Checking the progress of a backup or restore

By | December 22, 2013

With SQL Server’s powerful DMV’s it’s easy to monitor the progress of a SQL Backup or restore operation, but you can also use it to see the current running queries on your SQL instance. In this case you should delete the last WHERE command in the query. Note that the percent_complete column is not updated for all T-SQL commands.

SELECT command,
s.text,
start_time,
percent_complete,
CAST(((DATEDIFF(s,start_time,GetDate()))/3600) as varchar) + ' hour(s), '
+ CAST((DATEDIFF(s,start_time,GetDate())%3600)/60 as varchar) + 'min, '
+ CAST((DATEDIFF(s,start_time,GetDate())%60) as varchar) + ' sec' as running_time,
CAST((estimated_completion_time/3600000) as varchar) + ' hour(s), '
+ CAST((estimated_completion_time %3600000)/60000 as varchar) + 'min, '
+ CAST((estimated_completion_time %60000)/1000 as varchar) + ' sec' as est_time_to_go,
dateadd(second,estimated_completion_time/1000, getdate()) as est_completion_time
FROM sys.dm_exec_requests r
CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) s
WHERE r.command in ('RESTORE DATABASE', 'BACKUP DATABASE', 'RESTORE LOG', 'BACKUP LOG')
