you can select all Column (*) to see all information

********************************Check FULL abckup history************************************

SELECT database_name,backup_start_date,type,recovery_model,server_name,machine_name,is_password_protected

FROM msdb.dbo.backupset where Type=‘D’ ORDER BY backup_set_id DESC

GO

********************************Check DIFF abckup history************************************

SELECT database_name,backup_start_date,type,recovery_model,server_name,machine_name,is_password_protected

FROM msdb.dbo.backupset where Type=‘i’

ORDER BY backup_set_id DESC

********************************Check LOG abckup history************************************

SELECT

How to Delete your backup history:-

we can make delete for all backup history for any database by this Code

exec MSDB.DBO.sp_delete_database_backuphistory ‘Database name’

So this Code Delete history to the backup but for one database one by one so i will make Cursore to loop on all Server to get all database name then Delete the backup history for all Database

set ANSI_NULLSON

set QUOTED_IDENTIFIERON

go

Create PROC[dbo].DeletebackupHistory

AS

BEGIN

DECLARE @DB Nvarchar(50)

DECLARE GetDB CURSOR FOR

Select Name from Sys.Databases Where database_id> 4 and state_desc=‘ONLINE’

OPEN GetDB

FETCH NEXT FROM GetDB INTO @DB

WHILE @@FETCH_STATUS= 0

BEGIN

—-Delete backup history

exec MSDB.DBO.sp_delete_database_backuphistory @db

——————————-

FETCH NEXT FROM GetDB

INTO @DB

END— FETCH WHILE

CLOSE GetDB

DEALLOCATE GetDB

END
