A differential backup specifically includes only files that have changed since the last full backup. This approach allows for efficient use of storage space and reduces the time taken to back up data compared to a full backup, which captures all files on the system regardless of whether they have changed.

The main advantage of a differential backup is that it provides a balance between the resource demands of a full backup and the flexibility needed for quick recovery. When performing a restore, you would only need the last full backup and the latest differential backup to recover all changes made since the last full backup. This methodology is particularly useful in environments where changes occur frequently, allowing for more efficient data management and quicker recovery times.

Understanding the nature of differential backups is crucial for effective data management and backup strategies, as it directly impacts the organization’s ability to quickly bounce back from data loss scenarios.
