A backup administrator wants a backup method that captures all selected data every time it runs, regardless of previous backups, to simplify restoration to a single restore point. Which backup type should be used?
- AFull backup
- BDifferential backup
- CIncremental backup
- DSynthetic backup
Show answer & explanationAnswer & explanation
Correct answer: A. Full backup
A full backup copies all selected data every time it runs, independent of prior backups. This makes restoration simplest since only the single full backup set is needed, though it requires the most storage and time compared to incremental or differential backups.
Why the other options are wrong
- B. Differential backups capture changes since the last full backup, not everything.
- C. Incremental backups only capture changes since the last backup of any type.
- D. Synthetic backups combine prior backups into a virtual full without a real full run.
Full Backup
A backup method that copies all selected data in its entirety every time the backup job runs.
- Simplest and fastest to restore from
- Requires the most storage space and backup time
- Often used as the baseline for incremental/differential backups
Memory trick: Full means everything, every time.
