function Install-DbaMaintenanceSolution { <# .SYNOPSIS Download and Install SQL Server Maintenance Solution created by Ola Hallengren (https://ola.hallengren.com) .DESCRIPTION This script will download and install the latest version of SQL Server Maintenance Solution created by Ola Hallengren .PARAMETER SqlInstance The target SQL Server instance .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 The database where Ola Hallengren's solution will be installed. Defaults to master .PARAMETER BackupLocation Location of the backup root directory. If this is not supplied, the default backup directory will be used. .PARAMETER CleanupTime Time in hours, after which backup files are deleted .PARAMETER OutputFileDirectory Specify the output file directory .PARAMETER ReplaceExisting If the objects are already present in the chosen database, we drop and recreate them .PARAMETER LogToTable Log commands to a table .PARAMETER Solution You can choose to install the complete solution (All) or only one of: Backup / IntegrityCheck / IndexOptimize .PARAMETER InstallJobs Create SQL Agent Jobs .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 .NOTES Author: Viorel Ciucu, viorel.ciucu@gmail.com, cviorel.com .LINK http://dbatools.io/Install-DbaMaintenanceSolution .EXAMPLE Install-DbaMaintenanceSolution -SqlInstance RES14224 -Database DBA -CleanupTime 72 Installs Ola Hallengren's Solution objects on RES14224 in the master database. Backups will default to the default Backup Directory. If the Maintenance Solution already exists, the script will be halted. .EXAMPLE Install-DbaMaintenanceSolution -SqlInstance RES14224 -Database DBA -ReplaceExisting -CleanupTime 72 -LogToTable -Solution "Backup" -BackupLocation "Z:\SQLBackup" -InstallJobs .EXAMPLE Install-DbaMaintenanceSolution -SqlInstance RES14224 -Database DBA -BackupLocation "Z:\SQLBackup" -CleanupTime 72 This will create the Ola Hallengren's Solution objects.
