The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 7: FILESTREAM Database AdministrationDatabase Publishing WizardThe current version of Database Publishing Wizard can be downloaded from: http://brurl.com/fs23.The Database Publishing Wizard allows us to publish a SQL Server 2008 database to aSQL Server 2008 or 2005 database. When publishing from SQL Server 2008 to 2005,FILESTREAM columns will be created as VARBINARY(MAX) columns. We cannot publisha SQL Server 2008 database with FILESTREAM columns for deployment to a SQL Server2000 instance.SummaryThis chapter walked through quite an array of database administration topics that arerelevant to people managing FILESTREAM databases. Here's a brief summary of whatwe covered.• How to detach and attach FILESTREAM databases and, in the process, move theFILESTREAM files to a new location.• The behavior of FILESTREAM data under the transaction isolation levels.• How the database recovery model of the database affects the way the garbage collectorsteps in and removes the garbage files. We also looked at the FILESTREAM tombstonetable, which keeps track of the garbage files; the garbage collector uses this table toidentify the files to be removed.• Why it is not recommended that you touch the FILESTREAM data files on the NTFSfolder directly, and why all access to the FILESTREAM data should be made throughSQL Server only. Deleting files from the FILESTREAM data container or creating newfiles in the FILESTREAM data container can cause corruption in the database.310
