Disaster Recovery
System failure, a cyber incident or disruption at a site can affect applications, data and the people who rely on them. CTSL helps organisations assess critical systems and define recovery priorities, then develop a recovery strategy around those requirements. Planning includes technical dependencies, responsibilities and communications, not just where a backup is stored. Recovery performance depends on the agreed design and testing.
Service areas
Critical-system assessment
Identify important systems and data, their dependencies and the operational priorities that should guide the recovery plan.
Recovery objectives and strategy
Define RTO and RPO requirements and shape a tailored strategy for the systems and disruption scenarios being considered.
Backup and data replication
Review backup and replication requirements in relation to recovery priorities, data locations and the proposed design.
Off-site, cloud and failover design
Consider off-site or cloud recovery and failover arrangements where these fit the agreed systems and operational requirements.
Roles and communications
Define recovery responsibilities and communication arrangements so technical activity and organisational decisions are coordinated.
Testing and revision
Schedule recovery testing, validation and reporting, and use the findings to review and revise the agreed strategy.
How we can help
Critical operations
Which activities must be restored first, and which systems, data and people do they depend on?
Recovery expectations
What recovery time objective (RTO) and recovery point objective (RPO) does each important system require?
Existing backup arrangements
What is backed up or replicated today, where is it held, and what recovery testing has been performed?
Disruption and coordination
How would a system failure, cyber incident or site disruption affect access, decision-making and communication?
Planning your project
01
Establish priorities
Discuss critical operations, dependencies and acceptable recovery objectives with the relevant decision-makers.
02
Agree the recovery design
Select the strategy, backup or replication arrangements, roles and communication requirements.
03
Plan validation and review
Agree testing, reporting and revision arrangements rather than assuming recovery performance without validation.
