- Deep Dive: What is Incremental Backup?
![author avatar](https://www.reneelab.com/images/avatar/en/4.png)
Summary
Incremental backup is a method that saves storage space and reduces bandwidth by only backing up data that has changed since the last backup. Unlike full backups, which copy all data every time, incremental backups start with a full backup and then only capture changes made since the last backup. This approach helps optimize backup routines, making them more efficient and cost-effective.

- Longer data restore: It takes more time for backup software to find, analyze, and collect the latest full backup and all subsequent incremental backups.
- Less data consistency and reliability: When you need to recover, the backup software analyzes the whole backup chain. If one element in that chain is corrupt, your data is non-recoverable.
