Example: Piecemeal Restore of Database (Simple Recovery Model)

Applies to: SQL Server

A piecemeal restore sequence restores and recovers a database in stages at the filegroup level, starting with the primary and all read/write, secondary filegroups.

In this example, database adb is restored to a new computer after a disaster. The database is using the simple recovery model. Before the disaster, all the filegroups are online. Filegroups A and C are read/write, and filegroup B is read-only. Filegroup B became read-only before the most recent partial backup, which contains the primary filegroup and the read/write secondary filegroups, A and C. After filegroup B became read-only, a separate file backup of filegroup B was taken.

Restore Sequences

1. Partial restore of the primary and filegroups A and C.

   RESTORE DATABASE adb FILEGROUP='A',FILEGROUP='C'   
      FROM partial_backup   
      WITH PARTIAL, RECOVERY;  
   
   

   At this point, the primary and filegroups A and C are online. All files in filegroup B are recovery pending, and the filegroup is offline.

2. Online restore of filegroup B.

   RESTORE DATABASE adb FILEGROUP='B' FROM backup WITH RECOVERY;  
   
   

   All filegroups are now online.
