Definition: Recovery Lifecycle

Source: IT Service Continuity Management

21

Definition: Recovery Time Objective (RTO)

The maximum time allowed for your environment to be restored after an outage or data loss

Example: 2 hour RTO means that data or farm must be restore within 2 hours of the system outage.

22

Definition: Recovery Point Objective (RPO)

Defined: the maximum tolerable time period in which data might be lost due to a server farm failure

Example: 4 hour RPO means that SharePoint must be backed at least every 4 hours

Definition: High Availability

A systematic approach / plan– Ensures that a data system, specifically, SharePoint and its content is continuously

operational and “live.”

Usually applied to the most critical content – Can never be down or “unavailable” and – Needs a safety net in the event of an outage

• Both planned or unplanned

Readable Copies

AlwaysOn Availability Groups - Synchronous (Dual-phase commit, no data loss, can’t operate across WAN)

None 5-7 Seconds Yes 0 - 2

AlwaysOn Availability Groups - Asynchronous (Latency tolerant, cross WAN option, potential for data loss)

Seconds Minutes No 0 - 4

AlwaysOn Failover Cluster Instance (FCI) - Traditional shared storage clustering

NA 30 Seconds to several minutes (depending on disk failover)

Analyst Perspective – Content Replication

Allows for SharePoint information to extend beyond a single geographic location

Information can be located logically closer to the end user

Creates a highly resilient, distributed environment that is easier to scale

Supports the needs of compliance, backup and archiving of SharePoint Information

Can reduce overall operational overhead

Replication In Action

You have 2 SharePoint farms that have been synchronized.

31

Replication In Action

Nothing is constant and outages do occur, whether planned or unplanned.

32

Replication In Action

Simply redirect your end users to your other farm.

33

Replication In Action

Then redirect your end users back to the original farm.

35

Key Considerations for Content Replication

Cost of a disruption

Amount of content that needs to be highly available

Collaboration/Mission Critical requirements – Always up-to-date content through active synchronization

Number of farms being connected, and their geographic distribution

Bandwidth required for replication

Conflict resolutions, fault-tolerance and fail-over

Migration/Upgrade path of SharePoint and third party tool

Preferred access to control

36

What to do next

Prioritize Content− Mission Criticality− Compliance/ Regulatory needs

Identify the initial effort to manage content− Database growth and user loads− Measure operational tasks required in current state− Identify bandwidth usage and latency

Perform the Business Cost Analysis− Describe the risk of NOT utilizing Replication− How will the Infrastructure be managed?
