Database dumps and restore may fill up MSDB database (152354)

WORKAROUND

In SQL Server 6.5, the following tables have been added to the MSDB database to aid in maintaining backup information:

sysbackupdetail : Specifies a summary of the devices used to backup (dump).
sysbackuphistory : Specifies a summary of each backup operation (dump).
sysrestoredetail : Specifies a summary of the devices used to restore (load).
sysrestorehistory : Specifies a summary of each restore operation (load).

SQL Server automatically maintains a complete online backup and restore history in the MSDB database. This information includes who performed the backup, when it was done, and which devices or files it is stored on.

The System Administrator has to monitor these tables to delete old entries in these tables to make sure that MSDB database does not fill up.

The following stored procedure can be used to delete entries from these system tables in the MSDB database.

use master
go
sp_configure 'allow', 1
go
reconfigure with override
go
drop proc sp_cleanbackupRestore_log
   go
   create proc sp_cleanbackupRestore_log
   @DeleteBeforeDate datetime
   as
   begin
      Delete from msdb.dbo.sysbackupdetail where backup_id
         in (Select backup_id from msdb.dbo.sysbackuphistory where backup_start <=
   @DeleteBeforeDate)
      Delete from msdb.dbo.sysbackuphistory where backup_start  <=
   @DeleteBeforeDate
      Delete from msdb.dbo.sysrestoredetail where restore_id
         in (Select restore_id from msdb.dbo.sysrestorehistory where backup_start <=
   @DeleteBeforeDate)
      Delete from msdb.dbo.sysrestorehistory where backup_start <=
   @DeleteBeforeDate
   end
go
sp_configure 'allow', 0
go
reconfigure with override
				

You will then need to run the newly created stored procedure. For example, if you wanted to delete all the entries in the tables listed in the stored procedure that occured before January 2, 1997, you would run the following:

exec sp_cleanbackupRestore_log  '1/2/97'
				

If you wish to automate the code, you can use something similar to the following:

declare @DeleteBeforeDate datetime
-- Modify the second parameter as necessary.
-- It is currently set to delete anything older than 60 days.
select  @DeleteBeforeDate = DATEADD(day, -60, getdate())
select  @DeleteBeforeDate

   exec sp_cleanbackupRestore_log  @DeleteBeforeDate
