This is a story about NEd ~ Jr DBA

Ed got successful backup notifications

Ed thought VERIFY meant his backup would be good when it was successful

Ed never heard of DBCC CHECKDB

Ed never ran DBCC CHECKDB on his databases nor did he restore them!

Backup Strategies Are For Losers…

of DATA!Recovery

Strategies are for Winners!

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?

So what is a recovery strategy?

Final Review

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.

Best Practices for Backups

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.
