The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 8: Backup and Restore for FILESTREAM Databasesprocess for such databases will be a time- and resource-consuming process. A typicalbackup scheme might consist of weekly full backups interspersed with nightly differentialbackups (plus transaction log backups, as required).Again, the behavior of differential backups is the same with FILESTREAM as withnon-FILESTREAM databases. Listing 8-3 inserts a new row into the NorthPole databaseand then captures a differential backup.-- Insert another row into the tableUSE NorthPoleGOINSERT INTO Items (ItemID, ItemNumber, ItemDescription, ItemImage)SELECTNEWID(), 'MS1002', 'Microsoft Mouse 2',CAST(bulkcolumn AS VARBINARY(MAX))FROM OPENROWSET(BULK 'C:\ArtOfFS\Demos\Images\MicrosoftMouse.jpg', SINGLE_BLOB) AS x-- Take a differential backupUSE masterGOBACKUP DATABASE NorthPoleTO DISK = 'C:\ArtOfFS\Demos\Chapter8\bak\NorthPole_Diff.bak'WITH DIFFERENTIALGOListing 8-3:Capturing a differential database backup.Transaction log backupsA transaction log backup captures every record in the log that has been generated sincethe last log backup. We can combine these log backups with full (and any differential)backups to restore a database to any point in time before the last log backup was taken,assuming we have an unbroken chain of log files, taken after the relevant full backup.316
