#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaDbRestoreHistory { <# .SYNOPSIS Returns restore history details for databases on a SQL Server. .DESCRIPTION By default, this command will return the server name, database, username, restore type, date, from file and to files. Thanks to https://www.mssqltips.com/SqlInstancetip/1724/when-was-the-last-time-your-sql-server-database-was-restored/ for the query and https://sqlstudies.com/2016/07/27/when-was-this-database-restored/ for the idea. .PARAMETER SqlInstance Specifies the SQL Server instance(s) to operate on. Requires SQL Server 2005 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server. .PARAMETER Since Specifies a datetime to use as the starting point for searching backup history. .PARAMETER Force Deprecated. .PARAMETER Last If this switch is enabled, the last restore action performed on each database is returned. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: DisasterRecovery, Backup, Restore Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDbRestoreHistory .EXAMPLE PS C:\> Get-DbaDbRestoreHistory -SqlInstance sql2016 Returns server name, database, username, restore type, date for all restored databases on sql2016. .EXAMPLE PS C:\> Get-DbaDbRestoreHistory -SqlInstance sql2016 -Database db1, db2 -Since '2016-07-01 10:47:00' Returns restore information only for databases db1 and db2 on sql2016 since July 1, 2016 at 10:47 AM. .EXAMPLE PS C:\> Get-DbaDbRestoreHistory -SqlInstance sql2014, sql2016 -Exclude db1 Returns restore information for all databases except db1 on sql2014 and sql2016. .EXAMPLE PS C:\> $cred = Get-Credential sqladmin PS C:\> Get-DbaDbRestoreHistory -SqlInstance sql2014 -Database AdventureWorks2014, pubs -SqlCredential $cred | Format-Table Returns database restore information for AdventureWorks2014 and pubs database on sql2014, connects using SQL Authentication via sqladmin account.
