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

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

Answer 3

Add STATS=10 or STATS=1 in backup command.

BACKUP DATABASE [xxxxxx] TO  DISK = N'E:\\Bachup_DB.bak' WITH NOFORMAT, NOINIT,  
NAME = N'xxxx-Complète Base de données Sauvegarde', SKIP, NOREWIND, NOUNLOAD, COMPRESSION,  STATS = 10
GO.

Answer 4

Yes. If you have installed sp_who2k5 into your master database, you can simply run:

sp_who2k5 1,1

The resultset will include all the active transactions. The currently running backup(s) will contain the string "BACKUP" in the requestCommand field. The aptly named percentComplete field will give you the progress of the backup.

Note: sp_who2k5 should be a part of everyone's toolkit, it does a lot more than just this.

Answer 5

I think the best way to find out how your restore or backup progress is by the following query:

USE[master]
GO
SELECT session_id AS SPID, command, a.text AS Query, start_time, percent_complete, dateadd(second,estimated_completion_time/1000, getdate()) as estimated_completion_time 
    FROM sys.dm_exec_requests r CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) a 
        WHERE r.command in ('BACKUP DATABASE','RESTORE DATABASE')
GO

The query above, identify the session by itself and perform a percentage progress every time you press F5 or Execute button on SSMS!
