  1. 1. VMware Backup Integrity<br />Eric Siebert<br />vExpert, Author, Blogger<br />Blog: http://vsphere-land.com<br />http://searchvmware.com<br />Twitter: @ericsiebert<br />
  2. 2. About the speaker<br />25 year IT industry veteran.<br />vSphere Land blog: http://vmware-land.com/<br />Author of popular books<br />Contributor to industry publications<br />vExpert nomination<br />
  3. 3. Agenda<br />Why backup integrity is critical<br />Traditional backup verification methods<br />How virtualization makes verification easier<br />Quiescing is critical to consistency<br />VMware Tools is important<br />
  4. 4. Why backup integrity is critical?<br /><ul><li>Good backups are important, good restores is more important
  5. 5. Backups worthless without proper restore capabilities
  6. 6. No errors reported doesn’t imply recoverability
  7. 7. Test and verify backups are working and recoverable</li></ul>Good backup<br />APP<br />Backup<br />Restore<br />Good Restore?<br />
  8. 8. The challenge of verifying backups<br /><ul><li>Reporting a successful backup is not a complete verification
  9. 9. File, application, database and server restores needed
  10. 10. Proper verification can be time-consuming
  11. 11. Restoring files is easy, applications or whole VM is complicated</li></ul>Need to ensure that VM backups are usable<br />Good backup<br />Non-production environment<br />APP<br />APP<br />
  12. 12. Traditional backup verification methods<br /><ul><li>Verification can’t impact production VMs
  13. 13. Requires un-used hardware to test restore
  14. 14. Bare-metal restores for verification is impractical
  15. 15. Difficult with many server models and generations</li></ul>Ensuring recoverability with legacy tools unfeasible<br />Non-production environment<br />Same App<br />Backup<br />Same Drivers<br />Restore<br />Same OS<br />
  16. 16. Data Restore Levels<br />3 Different levels to backup and restore<br />Image level<br />File level<br />Application item level<br />Backup<br />SQL<br />record<br />Restore<br />
  17. 17. How virtualization makes verification easier<br /><ul><li>VMseasily restored to host and powered on
  18. 18. Network isolation prevents impacting production systems
  19. 19. Multiple VMs restored to tests applications
  20. 20. No extra hardware required </li></ul>The process is easier with virtualization<br />Backup<br />Restore<br />
  21. 21. Consistency is the key to good backups<br /><ul><li>OS, applications and data need to be in proper state
  22. 22. Critical for transactional applications: AD, SQL and Exchange</li></ul>Transaction-based applications<br />Exchange SQL Active Directory More<br /><ul><li>Server must be prepared before snapshot
  23. 23. Pending transactions must completed
  24. 24. Missing data can cause corruption</li></ul>Backup<br />Restore<br />
