Description

This cmdlet will take a backup of the search index to a specified backup location. The cmdlet has to be run in two phases. Phase one will take a backup of what is present in the index at the time that the backup cmdlet is run. Phase two will take a differential backup of what was added to the index after you started the first phase index backup.

Examples

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

$ssa = Get-SPEnterpriseSearchServiceApplication
Backup-SPEnterpriseSearchServiceApplicationIndex -Phase 1 -SearchApplication $ssa -BackupFolder "\\backuphost\backupfolder" -BackupHandleFile "\\backuphost\backupfolder\backuphandle.txt" -Retries 3

This example starts a Phase 1 backup of the search index for the default search application, and stores the backup at the location \\backuphost\backupfolder. The cmdlet stores a handle file backuphandle.txt that is used by the second phase cmdlet.

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

$ssa = Get-SPEnterpriseSearchServiceApplication
Backup-SPEnterpriseSearchServiceApplicationIndex -Phase 1 $ssa -BackupFolder "\\backuphost\backupfolder" -BackupHandleFile "\\backuphost\backupfolder\backuphandle.txt" -Retries 3

This example checks the backup status and progress by re-running the cmdlet for Phase 1.

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

$ssa = Get-SPEnterpriseSearchServiceApplication
Backup-SPEnterpriseSearchServiceApplicationIndex -Phase 2 -SearchApplication $ssa -BackupFolder "\\backuphost\backupfolder" -BackupHandleFile "\\backuphost\backupfolder\backuphandle.txt" -Retries 3

This example starts the Phase 2 of the search index backup by using the same backup location and backup handle file as used for Phase 1. The Search Service Application must be paused before the second phase can be started.

Parameters

-Abort

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	SharePoint Server Subscription Edition

-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.
