4. Business continuity planning (BCP)
Let’s start to connect all dots 1 4

5. “
The process of creating systems of
prevention and recovery in the event of a
disaster. In addition to prevention, the goal
is to enable ongoing operation, before and
during the execution of disaster recovery.

6. 6
Disaster recovery (DR)
An area of BCP that aims to protect an organization from the effects of
significant natural or human-induced disaster. DR allows an organization to
maintain or quickly resume mission-critical functions following such an event.
High availability (HA)
A characteristic of a system, which aims to ensure an agreed level of
operational performance, usually uptime, for a long period of time.
DR and HA concept

7. 7
Recovery Time Objective (RTO)
The maximum tolerable length of time that a computer, system, network, or
application can be down after a failure or disaster occurs.
Recovery Point Objective (RPO)
The amount of data at risk. It’s determined by the amount of time between data
protection events and reflects the amount of data that is lost during a disaster
recovery.

RTO and RPO with Sitecore MC

12. Basic DR
In the event of an outage in the primary
data center, a new Sitecore production
environment is created in a secondary
data center. During the creation of the
secondary environment, a simple outage
page is shown to customers to make
them aware that the site is temporarily
down. Because a new environment must
be created in a secondary data center,
this recovery option has the longer RTO
but is the less expensive option.
12

13. Basic DR (Steps)
• Scheduled back up every 3 hours of the assets below into the secondary data center based on the
designated RPO: Back up the databases
• Back up the WebApps
• Back up the connection strings (for the credentials)
• Back up the sizes/tiers of the resources
• Setup of outage page to be shown to the customers while there is a disaster
• Setup of Traffic Manager to switch between primary CD and outage page
• Setup of email alerts to notify Managed Cloud operations team when the availability tests fail
13

14. Managed DR
For the Managed DR service, the
secondary data center always has a
complete Sitecore environment setup with
all Azure Resources matching the
sizes/instances count in the primary data
center. This recovery option has a shorter
RTO as the failover is automatic.
14

15. Unsupported Scenarios
There are a small set of scenarios where it might not be possible to restore a production site
into the secondary data center. Some examples of some of these are (not exhaustive):
A global Azure service such as authentication or Traffic Manager is down
Both the primary and the “backup” (secondary) data centers are down at the same time
Large scale global network failure/outage
Network connection between primary and secondary data centers is down
