differential backup & full backup

differential backup & full backup

first, you should make clear a concept. only the archive file can be backup.

differential backup:  don't move the archive attribute of the new increased file. For example: on Monday your new increase file is 100, Tuesday your file is 1, Wednesday your file is 1+1=2, Thursday your file is 2+1=3, Friday your file is 3+1=4.  it backup the increased file from last full backup on Monday.

incremental backup: move the archive attribute of the new increase file. For example: on Monday your new increased file is 1, Tuesday your file is 1, Wednesday your file is 1, Thursday your file is 1, Friday your new increased file still is 1. it only backup the new increased file for that day.
