Differential backups save which data?

Differential backups save which data?

• A. Files created or edited since the last full backup
• B. All files since the last incremental backup
• C. Files created since the last incremental backup
• D. Only new files since the last full backup

Answer: (A)

Differential backups save all data that has changed since the last full backup. This means any files that were created or edited since that last full backup are included. For example, if a full backup was made on Monday, the differential backup on Tuesday will include everything changed since Monday, and it will continue to accumulate changes from Monday onward. It’s not about all files since the last incremental backup, and it’s not limited to only new files since the last full backup.
