Introduction to Backup Server
What is backing up?
The process of copying data from one location to another
Why do you need to backup?
To prevent data loss or workflow process disruptions
To restore lost data and system
How many types of backups are there?
There are 5: Normal, Copy, Daily, Differential and Incremental.
Backup systems are composed of backup units, backup media, and software components (oh, and you, the operator).
Backup units: a tape device, a jukebox, magneto-optical (MO) drives
Backup media: tapes, cartridges, CD-WORMs (write once, read many), erasable CD-ROMs, diskettes, and more. Any device on which the backup unit stores data becomes the medium.
Software: You can use the Windows 2003 built-in backup software on a third-party backup device or you can use the software that comes with the device.
Some files that are hard-coded into NTBACKUP don’t get backed up, and you can’t change or alter this. Following are some of the files and other things that don’t get backed up:
Open files: Users can’t have files open while the backup is running. Those files won’t be backed up. Have the users log off the system and disconnect them from any shares.
Temporary files: No temporary files, such as PAGEFILE.SYS, are backed up.
Permissions: The account used to perform the backup must have permission to read files.
Registry: Only the local Registry is backed up. Registries on other servers are not backed up.

Restoring from a Backup
Backing up your data is only half the picture. The other half involves restoring files on the network.
Restoring Active Directory
Windows Server 2003 includes three types of directory services restore methods:
