Restore Test
Prove you can restore — test recovery on $LAB backup, not production without scope.
Visual · t16_restore_test
Untested backup = wish. Original Cyberlium.
A backup that never restores is a screensaver for anxiety.
Restore test: pick file or VM snapshot from YOUR backup, restore to isolated $LAB path, verify hash or content, document time-to-restore. Schedule quarterly for lab. Defenders measure RTO/RPO at literacy level — never 'test restore' by overwriting production or classmate VMs. Failed restore in lab is a valuable finding on YOUR process.
1. Restore steps
Select backup → isolate restore target → restore → verify → note duration.
Do not restore malware samples into unisolated daily driver — use $LAB VM.

Primary tools to practice this lesson: python3. Reference sites: GNU tar (https://www.gnu.org/software/tar/manual/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. RTO / RPO literacy
Recovery Time Objective: how long downtime tolerated. Recovery Point Objective: max data loss window.
Lab sets modest targets for notes and configs.
3. Documentation
Record restore date, success/fail, lesson learned in policy file.
Failed test → fix backup job — not ignore.
4. What you ship: restore test record
Restore steps + one completed $LAB test result + RTO/RPO one-liners.
5. What you record before the next lesson
Restore test log entry.
6. Wrong vs right: stranger hosts vs YOUR lab hosts
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
- Wrong: Restore old backup over production server without change ticket.
- Right: Name restore test. Next: awareness training.
Mission: restore test log
1) Restore one $LAB file or snapshot to isolated path. 2) Verify content. 3) Write RTO/RPO for your lab notes.
