What is an Incremental Backup?
An Incremental Backup is a data backup method that captures only the data that has changed since the most recent backup, whether it was a Full Backup or a Differential Backup. This approach minimizes storage usage and reduces backup execution time, making it highly efficient for large-scale environments.
Unlike Differential Backup, which accumulates all changes since the last full backup, incremental backups create a chain of smaller backups. While this improves efficiency, it introduces complexity in recovery, as multiple backup sets must be restored in sequence.
What is an Incremental Backup used for?
Incremental backups are used to optimize storage and backup performance while maintaining data protection. They are commonly implemented as part of a broader Business Continuity Plan (BCP) and Disaster Recovery Plan (DRP), especially in environments with frequent data changes.
However, recovery processes can be slower and more complex, impacting Recovery Time Objective (RTO). Organizations must carefully balance efficiency with recovery requirements such as Recovery Point Objective (RPO) when designing backup strategies.
