Move-SPBlobStorageLocation

 

Applies to: SharePoint Server 2010, SharePoint Foundation 2010

Topic Last Modified: 2010-02-15

Copies a Windows SharePoint Services 3.0 content database by using Remote BLOB Storage (RBS).

Move-SPBlobStorageLocation [-SourceDatabase] <String> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-DestinationDatabase <String>] [-DestinationDataSourceInstance <String>] [-Dir <String>] [-VerboseMod <$true | $false>] [-WhatIf [<SwitchParameter>]]

Use the Move-SPBlobStorageLocation cmdlet to copy a Windows SharePoint Services 3.0 content database into a Microsoft SQL Server 2008 with Service Pack 1 (SP1) and Cumulative Update 2 database instance by using Remote BLOB Storage (RBS). The database size limitation for SQL Server 2008 with SP1 and Cumulative Update 2 is 4 gigabyes (GB). If a Windows SharePoint Services 3.0 content database is greater than 4 GB, the database cannot be copied directly into a SQL Server 2008 with SP1 and Cumulative Update 2 database instance. The Move-SPBlobStorageLocation cmdlet uses the advantage of RBS and copies databases larger than 4 GB. RBS stores the data on the local hard disk and keeps the links to the data in the database, which results in a smaller database.

 

Parameter Required Type Description

SourceDatabase

Required

System.String

Specifies the name of the Windows Internal Database.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

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.

noteNote
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.

Confirm

Optional

System.Management.Automation.SwitchParameter

Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters

DestinationDatabase

Optional

System.String

Specifies the name of the migrated database. If the DestinationDatabase parameter is not specified, the SourceDatabase parameter is used.

DestinationDataSourceInstance

Optional

System.String

Specifies the destination database instance name. The value in the SourceDatabase parameter is migrated to this instance. The database instance name should be Microsoft SQL Server 2008 with Service Pack 1 (SP1) and Cumulative Update 2 version or higher. If the DestinationDataSourceInstance parameter is not specified, the local host name is used.

Dir

Optional

System.String

Used for all disk operations, including storing temporary backups and database (.mdf) files of a migrated database. If the Dir parameter is not specified, a default directory of the destination SQL Server instance is used. The free space in this directory should be at least two times the size of the source database.

VerboseMod

Optional

System.Boolean

Generates verbose log output to be displayed in the Command Prompt window. If the VerboseMod parameter is not specified, no output is displayed.

WhatIf

Optional

System.Management.Automation.SwitchParameter

Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters

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

Move-SPBlobStorageLocation WSS_Content

This example copies the content database named WSS_Content from the Windows Internal Database to the same database name in Microsoft SQL Server 2008 Express by using RBS.

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

Move-SPBlobStorageLocation WSS_Content -DestinationDatabase WSS_V4_Content -BackupDatabase WSSBackupDB -VerboseMod:$true

This example copies the content database named WSS_Content from the Windows Internal Database to a database in SQL Server 2008 Express. The name of the new database will be WSS_V4_Content. During the move, the backup file name will be WSSBackupDB. The output of this command displays log information to the Command Prompt window.
