Cumulative Incremental Backup

What is a Cumulative Incremental Backup?
Cumulative incremental backup is a data backup process that saves data files and objects that have changed since the last full or archived backup. It is a data backup technique that only updates changed data and not the entire data.

Cumulative incremental backup is primarily a form of incremental backup that is not a differential incremental backup. Cumulative incremental backup works through backup software that can identify and manage versions of data objects. Before starting an incremental backup, the backup software looks for the last incremental level 0 backup. If the last backup is also an incremental backup, it only records changes made to the previous changes. This makes the backup process much leaner and faster than the differential backup.
