Backup & System Image
A backup is a secured copy of files and folders
commonly saved using compression to reduce
storage size.
Backups exist so that a user can restore the files and
folders in the event of data loss.
A special type of backup is a system image.
System images are snapshots of an entire hard drive
that includes all the files and folders needed to
completely restore a computer.

How Windows Handles Backups
Microsoft provides the Windows Backup and Restore
utility with Windows 7 and later operating systems.
The Backup and Restore utility allows creation of two
types of backups:
 File and Settings
 System Image
The Files and Settings backup type exists so a user
can select specific files and folders to backup.
During a Files and Settings backup a user can also
opt to create a System Image.

Backup and Restore Utility
The utility allows a user
to backup data to one of
three locations:
Secondary Local Disk
Removable Media
Network Locations
NOTE: Starter and Home
Editions do not support
network backup.

Backup and Restore Utility
The recommended
option backs up Files
and Settings and
creates a System
Image.
Should you only wish
to create file backups
choose the second
option.
We will demonstrate
the second option.

Backup and Restore Utility
At this stage manually
select the files and
settings to backup.
NOTE: If this is your first
backup, Windows wants
to create a System
Image as well.

Backup and Restore Utility
All user files and
settings are ready for
backup.
The Backup and
Restore utility will
perform the backup
once a week by
default .
The schedule is easily
manipulated should a
user choose to do so.

Backup and Restore Utility
 Upon finishing the
prompts, the Backup and
Restore utility immediately
begins to run.
 If a Files and Settings type
was done the time of the
backup process will be
proportional to the
number of files being
secured.
 If a System Image was
included, the backup
process could take
considerably longer.

Backup and Restore Utility
Once the backup is
complete several
options become
available:
 Turn off the backup
 Change the backup
location
 Run the backup on
demand
 Change the schedule
 Restore backed up
files

Backup and Restore Utility: Restoring
Restoring files is
done by clicking
the “Restore my
Files” button.
Search or
Browse for the
desired files,
then follow the
prompts to
select where to
restore them.

Restoring Files: Another Method
Thanks to the Backup and
Restore Utility any files
backed up can also be
retrieved individually from
the Properties dialog box
in a tab called:
 Previous Versions
If you make a mistake, go
grab an old version and
start again!

12
Creating a System Image Only
Another feature of the Backup and Restore utility is
the ability to manually create a System Image.
System Images are excellent to have in case of drive
failure.
NOTE: In order to restore a System Image, a Windows
installation disc or Repair disc is needed.

Creating a System Image Only
Creating a System
Image and creating a
Repair Disc are both
begun from the same
location.
© ExplorNet’s Centers for Quality Teaching and Learning
14
Creating a System Image Only
Choose a location to save the System Image, Confirm
the settings, and Start backup.

15
Restoring a System Image
If your computer boots up, but fails to start
Windows, it is a perfect time for restoring a System
Image.
To get the System Image back on to the PC, a user
must perform a recovery boot using one of three
methods:
 Pre-installed Advanced Boot Options menu
 Windows Installation disc
 Repair Disc

16
Repair Disc
Many users do not have the first two options.
Anyone with a functioning Windows 7 machine, a
DVD drive, and a recordable DVD, can create a Repair
Disc.

17
Repair Disc
To create the Repair Disc select your DVD drive and
click Create Disc.

Repair Disc
Booting from the Repair Disc will eventually bring a
user to this menu from which the System Image can
be restored.

19
System Restore
System Restore is a tool used to roll back your
system files and applications to a time when the PC
was working.

20
System Restore
The System Protection feature of Windows creates
Restore Points for System Restore. They are:
 Used to roll back your system to an earlier point
in time.
 Created automatically on a weekly basis.
 Created any time you make a change to your
computer (installing applications or device
drivers).
 Can be created manually.

21
System Restore
Access System Restore from the Control Panel’s
Recovery applet or System applet.
© ExplorNet’s Centers for Quality Teaching and Learning
22
System Restore Settings
From the System
Protection link, System
Restore settings are
accessible.
A user can manually
create a Restore Point if
about to make a change
to the computer but
uncertain of outcome.
Configuring the automatic
settings is also accessible.

23
System Restore Settings
 System Restore can be
reduced to file backup only or
completely turned off.
 The amount of disk space
System Restore consumes can
be controlled.
 If System Restore runs
out of room it deletes the
oldest Restore Points.
 If a PC is running low on
storage space all Restore
Points can also be manually
deleted.

System Restore: Restoring
After opening System
Restore, the utility will
prompt for selection of a
specific Restore Point.
Select a point for
restoration, click Next,
and a confirmation
window will appear.
Clicking Finish in the
confirmation window
reboots the computer at
the Restore Point.

Other “Backup” Options
Windows has several
other options that
provide backup-like
fail safes.
These options are
accessed from the
Advanced Boot
Options menu.
To access this menu
repeatedly tap the
“F8” key during boot
up.

Recovery/Advanced Boot Options
 Repair Your Computer
 Windows Automatic repair solution.
 Use if missing or corrupt system files are the problem.
 Safe Mode
 Starts Windows in a limited state loading only the
necessary drivers and files.
 Great for when a software installation goes wrong.
 Last Known Good Configuration
 Boots the last configuration known by the OS to work.
 Uses settings saved in the Registry during the last
successful shutdown.

Windows Built-In Maintenance Tools
Now that we have a good grasp on the variety of tools
in place to help us with Backup and Recovery tasks let
us shift our focus to some built-in maintenance tools.
PCs often seem to slow down over time.
This is usually due to poor maintenance.
Microsoft provides tools to solve this problem.

Windows Built-In Maintenance Tools
Disk Defragmenter
Disk Cleanup
Task Scheduler
Action Center
System Information
Check Disk
© ExplorNet’s Centers for Quality Teaching and Learning
29
Disk Defragmenter
A utility that improves computer performance by
moving sectors of data on the hard disk so that files
are stored sequentially.
This minimizes the movement of the hard disk arm
thereby increasing the speed of data access.

30
Disk Defragmenter
In Windows 7, the
utility is set to run
automatically once a
week.
Solid state drives
(SSDs) differ from
hard disks in that they
never require
defragmentation (the
Samsung840 is an
SSD)
© ExplorNet’s Centers for Quality Teaching and Learning
31
Disk Cleanup
A tool that removes unnecessary files from your
computer.
It checks many locations for such files, including but
not limited to:
 Downloaded program files
 Temporary Internet files
 Files left after software installation
Unlike Disk Defragmenter it is not scheduled to be
run by default.

Task Scheduler
A tool that enables you to schedule and automate a
variety of actions.
It is possible to
 Start programs, scripts, and batch files.
 Display messages.
 Send e-mails.
You create a scheduled task by specifying a trigger
and an action.

34
Task Scheduler
Triggers are events that cause a task to run.
Actions are the tasks themselves.
There are two ways to create tasks in Task Scheduler:
 Create Basic Task
• With this method a Wizard walks you through
the essentials of creating a task.
 Create Task
• With this method the Create Task dialog box
appears in which a user manually creates the
task.
• Provides more control and options.
