Industry Terms You Should Know: Disaster Recovery

Welcome to our new blog series, “Industry Terms You Should Know.” This week, we kick off our series by introducing all the key facts and terms you should know when it comes to disaster recovery and business continuity planning. Read on to learn more.

Disaster Recovery (DR)disaster recovery

DR replicates data and technology functions in real time to an offsite location.

Your IT provider’s DR platforms should provide a real-time replica of production technology in a secure, off-site data center.

DR enables firms to restore operations to an offsite location immediately, preventing interruptions to the workday if the event renders the primary worksite unusable.

DR creates a full image of disk drives and servers, and can restore and install virtual servers quickly (often within minutes to hours depending on the specific systems and plan in place).

A DR system should be in place for the most critical business operations.

Hot Site, Cold Site, and Warm Site

DR sites can include hot sites, which are locations that businesses can fully restore their operations to immediately if their current place of work is not functioning ; warm sites, which allow some operations to be restored immediately; and cold sites, which do not allow any operations to be restored immediately.

Recovery Time Objective (RTO) and Recovery Point Objective (RPO)

Recovery Point Objective, RPO for short, is part of business continuity planning and refers to the maximum amount of time in which data might be lost due to an incident.

Recovery Time Objective, RTO for short, is the required amount time and service level that business functions must be restored to in order to avoid the consequences associated with breaking the continuity of operations.

Business Continuity Planning (BCP)

BCP details where to work and how to execute mission-critical tasks in the case of an emergency or event.

Emergency notification systems, detailed continuity plans, and employee awareness seminars all comprise business continuity and ensure that staff is prepared in the case of an unexpected event.

Business continuity plans are put into place after a thorough analysis of an organization’s business functions.

Data Backup

Data backup copies and archives files and folders in the case that data is lost due to an event ranging from technology failure to poor weather.

Your IT provider’s data backup solutions should store files off site, and archive data on a scheduled basis to provide a static copy of essential files.

Data backup is a component of a DR strategy.

Backed up data is not always available immediately.

It can take days to weeks to piece the data back together and reinstall it on new servers.
