DISASTER RECOVERY GLOSSARY

Presented by

ALERT

An emergency notification generated when a potentially disruptive event occurs. Depending on your DR setup, alerts may be sent when precursor conditions are met or immediately after a service disruption. Alerts typically include instructions on how to proceed, such as “act” or “stand by.”

BACKUP

The process of copying and storing data at an alternate location for use in the event of disaster. Can be accomplished using local servers, cloud-based migration, or physical media such as magnetic tape.

CONTINUOUS AVAILABILITY

Refers to the ability of specific systems of processes to continue operations without any noticeable interruption even during a disaster. Typically requires multisite redundancy and uninterrupted Internet connectivity.

DISASTER RECOVERY

The entire process of identifying, responding to and mitigating issues, and remediating all systems after a disaster has occurred. Includes recovery of data, equipment, applications and other processes to a predefined standard.

EXERCISE

Regular testing of a DR plan to ensure reliability and speed. Ideally, companies should perform multiple exercises each year, simulating specific disaster scenarios.

A preset time limit that identifies the goal for maximum downtime allowed after a disaster. RTOs are met when all systems are back up and running within that timeframe. Regular testing is critical to meet RTOs.RECOVERY TIME

OBJECTIVE (RTO)

The amount of data which must be recovered in an “acceptable loss” scenario. This helps determine the type and frequency of backups required.RECOVERY POINT

OBJECTIVE (RPO)

The setup of computing services in which both the user and cloud services vendor are accountable for portions of IT security.SHARED

RESPONSIBILITY MODEL

An evaluation of current IT infrastructure and potential disaster events to determine DR priorities and create disaster recovery plans. Many companies now rely on third-party auditors to ensure a thorough risk assessment.RISK ASSESSMENT

The use of multiple sources, storage methods and connections to ensure that even during a disaster you still have access to key data and processes.

REDUNDANCY

The ability to keep business operations going even after disaster occurs. Beyond simply “recovering” from a disaster, BC solutions focus on minimal disruption of day-to-day processes.

BUSINESS CONTINUITY

Refers specifically to the restoration of mission-critical applications and software. Occurs after the disaster has ended and basic recovery of platforms and operating systems has taken place.

APPLICATION RECOVERY

Refers to the ability of a system or network to keep working with minimal downtime. For example, many cloud providers now offer 99.999 percent uptime. Translated, that means there are just over 5 minutes of downtime per year.

HIGH AVAILABILITY

Nonlocal storage and computing facilities that provide your company full access to a replica of your current IT environment. Accessed through secure Internet connections anywhere, anytime.REMOTE

ASSET

Anything your company deems important and necessary to recover. Typically, assets are data in some form — for example, credit card information or consumers’ personal data. Assets also can include intellectual property, finances or operating equipment.

A secondary workspace that contains all of the necessary technology (including hardware, such as PCs, phones and network connections) to keep your business running if your primary office space is disrupted.
