Estimate SQL Restore Database Estimated Finish Time

17 July,2012 by Tom Collins

Question: I’ve issued a  RESTORE DATABASE on a 700 GB database. It’s been taking awhile and business users are keen to know the estimate percent complete  and estimate finish time . How can I find out this information?

Answer: Using the SQL Server DMV sys.dm_exec_requests  , assists in estimating the finish time. The percent_complete and estimated_completion columns are useful.

While the RESTORE is running – run the query below without the session_id.

Look for a record with RESTORE COMMAND in the command column.

I’ve included a sample query , which returns a percent complete and estimated completion. Use it for:  BACKUP \ RESTORE, DBCC CHECKDB , DBCC CHECKTABLE,DBCC SHRINKDB , dbcc SHRINKFILE,DBCC INDEXDEFRAG,ALTER INDEX REORGANIZE, ROLLBACK


SELECT session_id,percent_complete,DATEADD(MILLISECOND,estimated_completion_time,CURRENT_TIMESTAMP) Estimated_finish_time,
(total_elapsed_time/1000)/60 Total_Elapsed_Time_MINS ,
DB_NAME(Database_id) Database_Name ,command,sql_handle
FROM sys.dm_exec_requests WHERE session_id=57


It's important to test your RESTORE strategy. Read more on Schrodinger’s backup - A warning for DBAs
