function New-DbaLogShippingPrimaryDatabase { <# .SYNOPSIS New-DbaLogShippingPrimaryDatabase add the primary database to log shipping .DESCRIPTION New-DbaLogShippingPrimaryDatabase will add the primary database to log shipping. This is executed on the primary server. .PARAMETER SqlInstance SQL Server instance. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Database Database to set up log shipping for. .PARAMETER BackupDirectory Is the path to the backup folder on the primary server. .PARAMETER BackupJob Is the name of the SQL Server Agent job on the primary server that copies the backup into the backup folder. .PARAMETER BackupJobID The SQL Server Agent job ID associated with the backup job on the primary server. .PARAMETER BackupRetention Is the length of time, in minutes, to retain the log backup file in the backup directory on the primary server. .PARAMETER BackupShare Is the network path to the backup directory on the primary server. .PARAMETER BackupThreshold Is the length of time, in minutes, after the last backup before a threshold_alert error is raised. The default is 60. .PARAMETER CompressBackup Enables the use of backup compression .PARAMETER ThressAlert Is the length of time, in minutes, when the alert is to be raised when the backup threshold is exceeded. The default is 14,420. .PARAMETER HistoryRetention Is the length of time in minutes in which the history will be retained. The default is 14420. .PARAMETER MonitorServer Is the name of the monitor server. The default is the name of the primary server. .PARAMETER MonitorCredential Allows you to login to enter a secure credential. This is only needed in combination with MonitorServerSecurityMode having either a 0 or 'sqlserver' value. To use: $scred = Get-Credential, then pass $scred object to the -MonitorCredential parameter. .PARAMETER MonitorServerSecurityMode The security mode used to connect to the monitor server. Allowed values are 0, "sqlserver", 1, "windows" The default is 1 or Windows. .PARAMETER ThresholdAlertEnabled Specifies whether an alert will be raised when backup threshold is exceeded. The default is 0. .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. .PARAMETER Silent Use this switch to disable any kind of verbose messages .PARAMETER Force The force parameter will ignore some errors in the parameters and assume defaults. It will also remove the any present schedules with the same name for the specific job. .NOTES Original Author: Sander Stad (@sqlstad, sqlstad.nl) Tags: Log shippin, primary database Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/New-DbaLogShippingPrimaryDatabase .EXAMPLE New-DbaLogShippingPrimaryDatabase -SqlInstance sql1 -Database DB1 -BackupDirectory D:\data\logshipping -BackupJob LSBackup_DB1 -BackupRetention 4320 -BackupShare "\\sql1\logshipping" -BackupThreshold 60 -CompressBackup -HistoryRetention 14420 -MonitorServer sql1 -ThresholdAlertEnabled #> [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = "Low")] param ( [parameter(Mandatory = $true)] [Alias("ServerInstance", "SqlServer")] [object]$SqlInstance, [System.Management.Automation.PSCredential] $SqlCredential, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [object]$Database, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [string]$BackupDirectory, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [string]$BackupJob, [Parameter(Mandatory = $true)] [int]$BackupRetention, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [string]$BackupShare, [int]$BackupThreshold = 60, [switch]$CompressBackup, [int]$ThressAlert = 14420, [int]$HistoryRetention = 14420, [string]$MonitorServer, [ValidateSet(0, "sqlserver", 1, "windows")] [object]$MonitorServerSecurityMode = 1, [System.Management.Automation.PSCredential] $MonitorCredential, [switch]$ThresholdAlertEnabled, [switch]$Silent, [switch]$Force ) #
