function Get-DbaRestoreHistory { <# .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 Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $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 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. .NOTES Tags: DisasterRecovery, Backup, Restore, Databases 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/Get-DbaRestoreHistory .EXAMPLE Get-DbaRestoreHistory -SqlInstance sql2016 Returns server name, database, username, restore type, date for all restored databases on sql2016. .EXAMPLE Get-DbaRestoreHistory -SqlInstance sql2016 -Database db1, db2 -Since '7/1/2016 10:47:00' Returns restore information only for databases db1 and db2 on sql2016 since July 1, 2016 at 10:47 AM. .EXAMPLE Get-DbaRestoreHistory -SqlInstance sql2014, sql2016 -Exclude db1 Lots of detailed information for all databases except db1 on sql2014 and sql2016. .EXAMPLE Get-DbaRestoreHistory -SqlInstance sql2014 -Database AdventureWorks2014, pubs | Format-Table Adds From and To file information to output, returns information only for AdventureWorks2014 and pubs, and formats the data as a table. .EXAMPLE Get-DbaRegisteredServer -SqlInstance sql2016 | Get-DbaRestoreHistory Returns database restore information for every database on every server listed in the Central Management Server on sql2016. #> [CmdletBinding()] Param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [Alias("Credential")] [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [datetime]$Since, [switch]$Force, [switch]$Last ) begin { Test-DbaDeprecation -DeprecatedOn "1.0.0.0" -EnableException:$false -Parameter 'Force' if ($Since -ne $null) { $Since = $Since.ToString("yyyy-MM-dd HH:mm:ss") } } process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential if ($server.VersionMajor -lt 9) { Write-Warning "SQL Server 2000 not supported." continue } $computername = $server.NetName $instancename = $server.ServiceName $servername = $server.DomainInstanceName if ($force -eq $true) { $select = "SELECT '$computername' AS [ComputerName], '$instancename' AS [InstanceName], '$servername' AS [SqlInstance], * " } else { $select = "SELECT '$computername' AS [ComputerName], '$instancename' AS [InstanceName], '$servername' AS [SqlInstance], rsh.destination_database_name AS [Database], --rsh.restore_history_id as RestoreHistoryID, rsh.user_name AS [Username], CASE WHEN rsh.restore_type = 'D' THEN 'Database' WHEN rsh.restore_type = 'F' THEN 'File' WHEN rsh.restore_type = 'G' THEN 'Filegroup' WHEN rsh.restore_type = 'I' THEN 'Differential' WHEN rsh.restore_type = 'L' THEN 'Log' WHEN rsh.restore_type = 'V' THEN 'Verifyonly' WHEN rsh.restore_type = 'R' THEN 'Revert' ELSE rsh.restore_type END AS [RestoreType], rsh.restore_date AS [Date], ISNULL(STUFF((SELECT ', ' + bmf.physical_device_name FROM msdb.dbo.backupmediafamily bmf WHERE bmf.media_set_id = bs.media_set_id FOR XML PATH('')), 1, 2, ''), '') AS [From], ISNULL(STUFF((SELECT ', ' + rf.destination_phys_name FROM msdb.dbo.restorefile rf WHERE rsh.restore_history_id = rf.restore_history_id FOR XML PATH('')), 1, 2, ''), '') AS [To], bs.first_lsn, bs.last_lsn, bs.checkpoint_lsn, bs.database_backup_lsn " } $from = " FROM msdb.dbo.restorehistory rsh INNER JOIN msdb.dbo.backupset bs ON rsh.backup_set_id = bs.backup_set_id" if ($ExcludeDatabase -or $Database -or $Since -or $last) { $where = " WHERE " } $wherearray = @() if ($ExcludeDatabase) { $dblist = $ExcludeDatabase -join "','" $wherearray += " destination_database_name not in ('$dblist')" } if ($Database) { $dblist = $Database -join "','" $wherearray += "destination_database_name in ('$dblist')" } if ($Since -ne $null) { $wherearray += "rsh.restore_date >= '$since'" } if ($last) { $wherearray += "rsh.backup_set_id in (select max(backup_set_id) from msdb.dbo.restorehistory group by destination_database_name )" } if ($where.length -gt 0) { $wherearray = $wherearray -join " and " $where = "$where $wherearray" } $sql = "$select $from $where" Write-Debug $sql $results = $server.ConnectionContext.ExecuteWithResults($sql).Tables.Rows if ($last) { $ga = $results | group-Object database $tmpres = @() $ga | foreach-Object { $tmpres += $_.Group | Sort-Object -Property RESTORE_DATE -Descending | Select-Object -first 1 } $results = $tmpres } $results | Select-DefaultView -Exclude first_lsn, last_lsn, checkpoint_lsn, database_backup_lsn, RowError, RowState, Table, ItemArray, HasErrors } catch { Write-Warning $_ Write-Exception $_ continue } } } } |
