What Is the Difference Between Incremental and Differential Backup?

1. What is Incremental Backup & Differential Backup?

These are two of the most widely used types of backups in modern data protection strategies. Incremental backup definition is a backup method that only saves the data that has changed since the last backup, whether that backup was full or incremental. This makes incremental backups extremely efficient in terms of storage and speed.

However, restoring data requires all previous incremental backups along with the original full backup, which increases recovery complexity.

What is Differential Backup?

A differential backup saves all data that has changed since the last full backup, regardless of how many backups have been performed since then.

For instance, after a full backup on Monday, a differential backup on Tuesday will include all changes since Monday. A Wednesday differential backup will include both Tuesday’s and Wednesday’s changes.

Compared to incremental backups, differential backups grow larger over time but simplify restoration because only the full backup and the latest differential backup are needed.

2. Incremental vs Differential Backup: What’s the Difference

When comparing differential vs incremental backup, the key differences lie in speed, storage efficiency, and recovery complexity. Choosing between them depends on your priorities, whether you value faster backups or easier recovery.

Now that you know the differences between the two, let's explore the pros and cons of these different backup solutions.

More FAQs about Incremental vs Differential Backup

Q1: What are the 3 types of backups?

The three main types of backups are full, incremental, and differential backups. A full backup copies all data, while incremental and differential backups focus on changes since the previous backups. Each method serves different purposes depending on storage, speed, and recovery requirements.

Q2: What are the cons of incremental backup?

Incremental backups can be difficult to restore because they rely on multiple backup files. If one file in the chain is missing or corrupted, the entire recovery process may fail. Additionally, managing long chains of incremental backups can become complex over time.

Q3: Which is better, incremental or differential backups?

The answer depends on your needs. Incremental backups are better for saving storage space and performing frequent backups quickly. Differential backups, on the other hand, are better for faster and simpler data recovery, making them ideal for critical systems.
