Choose a copy stored in a location that survives the stated failure.

Learn the idea
A backup is an additional usable copy for recovery. If both copies are lost together, the plan may not help. This paper model states which location survives a fictional failure. A backup plan must also keep private work protected; do not share actual files to do the exercise.
Choose a usable copy in a location that survives the stated failure. If none is supplied, the justified outcome is that no surviving usable copy is established. Two names or duplicates on failed storage do not support recovery.
A drawing is saved on a separate protected backup. The main storage is lost but the verified usable backup survives: use that copy for recovery. If the only copy had been on the failed storage, recovery would not be established. An adult may read the fictional cases; no actual files need to be shared.
- Follow the worked example one step at a time. Say or draw what happens.
- Choose a copy stored in a location that survives the stated failure.
- Say which detail makes the example answer fit. Pick another answer and say why it does not fit.
- Try the question and practice questions. Read the rule again if your answer does not match the explanation.
See the method in action
A drawing exists on main storage and on a separate protected backup. Main storage fails; the backup location survives and its copy is verified usable. First cross out the failed main copy. The surviving usable backup can supply the drawing. Now compare a different case with two names on the failed main storage and no other copy: neither name supplies surviving data, so recovery is not established. Protect private copies and verify restoration in an isolated check.

Helpful tips
- Look for an explicitly supplied usable copy that survives the stated failure.
- Do not invent recovery data: an unsaved screen or another name on failed storage does not establish a surviving copy.
See the answer and explanation
No surviving usable copy is established by this record
The stated record supplies no usable copy that survives. Names or duplicates on failed storage do not survive that failure, and an unsaved screen is not a saved recovery copy. Do not invent an unlisted backup or assume exact reconstruction.
Take it further
New failure case: the main drawing is lost and a separate backup file survives, but the supplied restore check says that file cannot be read. Expected: no usable recovery copy is established; surviving storage alone does not establish a usable copy. Do not invent a replacement drawing.
