Summary
The article provides an in-depth exploration of differential backups, a data protection method that saves all changes made since the last full backup. It contrasts differential backups with incremental backups, which only save changes since the last incremental backup. The discussion includes the benefits and efficiency of differential backups, particularly in the context of Microsoft SQL Server. The article aims to help readers determine the most suitable backup strategy for their needs by understanding the fundamental differences and applications of these backup methods.

- Faster to Perform: Performing a differential backup is quicker than executing a full backup.
- Storage Growth: Over time, differential backups can become larger than full backups, necessitating periodic full backups.
- Ease of Recovery: Recovering files from a differential backup is simpler and faster compared to an incremental backup due to its architecture.
