Before you can recover objects or execute a SELECT statement, you must read the backup file to create an index of restorable objects. The index is an .lsm file. During the backup process the .lsm file is created in the temp directory and attached to the backup file after the backup is completed.
Notes: |
To read the backup files
Select the Object Level Recovery pane (CTRL+3).
Select Object Level Recovery Wizard.

For tables, you can also include constraints, indexes, and triggers in the script by selecting the appropriate options on the Object Level Recovery tab in Object Level Recovery options. You can script more than one object, and scripted objects have a small scroll icon beside them in the objects grid. To view all of the scripts in the script preview, click the Select Scripted button in the Object Level Recovery ribbon menu.

You can only preview the data of one table at a time, and the previewed table has a small chart icon beside it in the objects grid.
