A company has implemented a new data backup policy that includes using various methods for backing up user data. If the company chooses to implement a differential backup strategy, which statement best describes how this method functions?
It necessitates multiple backup versions for complete data recovery.
It captures changes made since the most recent backup, including all types.
It captures changes made since the most recent full backup.
It captures changes made to user files at specified intervals.
A differential backup captures changes made since the most recent full backup, ensuring that only the necessary data since the last complete backup is preserved. This method provides an efficient way to recover data without duplicating information that has already been secured.
The other options either mistakenly describe how differential backups work or confuse them with different backup approaches, which can hinder accurate knowledge of data recovery processes.
