SQL-Server: Is there a SQL script that I can use to determine the progress of a SQL Server backup or restore process?

Question

When I backup or restore a database using MS SQL Server Management Studio, I get a visual indication of how far the process has progressed, and thus how much longer I still need to wait for it to finish. If I kick off the backup or restore with a script, is there a way to monitor the progress, or do I just sit back and wait for it to finish (hoping that nothing has gone wrong?)

Edited: My need is specifically to be able to monitor the backup or restore progress completely separate from the session where the backup or restore was initiated.

Answer 1

I found this sample script here that seems to be working pretty well:

SELECT r.session_id,r.command,CONVERT(NUMERIC(6,2),r.percent_complete) AS [Percent Complete],CONVERT(VARCHAR(20),DATEADD(ms,r.estimated_completion_time,GetDate()),20) AS [ETA Completion Time], CONVERT(NUMERIC(10,2),r.total_elapsed_time/1000.0/60.0) AS [Elapsed Min], CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0) AS [ETA Min], CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0/60.0) AS [ETA Hours], CONVERT(VARCHAR(1000),(SELECT SUBSTRING(text,r.statement_start_offset/2, CASE WHEN r.statement_end_offset = -1 THEN 1000 ELSE (r.statement_end_offset-r.statement_start_offset)/2 END) FROM sys.dm_exec_sql_text(sql_handle))) AS [SQL] FROM sys.dm_exec_requests r WHERE command IN ('RESTORE DATABASE','BACKUP DATABASE') 

Answer 2

If you know the sessionID then you can use the following:

SELECT * FROM sys.dm_exec_requests WHERE session_id = 62 

Or if you want to narrow it down:

SELECT command, percent_complete, start_time FROM sys.dm_exec_requests WHERE session_id = 62
