As a production Database Administrator, I do not want to give Developers direct access to the SQL Server Agent job log especially for servers in the DMZ. Another problem we have is that when there is a lot of log data for a job, the default job log doesn't contain the full log detail and that makes it harder to troubleshoot. Most of all, we are trying not to use a different code set for deployment based on the environment. Basically we want to use the same methods to deploy our jobs to Development, Test and Production.

The most critical task for all DBAs is to have a Backup and Recovery strategy that ensures, every day, that in the event of a disaster they can restore and recover any database, within acceptable limits for data loss and downtime. Even with all the required backups in place, it's easy to miss subtle failings in the overall plan that can, and eventually will, defeat your recovery plans.

In February 2008, Microsoft announced a record-breaking data load using Microsoft® SQL Server® Integration Services (SSIS): 1 TB of data in less than 30 minutes. That data load, using SQL Server Integration Services, was 30% faster than the previous best time using a commercial ETL tool. This paper outlines what it took: the software, hardware, and configuration used. We will describe what we did to achieve that result, and offer suggestions for how to relate these techniques to typical scenarios. Even for customers who don't have needs quite like this benchmark, such efforts can teach a lot about getting optimal performance.

While doing some testing of an application, I wanted to reset my environment after doing some testing with this code:
USE DNRTest BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak' GO /* Bunch of stuff tested here */RESTORE DATABASE DNRTest FROM DISK = 'dnrtest.bak' WITH REPLACEWhat happens if this runs, assuming the "bunch of stuff" isn't anything affecting the instance. See possible answers
