Function Get-DbaBackupHistory { <# .SYNOPSIS Returns backup history details for databases on a SQL Server .DESCRIPTION Returns backup history details for some or all databases on a SQL Server. You can even get detailed information (including file path) for latest full, differential and log files. Reference: http://www.sqlhub.com/2011/07/find-your-backup-history-in-sql-server.html .PARAMETER SqlServer The SQL Server that you're connecting to. .PARAMETER Credential Credential object used to connect to the SQL Server as a different user .PARAMETER Databases Return backup information for only specific databases. These are only the databases that currently exist on the server. .PARAMETER Since Datetime object used to narrow the results to a date .PARAMETER Force Returns a boatload of information, the way SQL Server returns it .PARAMETER Last Returns last full, diff and log backup sets .PARAMETER LastFull Returns last full backup set .PARAMETER LastDiff Returns last differential backup set .PARAMETER LastLog Returns last log backup set .PARAMETER IgnoreCopyOnly If set, Get-DbaBackupHistory will ignore CopyOnly backups .PARAMETER Raw By default the command will group mediasets (striped backups across multiple files) into a single return object. If you'd prefer to have an object per backp file returned, use this switch .NOTES Tags: Storage, DisasterRecovery, Backup dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
