Which backup type saves all data regardless of previous backups?

• A. Incremental Data Backup
• B. Differential Data Backup
• C. Full/Normal Data Backup
• D. Snapshot Backup

Answer: (C)

In backup strategies, a full backup copies every file and data within the selected scope each time it runs, producing a complete dataset that can be restored from that single backup without needing any prior backups. This means it saves all data regardless of what was backed up before, providing a straightforward and complete restore point. While it offers the simplest recovery, it uses the most storage and takes longer to perform. Incremental backups only capture data that has changed since the last backup, so restoring requires the most recent full backup plus all subsequent incremental backups. Differential backups capture changes since the last full backup, so you need the last full backup plus the latest differential. Snapshot backups record a point-in-time image of the data, often at the storage level, which may reference existing data and focus on the state at a moment in time rather than duplicating everything anew each time. So, the type that saves all data every time is the full backup.
