheWildHearts -DBCCErrorFolder C:\DBCCErrors -BackupFolder z:\Backups -NoDBCCCheck -UseDefaultFilePaths -JobOwner 'THEBEARD\Rob'
 
For the databases $Databases on the server IronMaiden Will NOT perform a DBCC CHECKDB
It will backup the databases to the folder Z:\Backups It will then create an Agent Job on the server with a Job Owner of THEBEARD\Rob
TheWildHearts to restore the database from that backup using the instance default filepaths.
It will drop the database on IronMaiden, run the agent job to restore it on TheWildHearts using the default file paths for the instance, perform
a DBCC ChECK DB and then drop the database
 
Any DBCC errors will be written to your documents folder
 
.EXAMPLE
Remove-SqlDatabaseSafely -SqlServer IronMaiden -Databases $Databases -DestinationServer TheWildHearts -DBCCErrorFolder C:\DBCCErrors -BackupFolder z:\Backups -UseDefaultFilePaths -ContinueAfterDbccError
 
For the databases $Databases on the server IronMaiden will backup the databases to the folder Z:\Backups It will then create an Agent Job
TheWildHearts to restore the database from that backup using the instance default filepaths.
It will drop the database on IronMaiden, run the agent job to restore it on TheWildHearts using the default file paths for the instance, perform
a DBCC ChECK DB and then drop the database
 
If there is a DBCC Error it will continue to perform rest of the actions and will create an Agent Job with DBCCERROR in the name and a Backup file with DBCCError in the name
