How to find SQL database Backup or Restore Percentage query

Monitoring Estimated Completion Times for Backup, Restore, and DBCC Commands in SQL Server In the world of database administration, long-running operations like backups, restores, and DBCC commands can leave us staring at the screen, wondering how much longer they’ll take. To alleviate this uncertainty, I’ve got you covered with a script that monitors the progress and provides estimated completion times for these critical tasks. 

 [code type="SQL"] SELECT @@servername[Servername],getdate() [TimeNow],command, r.session_id, r.blocking_session_id, 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','RESTORE LOG','BACKUP DATABASE', 'BACKUP LOG','DbccSpaceReclaim','DbccFilesCompact')[/code] 

This code can be executed SQL server 2008 or later.
