A small business owner wants a backup strategy where every file and folder on the server is copied in its entirety each time a backup runs, regardless of whether the files have changed. Which backup type is being described?
- AIncremental backup
- BSnapshot backup
- CFull backup
- DDifferential backup
Show answer & explanationAnswer & explanation
Correct answer: C. Full backup
A full backup copies all selected data every time it runs, regardless of whether files have changed since the last backup. It takes the most storage and time but provides the simplest restore process.
Why the other options are wrong
- A. An incremental backup only copies data changed since the last backup of any type.
- B. A snapshot backup captures the state of a system at a point in time but is not the term for copying all data every run in this context.
- D. A differential backup only copies data changed since the last full backup.
Full Backup
A backup method that copies all selected data in its entirety every time it is performed.
- Simplest to restore from since only one backup set is needed.
- Requires the most storage space and time to complete.
- Often used as the baseline before incremental or differential backups.
Memory trick: Full backup packs everything every single time, like repacking your entire suitcase.
