Find out time left in backup/restore – SQL Server

Sometimes you want to find out how soon the backup or restore will finish. We can use sys.dm_exec_requests table to find out that information. sys.dm_exec_requests displays all request waiting to be executed or are currently executing. Cross joining the sys.dm_exec_sql_text table will give the query text in the queue. The time shown in estimated_completion_time are estimates hence estimated in the name, but relatively accurate and gives the user a general idea of how long the backup or restore will take.

Query about full backup:

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’)


Query about log backup:

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 LOG’)


Query about restore job:

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 (‘RESTORE DATABASE’)
