SQL Server2008查询备份进度

方法一：
select command
,percent_complete
,running_time=convert(varchar,((datediff(s,start_time,getdate()))/3600))+' hour, '
+convert(varchar,((datediff(s,start_time,getdate()))%3600/60))+' min, '
+convert(varchar,((datediff(s,start_time,getdate()))%60))+' sec'
,est_time_to_go=convert(varchar,(estimated_completion_time/1000)/3600)+' hour, '
+convert(varchar,(estimated_completion_time/1000)%3600/60)+' min, '
+convert(varchar,(estimated_completion_time/1000)%60)+' sec'
,start_time=convert(char(16),start_time,120)
,est_completion_time=convert(char(16),dateadd(second,estimated_completion_time/1000,getdate()),120)

,s.text
from sys.dm_exec_requests r
cross apply sys.dm_exec_sql_text(r.sql_handle) s
where r.command in ('BACKUP DATABASE','RESTORE DATABASE','BACKUP LOG','RESTORE LOG','DbccFilesCompact','DbccSpaceReclaim')
