A "Differential Backup" is a type of backup where only the data that has changed or been added since the last full backup is backed up. Unlike incremental backup, which only backs up the data changed since the last backup, differential backup backs up all changes since the last full backup. As a result, differential backups are larger than incremental backups but smaller than full backups, and they allow for faster recovery compared to incremental backups.
Typical features of software in the "Differential Backup" domain include:
Selective Data Backup: The software allows for the selection of specific files, folders, or systems for the differential backup to only back up the needed data.
Scheduling: The software enables scheduling of differential backup jobs at specified times or intervals to ensure that backups are created regularly.
Automation: The software provides features for automating differential backup jobs to reduce manual intervention and ensure that backups are performed regularly and reliably.
