Just after some general advice from you guys really,

I have a maintenance plan that at current backups up two small databases and then one large database about 30 gig.

after creation I notice that the job was failing so move the time of execution to a period where there is no network traffic which can interfere with the bakcup proccess.

This proved successful for about two months

Hoever now i'm starting to get the same error saying that it's

terminating abnormally

But after it finished upto 100% complete.

I was wondering if its better to seperate this larger database out onto its own plan in order to stop this problem

Any ideas.

30GB is a small database. It should backup in just a few minutes. Please post the exact error message from the SQL Server Error Log that corresponds to the backup failure. The Error Log provides better information.

Hi Tara,

It always comes back with the same error like below.


Execute SQL Task Description: Executing the query "BACKUP DATABASE [CRM_MSCRM] TO DISK = N'\\BACKUP\DB01\CRM_MSCRM_backup_200910280400.bak' WITH NOFORMAT, NOINIT, NAME = N'CRM_MSCRM_backup_20091028040007', SKIP, REWIND, NOUNLOAD, STATS = 10 " failed with the following error: "A nonrecoverable I/O error occurred on file "\\BACKUP... The package execution fa... The step failed.

I find it strange as i've created a secondary job which backups up just the larger database, this runs at the same time as the maintenance jobs however this job never fails.

Would I be better off seperating the database backups out into seperate jobs?

That message doesn't appear to be from the SQL Server Error Log.

I don't ever use maintenance plans. I use custom scripts instead. Here's what I use on all of my systems to backup databases: http://weblogs.sqlteam.com/tarad/archive/2009/09/08/Backup-SQL-Server-2005-and-2008-Databases.aspx
