Calculating total backup size of all database on a SQL Server

Sometime we need to calculate what is the total size of all backups of all databases hosted on a SQL Server instance. In that case, please use below code. Note: This code will calculate total size of full backups of all databases hosted on the SQL Server instance in GB and MB . However you may change the combination of device_type and type value to suit your specific query. use msdb go /* Please change device_type and backupset type combination as you need. backupmediafamily device_type 2 = File 5 = Tape backupset type L = Log I = Differential D = Full */ SELECT       ( SUM ( backup_size ) + SUM ( 1536 )) / 1024 / 1024 As MBs ,       ( SUM ( backup_size ) + SUM ( 1536 )) / 1024 / 1024 / 1024 As GBs FROM       backupset INNER JOIN (       SELECT             database_name ,             MAX ( backup_start_date ) as LastFullBackupDate       FROM             backupset       WHERE             media_set_id IN

How to take count rows of all tables in a database?
