EV Backups in System Status

The Enterprise Vault System Status might sometimes show entries like this relating to backups (or lack of them):

How does Enterprise Vault get this information?

Well the information is stored in SQL system tables, and can be read by anyone - it's just read by System Status and then made to look nice.  Here's an example of one such script that will give you output showing when databases were backed up:

SELECT sdb.Name AS DatabaseName,
COALESCE(CONVERT(VARCHAR(12), MAX(bus.backup_finish_date),101),'-') AS LastBackUpTime
FROM sys.sysdatabases sdb
LEFT OUTER JOIN msdb.dbo.backupset bus ONbus.database_name = sdb.name
GROUP BY sdb.Name
