Example: Piecemeal Restore of Database (Simple Recovery Model)

Artykuł

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

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.

Online restore of filegroup B.

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

All filegroups are now online.
