Check database back up set capacity

Sometimes you need to check your back up files to do some maintenance actions for it, here's the script you can use.

SELECT CONVERT(VARCHAR(10), backup_start_date, 111) [Backup Date]
, backup_size/1024000 [Size In MB]
FROM msdb..backupset
WHERE database_name = 'Your DB Name'
and type = 'd'
ORDER BY backup_start_date DESC
COMPUTE SUM(backup_size/1024000)
