Chapter 8: Backup and Restore for FILESTREAM DatabasesWhen the backup has been restored, go to the FILESTREAM data container and youwill see 101 files instead of just the 1 that you would normally expect to see. It is quitesurprising to see that all the garbage files came along with the backup, and they all gotrestored in the new location.The garbage files unnecessarily increase the backup time and size, and increase the diskspace requirements on the target location. My tests showed that a transaction log backupfollowed by a full backup on the target database clears the garbage files the next time thegarbage collector runs.SummaryWe have seen that taking a backup of a FILESTREAM database is no different frombacking up a non-FILESTREAM database. However, a restore operation may need a littlebit more attention when restoring to a different database because you have to specify thelocation to which the FILESTREAM data is to be restored. In addition, you need to makesure that the FILESTREAM feature is enabled on the target database. SQL Server supportspoint-in-time recovery of FILESTREAM-enabled databases and this chapter presented anexample to demonstrate this feature.SQL Server allows the creation of full file backups of FILESTREAM databases that do notinclude the FILESTREAM filegroups. When such a backup is restored, all the relationaldata will be accessible. If you attempt to access the FILESTREAM data, SQL Server willgenerate an error.The backup of a FILESTREAM database includes the garbage and orphaned files that arepresent in the FILESTREAM data container at the time of the backup. These files will berestored on the target location when the database is restored.328
Chapter 9: Investigating FILESTREAMDatabasesIn the previous two chapters, we examined FILESTREAM database administration insome detail. To complete the discussion, we examine here our various options forinvestigating the FILESTREAM database and configuration metadata.This chapter focuses on exposing a number of FILESTREAM-related system catalog views,along with a number of useful queries that help you to retrieve various valuable pieces ofinformation about the FILESTREAM configuration. We also take a brief look at some ofthe in-depth information available from the FILESTREAM-related Dynamic ManagementViews (DMVs), and the available wait types that might help you troubleshoot variousFILESTREAM performance issues.Relevant System Catalog ViewsSQL Server has a number of FILESTREAM-related system views that we can use to findinformation about FILESTREAM tables and columns.We'll briefly review the system views that contain metadata relevant to FILESTREAMcolumns, and then take a look at some useful queries based on these views, which cangive us such information as the location of the FILESTREAM data container, the namesof all tables in a database that contain FILESTREAM columns, and so on.329
