6. Beware of the Blogs
 There is some amazing
advice out there. But…
 Anybody can put bad
advice on the internet
 Trust people you know
 Assume I’m an idiot
 I don’t trust people who
say “ALWAYS” or
“NEVER”
 Test everything in your
own test environment
first.

7. Lets talk strategy
 Who has a backup strategy?
 Do you have a recovery strategy?

8. If you have a backup strategy and not a
recovery strategy, you're doing it wrong!

9. Lets talk business
 SLA: Service Level Agreements (with your
customers)
 OLA: Operational Level Agreements (with your
organization)
 RTO: how quickly you need to be recovered
(usually in hours) after a failure
 RPO: how much data loss (usually in minutes) is
acceptable

10. The lower your RTO and RPO, the greater
the cost.

11. Myth Busting
 Backup and Recovery are NOT the same
thing as high availability.
 High Availability (Clustering, Always On) are
a completely different topic.
 Log Shipping is another topic for another day.

12. Recovery Models
 Simple Recovery – Allows us to restore a full
backup.
 Full Recovery
 Allows us to restore a full backup
 Then roll forward transaction log backups
 Stop at a specific point in time
 BULK LOGGED – Similar to Full Recovery,
but we’re not talking about it today.

13. What is the right Recovery Model to Use?
 It depends on your RPO
 It also depends on your data and business
processes

14. Why RPO Matters
 Does your RPO allow you to lose the data
between full backups?
 Probably not.
 But it can happen.

15. Why Your Data and Business Matters
 How many of your databases have data that
doesn’t change between full backups?
 Can your data be recreated from import files
or re-running a process to run data updates?

16. Matching Recovery Models to Backups
 SIMPLE: Regular FULL backups
 FULL:
 Regular FULL backups
 AND frequent transaction log backups
 How frequent? It depends on your RPO.

17. A Word on Log Shipping
 Another form of Backup and Recovery
 Three Step Process
 Backup Transaction Logs
 Copies Transaction Log Backups to Target
 Restores Transaction Log Backups on Target
 Very helpful for Disaster Recovery

18. Had enough theory?

19. Let’s Demo

20. If you have a backup strategy and not a
recovery strategy, you're doing it wrong!
