Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm running a server with SQL 2008, and backing up the database with a "regular maintenance plan". (I'm not an expert by far in configuring SQL Server).
The execution of this plan is automated by a SQL Server Agent Job.

This seems to work, I have my backup files in the hard drive, and every now and then I download them and restore them in my machine and they seem to work.

However, I tried to run the backup manually today before making some big changes to the schema, and it reported it as failed. However, the backup file did end up in the hard drive, and I was able to restore it in my machine too.

So, I went looking for the history of execution of the Agent job, and sure enough, it's been failing every day. However, I have no idea what is wrong. Again, the backups seem to work, but the fact that it's reporting them as failures every day is a little unsettling for me.

This is the best log I could find of the problem, but I have no idea what to make of it.
Any ideas / pointers on where I should start looking?

Look in the main SQL server logs and the history for the maintenance plan itself to find more info. The job history itself likely won't provide you with the best information.

I couldn't find anything better than that. Could you please tell me where I can find those logs you refer to? Thanks! –  Daniel Magliola Jan 24 '10 at 17:53
    
In SSMS connected to the DB engine, under Management->Maintenance Plans, right click the appropriate plan and hit View History. Also check the SQL server logs under Maintenance->SQL Server Logs, or something to that effect. –  phoebus Jan 24 '10 at 18:53
    
Thank you! There I found it. I was backing up "specific databases", and one of those was one I deleted a while ago. Thanks! –  Daniel Magliola Jan 24 '10 at 19:18
