How many backup types in windows2003

Answer

Types of backup:-

The Backup utility supports five methods of backing up
data on your computer or network.
Copy backup


Copy backup

A copy backup copies all the files you select, but does not
mark each file as having been backed up (in other words, the
archive attribute is not cleared). Copying is useful if you
want to back up files between normal and incremental backups
because copying does not affect these other backup operations.


Daily backup

A daily backup copies all the files that you select that
have been modified on the day the daily backup is performed.
The backed-up files are not marked as having been backed up
(in other words, the archive attribute is not cleared).


Differential backup

A differential backup copies files that have been created or
changed since the last normal or incremental backup. It does
not mark files as having been backed up (in other words, the
archive attribute is not cleared). If you are performing a
combination of normal and differential backups, restoring
files and folders requires that you have the last normal as
well as the last differential backup.



Incremental backup

An incremental backup backs up only those files that have
been created or changed since the last normal or incremental
backup. It marks files as having been backed up (in other
words, the archive attribute is cleared). If you use a
combination of normal and incremental backups, you will need
to have the last normal backup set as well as all
incremental backup sets to restore your data.


Normal backup

A normal backup copies all the files you select and marks
each file as having been backed up (in other words, the
archive attribute is cleared). With normal backups, you only
need the most recent copy of the backup file or tape to
restore all of the files. You usually perform a normal
backup the first time you create a backup set.
