Backup Windows 2003 Server

Backup is the activity of copying files or database so that they will be preserved in case of equipment failure or other catastrophic situations.


Normal 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.


Procedure to backing up the data through Normal backup:



1. Start -> Run - > type ntbackup.exe Press enter. [ It will look like this]

Now you need to click on the Add Job. You will get the following wizard. Click on Next

Select the appropriate option as per your requirement.

Select the files and folders as per your requirement for backing up the data. Click on next

After that locate the backup location where you want to take the backup & type the name of backup & Click on next

Select the Normal Backup from Drop Down List. And Click on next.

You will get the following wizard if you want to verify the data then you can choose this option. And click on next

Enter the job name and click on next.

You will get the finish wizard

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.

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.

Authoritative Backup or System State Backup
System state backup creates a backup file for critical system related components. This backup file can be used to recover the critical system components after a crash.

Which components are backed up by the System State backup?

The Registry, boot files, as well as important system files. Then depending on their availability, the following services will be backed up as well:
Active Directory directory service, Certificate Service database, COM+ Class Registration database, SYSVOL directory.
