Incremental vs Differential backup

DFIncBackup can do incremental and differential backup.
Both backups allow to speed up against full backup.

An incremental backup include files, which have been changed or created since
the last full or incremental backup.
For restore, it needs last full backup and all incremental backups to the present day.

A differential backup include files, which have been changed or created since the last full backup.
For restore, it needs last full backup and last differential backup.

Incremental Vs Differential Backup - Advantages:
Incremental backup takes less time and space against differential backup.

Incremental Vs Differential Backup - Disadvantages:
Incremental backup takes more time to restore from 1 full plus N incremental archives against only 1 full plus 1 differential archives.

Differential Vs Incremental Backup - Advantages:
Quick restore by only 2 archives: Full and Differential.
More secure - one differential archive can be damaged, but another differential archive allow to do full restore.

Differential Vs Incremental Backup - Disadvantages:
Every day differential backup takes more time and space than incremental backup.
