Disaster Recovery involves real-time file backups, where a file is updated on a clients network, then instantly duplicated into a secure environment. It means that you can regain speedy access and functionality to your core business IT data and infrastructure after a disaster, man-made or other, strikes.
At Nostra, we focus on three key areas of Disaster Recovery.
A disaster recovery (DR) plan is a formal document created by an organisation that contains detailed instructions on how to respond to a disruptive event such as natural disasters, power outages, and cyber-attacks. The plan involves strategies to minimise the effects of a disaster, allowing you to operate or quickly resume key operations.
Disruptions can include power outages, telephone system outages, temporary loss of access to a facility due to a low-impact non-destructive fire, flood or other event. A DR plan should be organised by type of disaster and location. It must contain scripts (instructions) that can be implemented by anyone.
Many attacks can stay undetected for well over 200 days. Within that time, attackers can plant malware that finds its way into the backup sets – infecting even recovery data. Attacks may stay dormant for weeks or months, allowing malware to propagate throughout the system. Even after an attack is detected, it can be extremely difficult to remove malware that is so embedded in an organisation.
Disaster Recovery Testing is the process of ensuring that an organisation can recover data, restore business critical applications and continue operations after a disruption to its IT services.
A disaster recovery test (DR test) checks each step of a disaster recovery plan is outlined in an organisation’s business continuity/disaster recovery (BCDR) planning process.
Communications, data recovery and application recovery are typically a focus of all disaster recovery testing.
Disaster recovery tests should be scheduled and executed on a regular basis throughout the year and be incorporated into all planned maintenance and staff training.
Audit logs and other data should be analysed to determine what worked / didn’t work as expected, and what changes need to be made in the DR plan.
A Business Impact Analysis (BIA) is a systematic process to determine and evaluate the potential effects of an interruption to critical business operations as a result of a disaster, accident or emergency.
Following the BIA, this subsequent report describes the potential risks specific to the particular organisation studied.
A BIA is likely to identify costs linked to failures, such as loss of cash flow, replacement of equipment, salaries paid to catch up with a backlog of work, loss of profits, staff and data, and so on. A BIA report quantifies the importance of business components and may suggest appropriate fund allocation for measures to protect them.
A BIA should assess a disaster’s impact over time and help to establish recovery strategies, priorities, and requirements for resources and time.
