Agenda

Briefly, what is Disaster Recovery?

vs. Archiving and Backup

Disaster Recovery

Archiving Backup Disaster Recovery

moving data that is no longer ac:vely used to a separate data storage device for long-‐

term reten:on

making copies of data which may be used to restore the original aHer loss, dele:on,

or corrup:on

the process, policies and procedures related to

preparing for recovery or con:nua:on of technology infrastructure aHer a natural or human-‐induced disaster

a hot topic for businesses worldwide

Examples of Disasters

Flooding and cyclone in Australia Mudslides Rio de Janeiro

Earthquake in New Zealand Tsunami and flooding in Japan Tornados and flooding in USA

Flooding in Taiwan

…and of course, human error…

DR is part of a wider set of policies and controls: Business Con=nuity

What is Disaster Recovery?

Recovery Time Objec:ve (RTO)

How quickly you need this assets to be

recovered? e.g. 1min? 15min? 1hr? 4hrs? 1day?

Recovery Point Objec:ve (RPO)

How ‘fresh’ the recovery must be for the

asset? e.g. zero data loss, 15mins out of date?

Why AWS for Disaster Recovery?

Common DR Architectures

4 main paaerns

Common DR architectures

Backup & Restore Pilot light

Warm standby in AWS

Mul=-‐site solu=on in AWS & on-‐

premise

We’ll focus on 3 of them…



Warm standby in AWS


premise

Let’s start with Backup & Restore



Warm standby in AWS


premise

Advantages to star=ng a journey with this paaern

Backup & Restore paiern

Simple to get started

Easy star=ng point for exploring the AWS cloud

Low technical barrier to entry

Focus on incorpora=ng cloud into your DR strategy, not on complex technical issues related to hot-‐hot systems

Cost effec:ve

Very high levels of data durability at low price

Cost of storing snapshots in S3

Archiving possibili=es beyond tape using Glacier

The prepara=on process…


Take backups of current systems

Store backups in S3

Move to long term archive in Glacier

The process…


Take backups of current systems

Store backups in S3

Detail how you will restoring from backup or recover from archive

Move to long term archive in Glacier

Push backups to AWS

Store AMIs for servers

Let’s look at the Pilot Light paaern…



Warm standby in AWS


premise

Moving along the DR spectrum…

Pilot light architecture

Build resources around replicated dataset

Keep ‘pilot light’ on by replica=ng core

databases

Build AWS resources around dataset and leave in stopped state





databases


Scale resources in AWS in response to a DR event

Start up pool of resources in AWS when

events dictate

Ramp up to produc=on capacity by star=ng and scaling resources

Switch-‐over to system in AWS

Pilot light – prepara:on phase

Customer example

Haven Power is taking advantage of the lower costs and increased flexibility of cloud computing

EU region DR site for range of business applica:ons

All running in a Virtual Private Cloud (VPC)

DR provision for applica:ons dependent on Oracle and SQL Server databases

Includes DR for Ac:ve Directory and Windows file shares
