The Backup - Hours Since Last Differential Backup Alarm becomes active when Spotlight detects that a differential backup of the SQL Server database has never taken place or has not taken place in the last 24 hours.
Differential backups are important for mission-critical databases.
Note: This alarm is not activated for missing backups of the tempdb database.
When this alarm is current:
- Check the date and time of the last backup. You will find this information on the Databases drilldown in the Databases grid. Set the Database View to Backup Status.
- Ensure you have appropriate backups of all necessary databases.
To exclude certain databases from the Backup - Hours Since Last Differential Backup Alarm:

- Select Override the default settings for the alarm.
- In the lower right pane, in Do not raise an alarm for certain values, click the values link to add the name of the database you want excluded.
