Description

The Get-SPBackupHistory cmdlet reads a history of backup and restore operations that have been run. Specifies whether you want to display only the backup history, only the restore history, or all of the history.

For permissions and the most current information about Windows PowerShell for SharePoint Products, see the online documentation at SharePoint Server Cmdlets.

Examples

------------------EXAMPLE 1-----------------

Get-SPBackupHistory -Directory \\file_server\share\Backup

This example returns all farm backup and restore operations that have been run for the \\file_server\share\Backup directory.

------------------EXAMPLE 2-----------------

Get-SPBackupHistory -Directory C:\Backup -ShowBackup

This example returns all of the farm backup operations that have been run for the C:\Backup directory.

------------------EXAMPLE 3-----------------

(Get-SPBackupHistory -Directory C:\Backup -ShowBackup)[0].SelfId | Restore-SPFarm -Directory C:\Backup -RestoreMethod overwrite

This example gets all of the farm backup operations that have been run for the C:\Backup directory, finds the most recent backup, and then passes its backup GUID to the Restore-SPFarm cmdlet. The Restore-SPFarm cmdlet will then perform an overwrite restore from that backup package.

Parameters

-AssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.
