Differential backup

Differential backup: A type of data backup method that only saves the changes made to data since the last full backup. This approach provides a balance between a full backup (which copies all data) and an incremental backup (which only backs up data changed since the last backup of any type), offering an efficient way to save storage space while still allowing for easier data recovery compared to incremental backups.
