15 How do we backup this data? How do we restore logins, jobs, linked servers, system configuration settings, etc. Are you backing up the resource database? How are we going to recover this data in the event of a failure? How much data can we afford to lose in the event of a failure? How quickly does this data need to be restored and operational?

25 1. Make sure you are not storing your backups in the same physical location as the database files. When your physical drive goes bad, you should be able to use the other drive or remote location that stored the backups in order to perform a restore. Keep in mind that you could create several logical volumes or partitions from a same physical disk drive. Carefully study the disk partition and logical column layouts before choosing a storage location for the backups. 2. Make sure you have a proper backup schedule established according to the needs of the application and business requirements. As the backups get old, the risk of data loss is higher unless you have a way to regenerate all the data till the point of failure. Backup Strategies are for Losers! 8/9/

26 3. Use the verification options provided by the backup utilities [BACKUP TSQL command, SQL Server Maintenance Plans, your backup software or solution, etc]. 4. Use advanced features like BACKUP CHECKSUM to detect problems with the backup media itself. 5. Make sure to actually restore the backups on a test server and verify that you can restore with all the options and conditions you need to use during a planned or un-planned downtime.
