#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaDbSnapshot { <# .SYNOPSIS Get database snapshots with details .DESCRIPTION Retrieves the list of database snapshot available, along with their base (the db they are the snapshot of) and creation time .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER SqlCredential Credential object used to connect to the SQL Server as a different user .PARAMETER Database Return information for only specific databases .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER Snapshot Return information for only specific snapshots .PARAMETER ExcludeSnapshot The snapshot(s) to exclude - this list is auto-populated from the server .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: Snapshot Author: Simone Bizzotto (@niphlod) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDbSnapshot .EXAMPLE PS C:\> Get-DbaDbSnapshot -SqlInstance sqlserver2014a Returns a custom object displaying Server, Database, DatabaseCreated, SnapshotOf, SizeMB, DatabaseCreated .EXAMPLE PS C:\> Get-DbaDbSnapshot -SqlInstance sqlserver2014a -Database HR, Accounting Returns information for database snapshots having HR and Accounting as base dbs .EXAMPLE PS C:\> Get-DbaDbSnapshot -SqlInstance sqlserver2014a -Snapshot HR_snapshot, Accounting_snapshot Returns information for database snapshots HR_snapshot and Accounting_snapshot #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [Alias("Credential")] [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [object[]]$Snapshot, [object[]]$ExcludeSnapshot, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { Write-Message -Level Verbose -Message "Connecting to $instance" try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 9 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $dbs = $server.Databases | Where-Object DatabaseSnapshotBaseName if ($Database) { $dbs = $dbs | Where-Object { $Database -contains $_.DatabaseSnapshotBaseName } } if ($ExcludeDatabase) { $dbs = $dbs | Where-Object { $ExcludeDatabase -notcontains $_.DatabaseSnapshotBaseName } } if ($Snapshot) { $dbs = $dbs | Where-Object { $Snapshot -contains $_.Name } } if (!$Snapshot -and !$Database) { $dbs = $dbs | Where-Object IsDatabaseSnapshot -eq $true | Sort-Object DatabaseSnapshotBaseName, Name } if ($ExcludeSnapshot) { $dbs = $dbs | Where-Object { $ExcludeSnapshot -notcontains $_.Name } } foreach ($db in $dbs) { try { $BytesOnDisk = $db.Query("SELECT SUM(BytesOnDisk) AS BytesOnDisk FROM fn_virtualfilestats(DB_ID(),NULL) S JOIN sys.databases D on D.database_id = S.dbid", $db.Name) Add-Member -Force -InputObject $db -MemberType NoteProperty -Name ComputerName -value $server.ComputerName Add-Member -Force -InputObject $db -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $db -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName Add-Member -Force -InputObject $db -MemberType NoteProperty -Name DiskUsage -value ([dbasize]($BytesOnDisk.BytesOnDisk)) Select-DefaultView -InputObject $db -Property ComputerName, InstanceName, SqlInstance, Name, 'DatabaseSnapshotBaseName as SnapshotOf', CreateDate, DiskUsage } catch { Stop-Function -Message "Failure" -ErrorRecord $_ -Target $db -Continue } } } } end { Test-DbaDeprecation -DeprecatedOn "1.0.0" -Alias Get-DbaDatabaseSnapshot } } |
