The Most Crucial Element of Disaster Recovery
Backup plans spell out exactly what should be backed up, how often, where backups should be stored and for how long. Often overlooked, however, is a detailed recovery plan, the most crucial element of disaster and recovery planning.
Based on a risk assessment for critical functions that prioritizes the risk posed by cyberattacks, human error, software bugs, natural disasters and the like, the recovery plan should be developed long before disaster strikes.
Such plans should spell out the policies and procedures that must be taken before, during and after a disaster, and must specify recovery point objectives (how much data loss is acceptable) and recovery time objectives (how quickly systems can be up and running).
A critical step in recovery planning is checking the backups. Many organizations check backup quality and integrity early on, but then may go months without verifying that subsequent backup jobs — which run to completion — have backed up anything successfully.
