IT Resiliency is the ability to provide and maintain an acceptable level of service in the face of faults and challenges to normal operation Pressures/dependencies;

More reliance on IT to deliver Services
Uptime 24/7
More complex IT Infrastructure

Improvements

1. Business continuity and Disaster recovery requirements considered for any

new IT system, application or service [in place]

2. Undertake a Business Impact Analysis with Health and Safety Officer [in

place]

3. Improve the resilience of Power – onsite generator to be considered
4. Identify options and implement mirroring offsite storage of data and critical

servers [in progress]

– Upgrade existing backup solution [completed] – Undertake system health check [end of March] – Agreement for off storage site [end of May]

5. After above, test the restore of the offsite data
