The Importance of a Disaster Recovery Plan
09 December, 2015
A disaster is any event which causes unnecessary downtime for a data centre. Mother Nature can be blamed for many of these events, which makes them even more unpredictable. For example, if Google can fall victim to a natural disaster, then anyone can. Therefore, a solid and comprehensive disaster recovery plan is absolutely crucial to protect the business in the event of a natural disaster or any other emergency.
All companies should have a disaster recovery plan, in order so they can continue operating if the office or headquarters is damaged and unsuitable for business. However, it’s even more essential for businesses to have an up to date recovery plan for data centres, as many businesses now rely so heavily on them. Businesses need to be prepared for anything – here’s some tips to think about when designing disaster recovery strategies and plans.
Critical system threats
Identify the various critical systems which are vital for business operations. This can include physical equipment and security procedures in addition to servers and infrastructure. Identify the threat of a disaster – what would happen to each component? Servers could fail, data could be lost, equipment or buildings destroyed. Write down exactly how this would affect the running of the business – then you can start planning a prevention and response strategy.
You may need to consider securing an alternative location, away from the current data centre site, to get things back up and running as soon as possible following a disaster. If the risk of the building being destroyed or needing urgent construction work after a natural disaster is high, then having a back-up site is essential. You’ll also need a full relocation plan for staff and equipment – or ideally have backup equipment ready to resume operations.
Focus on data
One of the biggest worries of IT managers is that data can be wiped and lost forever if a data centre is hit by floods, an earthquake or struck by lightning. The most important thing here is a prevention strategy – having back-up generators and disks at all times. However once disaster strikes, time is of the essence and a strategy should be ensured so the IT team can recover as much as possible, as soon as possible.
If you have neglected your DR plan then it’s time to revisit it – a prepared business can enjoy business continuity, regardless of what happens to it.
