Disaster Recovery Terminology
Business Continuity ensures an
organization's critical business
functions continue to operate or
recover quickly despite serious
incidents.
Disaster Recovery (DR) enables the
recovery or continuation of vital
technology infrastructure and
systems following a natural or
human-induced disaster.
RPO is the maximum targeted period
in which data might be lost from an
IT service due to a major incident.
How quickly you need this asset to be
recovered?e.g. 1min? 15min? 1hr?
RTO is a targeted duration of which a
business process must be restored
after a disaster or disruption. How
‘fresh’ the recovery must be for the asset?
e.g. zero data loss, 15mins out of date?

Traditional Approach to DR
Focus is on protecting data
– Tape backup
– Imaging
Poor performance
– Slow RTO, RPO (days)
Hidden costs
– How do we get the data back
in to a useable state?
– How long to rebuild server?
Focus is on protecting app
– Clustering
– Like-for-like infrastructure
Performance@ what price?
– Near-zero RTO, RPO
High cost
– Duplicate infrastructure
– Management complexity
Backup Double Infrastructure

Why Disaster Recovery ?
Every company understands the
importance of having a disaster recovery
plan in place.
What keeps most companies from
implementing a DR plan?

Disaster Recovery With AWS
High Availability Backup Disaster Recovery
Make sure your data is
safe
Keep your applications
running 24x7
Get your applications and
data back after a major
disaster

AWS compared to traditional disaster recovery
High cost to build
disaster recovery Sites

(CAPEX)
High cost of storage,
backup, archival and
retrieval tools, and
processes (OPEX)
Difficult planning,
procurement and
deployment
Challenging to verify
DR plans
Single level of DR

Advantages
• Simple to get started
• Cost effective (mostly backup storage)
Preparation Phase
• Start SoftNAS Cloud 30 day free trial
• Install and configure SoftNAS Cloud
• Describe procedure to restore from backup
onAWS
• Know whichAMI to use, build your
own as needed
• Know how to switch to new system
• Know how to configure the
deployment
In Case of Disaster
• Retrieve backups from S3
• Bring up required infrastructure
• EC2 instances with prepared AMIs,
Load Balancing, etc.
• Restore system from backup
• Switch over to the new system
• Adjust DNS records to point to AWS
Objectives
• RTO: as long as it takes to bring up
infrastructure and restore system from
backups
• RPO: time since last backup
Backup & Restore – How it Works
19. Build,SkillandEnable
Advantages
• Very cost effective (fewer 24/7 resources)
Preparation Phase
• Enable replication of all critical data to
AWS
• Prepare all required resources for
automatic start
• AMIs, Network Settings, Load
Balancing, etc.
• Reserved Instances
In Case of Disaster
• Automatically bring up resources around
the replicated core data set
• Scale the system as needed to handle
current production traffic
• Switch over to the new system
• Adjust DNS records to point to AWS
Objectives
• RTO: around 4hours
• RPO: around 12 hours

23. Build,SkillandEnable
Advantages
• At any moment can take all production
load
Preparation
• Fully scaling in/out with production load
In Case of Disaster
• Immediately fail over all production load
• Adjust DNS records to point to AWS
Objectives
• RTO: minutes
• RPO: minutes

Portal for vCenter to import your VM
• Windows and Linux VMs that use VMware
ESX or Workstation, Microsoft Hyper-V, and
Citrix Xen virtualization
Active Directory
AWS Directory Service
• AD Connector
• connect your Microsoft Active Directory to the AWS
Cloud
• Integrate with your existing RADIUS-based MFA
infrastructure
• Domain Join Instances
Windows - Database
Amazon RDS for SQL Server
• Import Your Data – pre-steps
• Create a snapshot of the target database.
• Disable automated backups on the target database.
• Disable foreign key constraints, if applicable.
• Drop indexes, if applicable.
• Disable database triggers, if applicable.
