Enterprise Backups

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

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.

Backups

Simple Disaster Scenario

Backups

Simple Disaster Scenario

A leak in the server room causes the file server to be rendered inoperable.

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?

Backups

Traditional Local Backups to Removable Media

Backups

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

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.

Backups

Remote Backups (Typical Solution)

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.

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.

Review Question How long would it take to download 500

GB of data over a T1? It would take about 30 Days

Enterprise Data Storage

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.

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.

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

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.

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.

Hard Disk Storage Technologies DAS (Direct Attached Storage) NAS (Network Attached Storage) SAN (Storage Area Network)

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.

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.

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.

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.

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.
