Preparing for serious loss.
WHAT DISASTER RECOVERY ADDRESSES
Loss of a site, a system, or data, beyond what redundancy handles.
WHAT TO DEFINE
How long you can be without the service How much data you can afford to lose
WHAT THOSE TWO FIGURES DRIVE
Every technical decision and every cost.
WHAT STRATEGIES EXIST, BY COST
Backups restored to new infrastructure when needed A minimal standby environment, scaled up on failure A partially running environment A fully running second site
WHAT EACH COSTS
Progressively more, in money and in operational effort.
WHAT TO CHOOSE
The cheapest meeting the defined figures.
WHAT TO DOCUMENT
The procedure, step by step Who decides to invoke it Contact details Dependencies and their order
WHERE TO KEEP IT
Somewhere reachable when your systems are unavailable.
WHY
A plan stored only inside the failed system is useless.
WHAT TO TEST
The whole procedure, periodically.
WHAT TESTING REVEALS
Missing credentials, undocumented steps, and dependencies nobody recorded.
WHAT TO MEASURE
How long recovery actually takes.
