Windows Server Backup and Restore
• Windows Server Backup is new in Windows Server 2008
and supersedes NTBackup.exe
• Must be installed with Server Manager
• Some features and limitations
– Backups can be run manually or scheduled with Task Scheduler
– Separate files or folders can’t be backed up; you can only choose
which volumes to back up
– Scheduled backups require a dedicated fixed or removable disk as the
backup destination when you’re using Windows Server Backup
• Select one of the following options:
– Always perform full backup
– Always perform incremental backup
– Custom

Creating Scheduled Backups
• Scheduled backups give you the flexibility to run a
backup at a particular time of the day, once per
day, or multiple times per day
• Before using the Backup Schedule Wizard, know:
– What do you want to back up?
– When and how often should the backup occur?
– Where will backups be stored?

Backup and Restore from the Command
Line
• Windows Server Backup has less flexibility than its
command-line equivalent utilities
• Wbadmin.exe can perform all tasks available in
Windows Server Backup and more
–
–
–
–
Perform a system state backup
Recover the system state
Delete a system state backup
Restore or delete a backup catalog
• Most tasks with Wbadmin require you to be a
member of the Backup Operators or Administrators
group
MCTS Windows Server 2008 Active Directory
10
Perform a System Recovery
• If full recovery is necessary, you need the Windows
Server 2008 installation disk or access to Windows
Recovery Environment (WinRE)
• Can be installed on a server’s hard drive by
pressing F8 when the boot process starts
• Can also be accessed from the Windows Server
2008 installation DVD
• You can restore a complete backup from a local or
removable disk or a network location
MCTS Windows Server 2008 Active Directory
11
Active Directory Backup and Restoration
• Active Directory is backed up when you perform a full
backup of a domain controller or when you back up the
volumes containing system recovery information
• Restoration can be authoritative or nonauthoritative
• Nonauthoritative restore restores the Active Directory
database, or portions of it, and allows it to be updated
through replication; requires a restart into Domain Services
Restore Mode (DSRM)
• Authoritative restore ensures that restored objects aren’t
overwritten by changes from other domain controllers
through replication

Active Directory Defragmentation
• Active Directory database requires periodic maintenance in
the form of defragmentation and compaction
• Online defragmentation occurs when garbage collection is
performed
• Objects that have been deleted for more than 180 days are
removed by garbage collection
• Object marked for removal after a period of time has been
“tombstoned”
• Online defragmentation removes deleted objects but doesn’t
compact the database
• Offline defragmentation compacts the database
• Compaction is performed with the Ntdsutil program

Performance Monitor
• Uses counters to track performance of a variety of
objects
• A counter is a value representing some aspect of
an object’s performance
• Counters exist for virtually every hardware and OS
component on a server
• Performance monitor can track counters with a line
graph, histogram, or as raw data saved to a report
• Can display counters in real time or from a saved
log file

Performance Monitor (cont.)
MCTS Windows Server 2008 Active Directory
22
Collecting Baseline Performance Data
• Using real-time monitoring can be difficult since
there is no point of reference, or baseline, for
comparing data
• To create a baseline, you create a data collector
set that specifies the performance counters you
want to collect
• Performance monitoring uses system resources
• Monitoring remotely can reduce the strain on a
system

–
Performance counters
Counter alerts
Event traces
System configuration
• Common use is to create a baseline
• Predefined data collector sets can be run as they
are or used as templates to create user-defined
data collector sets
MCTS Windows Server 2008 Active Directory
25
Reports
• Reports folder contains reports generated from
data collector sets
• User Defined subfolder contains reports generated
by user-defined data collector sets
• System subfolder contains folders for each system
data collector set
• After a data collector set runs, a report is generated
automatically and placed in a folder with the name
of the data collector set
