SharePoint 承擔著文件管理的工作，默認都是將它們以BLOB的數據形式存儲在內容數據庫當中；當文件大時，就很容易導致數據庫容量被這些BLOB數據所快速消耗，而且頻繁地對這些大數據量的BLOB數據進行讀寫訪問，很容易在SQL端造成性能瓶頸。 繼MOSS2007之后，SharePoint2010和2013可以使用SQL Server 2008及其以上版本提供的Remote Blob Storage (RBS) 這一新特性，可以將BLOB數據存儲在文件系統當中或者是存儲在其他專門用于存儲BLOB數據的服務器上面。

示例采用sql server 2012 數據庫。系統 windows 2008R2 SP1 。

啟用FilesStream：打開Sql server 2012 的“配置工具”，然后打開“Sql Server 配置管理器”,選擇“Sql Server 服務”，找到“SQL Server (MSSQLSREVER)”,右擊“屬性”，找到“FILESSTREAM”欄，操作如圖：

通過SQL Server Configuration Manager，啟用數據庫的FileStream特性。然后通過以下語句，設置fielstream的可訪問級別： EXEC sp_configure filestream_access_level, 2 RECONFIGURE

為SharePoint的內容數據庫加增加主密鑰 use [WSS_Content] if not exists (select * from sys.symmetric_keys where name = N'##MS_DatabaseMasterKey##') create master key encryption by password = N'輸入密碼'

為該內容數據庫增加FILESTREAM文件組和文件

?

use [WSS_Content] if not exists (select groupname from sysfilegroups where groupname=N'RBSFilestreamProvider') alter database [WSS_Content] add filegroup RBSFilestreamProvider contains filestream use [WSS_Content] alter database [WSS_Content] add file (name = RBSFilestreamFile, filename = 'c:\blobstore') to filegroup RBSFilestreamProvider

?

安裝RBS：可通過直接執行RBS_X64.msi文件來安裝程序，官方下載Sql Server2013?RBS.msi

通過下面語句檢查是否安裝成功select * from dbo.sysobjects where name like 'rbs%'

啟用RBS：

?

$cdb = Get-SPContentDatabase "WSS_Content"$rbss = $cdb.RemoteBlobStorageSettings $rbss.Installed() $rbss.Enable() $pvdName = $rbss.GetProviderNames()[0] $rbss.SetActiveProviderName($pvdName)$rbss.Migrate()//該命令可以將SharePoint內容數據庫中原有的BLOB遷移到文件系統中$rbss.MinimumBlobStorageSize = 1048000 //該命令用于設置存于文件系統中的文件最小值，當文件小于該值的時候，將還是照常保存在數據庫中。$cdb.Update()

?

垃圾回收機制 ??這篇文章已經說得很好了，可以點擊閱讀

我強調幾點：

通常我們刪除文檔，并非真的刪除，而是保存在SharePoint回收站里，回收站有兩層，一層是用戶操作，可以刪除或者還原，跟PC 電腦差不多；第二層是網站集回收站，一般需要管理員才能操作，這層刪除后，文件就不能通過sharepoint 還原了。

垃圾回收是一個持續緩慢的過程，可以隔段時間查看存放文件的文件夾大小來判斷。

卸載RMS

SharePoint中卸載

?

$cdb=Get-SPContentDatabase <ContentDbName>$rbs=$cdb.RemoteBlobStorageSettings$rbs.GetProviderNames()$rbs.SetActiveProviderName("")$rbs.Migrate()$rbs.Disable()

?

?

管理員方式運行CMD，啟動回收 C:\Program Files\Microsoft SQL Remote Blob Storage 11.0\Maintainer\Microsoft.Data.SqlRemoteBlobs.Maintainer.exe" -connectionstringname RBSMaintainerConnection -operation GarbageCollection ConsistencyCheck ConsistencyCheckForStores -GarbageCollectionPhases rdo -ConsistencyCheckMode r -TimeLimit 120

?

點擊RBS.msi安裝文件以卸載RBS

在數據庫中刪除RBS exec mssqlrbs.rbs_sp_uninstall_rbs 0ALTER TABLE [mssqlrbs_filestream_data_1].[rbs_filestream_configuration] DROP column [filestream_value]ALTER TABLE [mssqlrbs_filestream_data_1].[rbs_filestream_configuration] SET (FILESTREAM_ON = "NULL")

?

現在你可以刪除文件和文件流filegroup: ALTER DATABASE yourdbname Remove file RBSFilestreamFile;ALTER DATABASE yourdbname REMOVE FILEGROUP RBSFilestreamProvider;

Some question about RMB :

QUS:I?have other web servers, app servers and db servers, do i need to install the rbs.msi exe on every other server in the farm , or just only the web servers and the app servers. Such as do we run that msiexec command on each server.
ANS: Best recommend is to install on all the servers

QUS:Also how does rbs work for all migrated sites or existing sites which have documents already stored.? So if we enable rbs for these sites and for files over 5 mb, would that apply to only new uploaded files over 5mb, or will apply to also already stored over 5mb files.??
ANS:?
For newly created docs no issue, docs over 5MB would automatically move
For previous docs, run below commands once you set the "minimum blob storage"
???? $cdb = Get-SPContentDatabase –WebApplication <URL>
?????$rbss = $cdb.RemoteBlobStorageSettings
?????$rbss.Migrate()

QUS:Also does shredded storage impact the files sizes been uploaded as while, such if we configure files to be uploaded over 5 mb, will this apply to the files over this limit or does the files have to be much larger than 5 MB, such 8 or 9 mb have the rbs applied to them.
