#ValidationTags#Messaging,FlowControl,Pipeline# 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 IgnoreCopyOnly If set, Get-DbaBackupHistory will ignore CopyOnly backups .PARAMETER Force Returns a boatload of information, the way SQL Server returns it .PARAMETER Since Datetime object used to narrow the results to a date .PARAMETER Last Returns last entire chain of full, diff and log backup sets - starting backwards from most recent log .PARAMETER LastFull Returns last full backup set .PARAMETER LastDiff Returns last differential backup set .PARAMETER LastLog Returns last log backup set .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 .PARAMETER Silent Replaces user friendly yellow warnings with bloody red exceptions of doom! Use this if you want the function to throw terminating errors you want to catch. .PARAMETER Databases Return backup information for only specific databases. These are only the databases that currently exist on the server. .EXAMPLE Get-DbaBackupHistory -SqlServer sqlserver2014a Returns server name, database, username, backup type, date for all backups databases on sqlserver2014a. This may return a ton of rows; consider using filters that are included in other examples. .EXAMPLE $cred = Get-Credential sqladmin Get-DbaBackupHistory -SqlServer sqlserver2014a -SqlCredential $cred Does the same as above but logs in as SQL user "sqladmin" .EXAMPLE Get-DbaBackupHistory -SqlServer sqlserver2014a -Databases db1, db2 -Since '7/1/2016 10:47:00' Returns backup information only for databases db1 and db2 on sqlserve2014a since July 1, 2016 at 10:47 AM. .EXAMPLE Get-DbaBackupHistory -SqlServer sql2014 -Databases AdventureWorks2014, pubs -Force | Format-Table Returns information only for AdventureWorks2014 and pubs, and makes the output pretty .EXAMPLE Get-DbaBackupHistory -SqlServer sql2014 -Databases AdventureWorks2014 -Last Returns information about the most recent full, differential and log backups for AdventureWorks2014 on sql2014 .EXAMPLE Get-DbaBackupHistory -SqlServer sql2014 -Databases AdventureWorks2014 -LastFull Returns information about the most recent full backup for AdventureWorks2014 on sql2014 .EXAMPLE Get-SqlRegisteredServerName -SqlServer sql2016 | Get-DbaBackupHistory Returns database backup information for every database on every server listed in the Central Management Server on sql2016 .EXAMPLE Get-DbaBackupHistory -SqlServer sqlserver2014a, sql2016 -Force Lots of detailed information for all databases on sqlserver2014a and sql2016. .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.
