Backup - Verify backup and Do database consistency check

Verifying backup can ensure the backup set is readable , but the program does not attempt to verify the structure of the data contained in the backup volumes .

Doing database consistency check can checks the allocation and structural integrity of all the objects in the specified database . If errors occur , it indicate potential problems in the database and should be corrected immediately . Program only report error result , if you want to get more detail information , you have to run the DBCC command in Query Analyzer or Management Studio . The command format is : 

DBCC CHECKDB ('your database name')

For more detail information about this command , please see the SQL Server documentations.




Verify backup set after job : If you select this option , program will check to see that backup set created by the job is complete and that all volumes are readable. However, program does not attempt to verify the structure of the data contained in the backup volumes. So the recommendation is :
     You should periodically test your full, differential and transaction log backups on a standby server or a development server. You don't need to test every single backup that you create, but you should go through the testing process for a full recovery just so you know the steps and how the process works. If your backup files are intact and the restore is successful, you are pretty much guaranteed that your backup files will be good in the future. However, things may change on your network or server that are out of your control, so it is a good idea to run your tests on a set schedule (i.e., once a month) to ensure nothing has changed that may negatively impact your restore process.

Database consistency check :  DBCC checks the allocation and structural integrity of the database to be backed up.
