In the manual there are the following two definitions:
Differential
A backup that includes
all files changed since the last Full save started. Note, other backup programs
may define this differently.
Incremental
A backup that includes
all files changed since the last Full, Differential, or Incremental backup
started. It is normally specified on the Level
directive within the Job resource definition, or in a Schedule resource.
Why do we need both?
It seems that a full followed by a number of incrementals would
get all the files?
Would it be that a differential in between adds some redundancy?
