2.6.1 Backup Types
Backup Wizard provides five types of backup that define which data is backed up. Some backup types use
backup markers, also known as archive bits, which mark a file as having changed. When a file changes, an
attribute is set on the file that indicates that the file has changed since the last backup. When you back up the
file, this clears or resets the attribute.
Normal, which backs up all selected files and folders and does not rely on markers to determine which
files to back up. During a normal backup, any existing marks are cleared and each file is marked as
having been backed up. Normal backups speed up the restore process because the as the files are the
most current therefore you do not need to restore multiple backup jobs.
Copy, which backs up all selected files and folders without looking for or clearing markers.
Incremental, which only backs up selected files and folders that have a marker and then clears the
markers. Thus, if you did two incremental backups in a row on a file and nothing changed in the file, the
file would not be backed up the second time.
Differential, which only backs up selected files and folders that have a marker but does not clear
markers. Thus if you did two differential backups in a row on a file and nothing changed in the file, the
entire file would be backed up each time.
Daily, which backs up all selected files and folders that have changed during the day and does not look
for or clear markers.
