What is a level 0 backup?

  Level 0 backups are also known as “full” backups. ALL data on a system is copied..  A normal backup disregards the archive bit in all files and backs up all files and folders selected, regardless of when they  were modified. 

      A normal backup is the most complete type of backup, and the only type of backup that can  be used to back up the registry 

      and other critical system files. A normal backup takes the longest amount of time to back up  and recover. 

      A normal backup clears the archive bit on all files after backing up.

What is an incremental backup?

An incremental backup is the quickest method for performing backups of data. 

An incremental backup only backs up files that have been created or modified  (their archive bit is set to 1) 

since the last normal or incremental backup. An incremental backup also clears the archive  bit (sets the archive bit back to 0) of all  files that it backs up.

An Incremental backup is copying data that has only changed since the last FULL backup.
