Backup and recovery
Overview
Recovery after a system failure is as complete as your most current backup. HP recommends that you create 
recovery discs immediately after software setup. As you add new software and data files, you should continue to 
back up your system on a regular basis to maintain a reasonably current backup.
Tools provided by the operating system and HP Recovery Manager software are designed to help you with the 
following tasks for safeguarding your information and restoring it in case of a system failure:
■Creating a set of recovery discs (Recovery Manager software feature). Recovery discs are used to start up 
(boot) your computer and restore the operating system and software programs to factory settings in case of 
system failure or instability.
■Backing up your information regularly to protect your important system files.
■Creating system restore points (operating system feature). System restore points allow you to reverse 
undesirable changes to your computer by restoring the computer to an earlier state.
■Recovering a program or driver (Recovery Manager software feature). This feature helps you reinstall a 
program or driver without performing a full system recovery.
■Performing a full system recovery (Recovery Manager software feature). With Recovery Manager, you can 
recover your full factory image if you experience system failure or instability. Recovery Manager works from a 
dedicated recovery partition (select models only) on the hard drive or from recovery discs you create.
✎If your computer includes a solid-state drive (SSD), you may not have a recovery partition. Recovery discs have 
been included for computers that do not have a partition. Use these discs to recover your operating system and 
software. To check for the presence of a recovery partition, select Start > Computer. If the partition is present, 
an HP Recovery drive is listed in the Hard Disk Drives section of the window.
Creating recovery discs
HP recommends that you create recovery discs to be sure that you can restore your system to its original factory 
state if you experience serious system failure or instability. Create these discs after setting up the computer for the 
first time.
Handle these discs carefully and keep them in a safe place. The software allows the creation of only one set of 
recovery discs.
✎If your computer does not include an internal optical drive, you can use an optional external optical drive 
(purchased separately) to create recovery discs, or you can purchase recovery discs for your computer from the 
HP Web site. 
						

							8–2Maintenance and Service Guide
Backup and recovery
Note the following guidelines before creating recovery discs:
■You will need high-quality DVD-R, double-layer DVD-R, DVD+R, double-layer DVD+R, BD-R (writable 
Blu-ray), or CD-R discs. All these discs are purchased separately. DVDs and BDs have a much higher capacity 
than CDs. If you use CDs, up to 20 discs may be required, whereas only a few DVDs or BDs are required.
✎Read-write discs, such as CD-RW, DVD±RW, double-layer DVD±RW, and BD-RE (rewritable Blu-ray) discs, 
are not compatible with the Recovery Manager software.
■
The computer must be connected to AC power during this process.
■Only one set of recovery discs can be created per computer.
■Number each disc before inserting it into the optical drive.
■If necessary, you can exit the program before you have finished creating the recovery discs. The next time you 
open Recovery Manager, you will be prompted to continue the disc creation process.
To create a set of recovery discs:
1. Select Start > All Programs > Recovery Manager > Recovery Manager.
Recovery Manager opens.
2. Click Advanced Options.
✎If you are operating the computer on battery power, you will be prompted to connect to AC power before you can 
go to the next step.
3. Click Recovery disc creation, and then click Next.
4. Follow the on-screen instructions.
Backing up your information
When to back up
■On a regularly scheduled basis
✎Set reminders to back up your information periodically.
■
Before the computer is repaired or restored
■Before you add or modify hardware or software
Backup suggestions
■Create a set of recovery discs using Recovery Manager.
■Create system restore points using the Windows System Restore feature, and periodically copy them to disc.
■Store personal files in the Documents folder and back up this folder periodically.
■Back up templates stored in their associated programs.
■Save customized settings in a window, toolbar, or menu bar by taking a screen shot of your settings. The screen 
shot can be a time-saver if you have to reset your preferences.

To copy the screen and paste it into a word-processing document, follow these steps:
a. Display the screen.
b. Copy the screen:
To copy only the active window, press 
alt+fn+prt sc.
To copy the entire screen, press 
fn+prt sc.
c. Open a word-processing document, and then select Edit > Paste.
Using system restore points
When you back up your system, you are creating a system restore point. A system restore point allows you to save 
and name a snapshot of your hard drive at a specific point in time. You can then recover back to that point if you 
want to reverse subsequent changes made to your system.
✎Recovering to an earlier restore point does not affect data files saved or e-mails created since the last 
restore point.
You also can create additional restore points to provide increased protection for your system files and settings.
When to create restore points
■Before you add or extensively modify software or hardware
■Periodically, whenever the system is performing optimally
✎If you revert to a restore point and then change your mind, you can reverse the restoration.
Create a system restore point
1. Select Start > Control Panel > System and Maintenance > System.
2. In the left pane, click System Protection.
3. Click the System Protection tab.
4. Under Automatic restore points, select the disk for which you want to create a restore point.
5. Click Create.
The System Protection window opens.
6. Follow the on-screen instructions.
Restore to a previous date and time
To revert to a restore point (created at a previous date and time), when the computer was functioning optimally, 
follow these steps:
1. Select Start > Control Panel > System and Maintenance > System.
2. In the left pane, click System protection.
3. Click the System Protection tab.
4. Click the System Restore button, and then click Next.
The System Restore window opens.
5. Follow the on-screen instructions.

Backup and recovery
Performing a recovery
✎You can recover only files that you have previously backed up. HP recommends that you use HP Recovery 
Manager to create an entire drive backup as soon as you set up your computer.
Recovery Manager software allows you to repair or restore the system if you experience system failure or 
instability. Recovery Manager works from recovery discs or from a dedicated recovery partition (select models 
only) on the hard drive. However, if your computer includes a solid-state drive (SSD), you may not have a recovery 
partition. If that is the case, recovery discs have been included with your computer. Use these discs to recover your 
operating system and software.
✎Windows has its own built-in repair features, such as System Restore and driver roll-back capabilities. If you 
have not already tried these features, try them before using Recovery Manager.
✎Recovery Manager recovers only software that was preinstalled at the factory. Software not provided with this 
computer must be downloaded from the manufacturers Web site or reinstalled from the disc provided by the 
manufacturer.
Recovering from the recovery discs
To restore the system from the recovery discs:
1. Back up all personal files.
2. Insert the first recovery disc into the optical drive and restart the computer.
3. Follow the on-screen instructions.
Recovering from the dedicated recovery (select models only)
✎If your computer includes an SSD, you may not have a recovery partition. You will not be able to recover using 
this procedure. Recovery discs have been included for computers that do not have a partition. Use these discs to 
recover your operating system and software.
On some models, you can perform a recovery from the partition on the hard drive from either the Start button 
or
f11. This restores the computer to its factory condition.
To restore the system from the partition, follow these steps:
1. Access Recovery Manager in either of the following ways:
◆Select Start > All Programs > Recovery Manager > Recovery Manager.
– or –
◆Restart the computer and press f11 while the “Press  for recovery” message is displayed on the 
screen. Then select Recovery Manager.
Recovery Manager opens.
2. Click Advanced Options.
3. Click System recovery, and then click Next.
4. Follow the on-screen instructions.
