Learning objective
Explain cloud, storage, and backup, reproduce the worked example and justify a decision in the case study.
Before you begin
Troubleshooting and support
Understand
Cloud services provide remote resources; an independent backup protects against loss, failure, or error.
Worked example
Synchronization is not always a backup if deletion spreads everywhere.
Analysis and common mistakes
A useful backup has recoverable history and is restore-tested. Synchronisation often propagates deletion. Recovery objectives define acceptable data loss and downtime.
Case study — reasoning
Accidental deletion syncs to two devices. An independent dated copy can recover an earlier state; two synchronised copies do not guarantee that history.

Summary
