How many backup types in windows2003

Answer Posted / mohd rizwan

Normal/full backups All files that have been selected are
backed up, regardless of the setting of the archive
attribute. When a file is backed up, the archive attribute
is cleared. If the file is later modified, this attribute
is set, which indicates that the file needs to be backed up.

Copy backups All files that have been selected are backed
up, regardless of the setting of the archive attribute.
Unlike a normal backup, the archive attribute on files
isn't modified. This allows you to perform other types of
backups on the files at a later date.

Differential backups Designed to create backup copies of
files that have changed since the last normal backup. The
presence of the archive attribute indicates that the file
has been modified and only files with this attribute are
backed up. However, the archive attribute on files isn't
modified. This allows you to perform other types of backups
on the files at a later date.

Incremental backups Designed to create backups of files
that have changed since the most recent normal or
incremental backup. The presence of the archive attribute
indicates that the file has been modified and only files
with this attribute are backed up. When a file is backed
up, the archive attribute is cleared. If the file is later
modified, this attribute is set, which indicates that the
file needs to be backed up.

Daily backups Designed to back up files using the
modification date on the file itself. If a file has been
modified on the same day as the backup, the file will be
backed up. This technique doesn't change the archive
attributes of files.
