Scope the failure
Decide whether the issue is data loss, service loss, boot failure, or misconfiguration.
Backup, Restore, and Recovery Decision Flow
Understand when to inspect, restore, repair, or roll back instead of jumping straight to the biggest recovery action.

Backup, Restore, and Recovery Decision Flow
Recovery work becomes dangerous when people skip evidence collection and jump straight to restore or rollback. This visual keeps recovery decisions disciplined.
Diagram 1 2 3 4 5
Collect evidence
Logs, timestamps, and affected systems define the real recovery need.
Choose intervention size
Repair, rollback, restore, or rebuild based on impact and confidence.
Execute safely
Apply the chosen recovery action with rollback awareness and the right source data.
Verify the outcome
Confirm the real workload and data are healthy after recovery.
What to notice
- Recovery starts with scope and evidence, not with the restore button.
- Repair, rollback, restore, and rebuild are different levels of intervention.
- Verification after recovery is as important as the recovery step itself.
Common confusion
- Using full restore when a smaller repair would work.
- Starting recovery before confirming what data or service is actually affected.
- Stopping after the system boots without verifying the real workload.
