4. Enterprise Backups

5. Backups What do we mean by Backups?  Making copies of data so that these additional copies may be used to restore the original after a data loss event.  Deleted or copied over a file  Major disaster

6. Backups Backups are not the same as Disaster Recovery.  Disaster Recovery (DR) is the process, policies and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster.  Backups are part of DR but backups alone are not a DR plan.

7. Backups Simple Disaster Scenario

8. Backups Simple Disaster Scenario A leak in the server room causes the file server to be rendered inoperable.

9. Backups Simple Disaster Scenario  Backups exist but…  Where do we restore them to?  Who’s going to do the restoration?  How do we communicate the outage with those affected? (Employees, customers, other agencies)  How do we function in the mean time?

10. Backups Traditional Local Backups to Removable Media

11. Backups Traditional Local Backups - Advantages  Relatively inexpensive  Quick and Easy to set up  Media is portable

12. Backups Traditional Backups - Disadvantages  Many types of backup media wear out over time and can fail.  Backup media stored onsite may be destroyed if a facility is lost or damaged.  Moving backup media offsite can be inconvenient and insecure.  Hardware and software to read the media must be available as well as a target to restore the data to.

13. Backups Remote Backups (Typical Solution)

14. Backups Remote Backups - Advantages  Data is encrypted and stored securely offsite.  Compliant with Sarbanes-Oxley, HIPAA and GRAM- Leach-Bliley  Data is protected from facility loss.  Data can be restored to any physical location that has Internet connectivity.

15. Backups Remote Backups - Disadvantages  Restoration can take a long time due to bandwidth limitations.  Example: download 500GB over a T1 connection would take about 30 days.  A destination server is required.

20. Backups Worksighted LiveBackup  Multiple recovery points  Backups are infinitely customizable  Standard 9 generations  Archive  Local storage  Scales with customer and data

21. Review Question  How long would it take to download 500 GB of data over a T1?  It would take about 30 Days

22. Enterprise Data Storage

23. Storage 101 What do we mean by “Storage?”  Computer components and recording media that retain digital data used for computing for some interval of time.  That means Storage is where your Programs, Email, Word Docs, Excel Docs, PDFs, Calendars, Contacts, QuickBooks Data, CAD Drawings, Databases, Pictures, Videos, Music, Websites, Facebook Statuses, Tweets, Backups, Tax Information, Games, Maps, Instant Messages, Your Child’s Grades, Shopping Lists, etc. all live.

24. Storage 101 And the data continues to grow….  2009 – Estimated total digital data = 800,000 petabytes. PB = 1 million GB. That’s a stack of DVDs reaching from the Earth to the Moon and back.  2010 – it will grow to about 1.2 million petabytes  2020 – 35 million petabytes or 44x the data in 2009 The stack of DVDs would now reach halfway to Mars.

25. Storage 101 Common Types of Storage  Magnetic – Floppy Disks, Hard Disks and Magnetic Tape  Optical – CDs and DVDs  Semiconductor – Flash Drives, SD Cards, Memory Sticks, Solid State Hard Disks

26. Storage 101 Protecting data on hard drives  RAID – Redundant Array of Independent Disks  A method for combining multiple hard disk drives for the purposes of increasing storage, performance or fault tolerance.  The RAID “Level” indicates the way the data is organized on the disks and the level of redundancy.

27. Storage 101 RAID 5 - 3 hard drives in server but usable disk space of 2 hard drives. = You can lose one drive and still function. 3x 73GB hard drives 146GB Usable

29. Storage 101 Hard Disk Storage Technologies  DAS (Direct Attached Storage)  NAS (Network Attached Storage)  SAN (Storage Area Network)

30. Storage 101 Direct Attached Storage (DAS)  Hard drives in a PC or Server  Disks are directly connected to the machine often residing in the chassis with the rest of the server components.  Simple to deploy and has a low initial cost.  Ideal for environments with a single server or a few servers.  Also good as a stepping stone to networked storage.

31. Storage 101 Direct Attached Storage (DAS)  As things grow management complexity can grow quickly.  Adding storage to a server or moving excess storage from one server to another can be difficult or impractical.

32. Storage 101 Network Attached Storage (NAS)  A Special purpose device comprised of hard disks and management software that is dedicated to serving files over a network.  Not used as often because of limited applications as opposed to SAN.

33. Storage 101 Storage Area Network (SAN)  A dedicated high performance storage network that transfers data between servers and storage devices.  Uses either Fiber Channel or iSCSI.  Optimized for moving large chunks of data.  Typically designed with scalability and fault tolerance in mind.

34. Storage 101 Storage Area Network (SAN)  Allows for flexible and efficient provisioning and organizing of storage.  A SAN volume is presented as local storage to the server’s OS meaning that it can be used in most any storage application.  Higher initial cost and more complicated to manage than DAS or NAS.

36. Review Question  What does SAN stand for?  Storage Area Network
