- Level
- L3 — Infrastructure engineer
- Duration

Learning objectives
- 01Produce consistent state snapshots
- 02Restore a node from a snapshot and measure recovery time
- 03Distinguish chain-data backup from key backup
Guided lab
Destroy a node's data and restore it from a snapshot, stopwatch running.
Independent lab
Automate snapshots and integrity checks, then demonstrate an automated restore.
Security angle
A snapshot can contain keys: encryption at rest and access control are mandatory.
Assessment
Successful restore with measured recovery time, verified by a peer.
