Choose storage based on workload and protect important data from one-device failures
Goal
You should be able to demonstrate the result described in the lesson and explain why each step was necessary.

Step-by-step
01
Classify data
Separate replaceable downloads, application data, configuration, and irreplaceable personal files.
02
Use SSD/NVMe for active workloads
Databases and virtual machines benefit from low-latency storage.
03
Keep backups elsewhere
A second partition on the same drive is not a failure-domain separation.
04
Automate copies
Use scheduled tools and verify exit codes/logs.
05
Test restores
Recover a sample directory or service periodically.
Verify before moving on

Troubleshooting
If a command or screen differs from the lesson, stop and verify the version you are using before forcing a change.
What you learned
You now understand the purpose of this part of the system and have a concrete result you can verify before continuing to the next lesson.
