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 (R ecovery Manager software feature). R ecovery discs are used to start up 
(boot) your computer and restore the  operating system and software progra ms 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 fe ature). System restore points allow you to reverse 
undesirable changes to your computer by re storing 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 perfo rming a full system recovery.
■Performing a full system recovery (R ecovery 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.
✎Computers with a solid-state drive 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, right-click  Computer, click Manage , and then click  Disk 
Management. If the partition is present, an HP Re covery drive is listed in 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 a serious system failure or instab ility. 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 driv e, you can use an optional external optical drive (select 
models only) to create the recovery  discs, or you can purchase recovery  discs for your computer from the HP 
Web site.
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 re quired, 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 inser ting 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 Disc Creation .
Recovery Manager opens.
2. Follow the on-screen instructions.

Backing up your information
As you add new software and data files, you should back up your system on a regular basis to maintain a reasonably 
current backup. Back up your  system at the following times:
■On a regular 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
Note the following when backing up:
■Create system restore points using the Windows® System Restore feature, and pe riodically copy them to disc.
■Store personal files in the Documents library and backup 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:
1. Display the screen you want to save.
2. Copy the screen image:
To copy only the active window, press 
alt+fn+prt sc. 
To copy the entire screen, press 
fn+prt sc.
3. Open a word-processing do cument, and then select Edit > Paste.
The screen image is ad ded to the document.
4. Save the document.
■You can back up your information to an external hard drive, a network drive, or discs.
■When backing up to discs, use any of the following  types of discs (purchased separately): CD-R, CD-RW, 
DVD+R, DVD+R DL, DVD-R, DVD-R DL, or DVD+/-RW.  The discs you use will depend on the type of 
optical drive installed in your computer.
✎DVDs support store more information than CDs, so  using them for backup reduces the number of 
recovery discs required.
■When backing up to discs, number each disc before  inserting it into the optical drive of the computer.

Using Windows Backup and Restore
To create a backup using Windows Backup and Restore Center, follow these steps:
✎Be sure that the computer is connected to AC power before you start the backup process.
The backup process may take over an hour, dependin g on file size and the speed of the computer.
1. Select Start > All Programs > Maintenance > Backup and Restore Center .
2. Follow the on-screen instructions  to set up and create a backup.
✎Windows® includes the User Account Control feature to improve the security of your computer. You may be 
prompted for your permission or pa ssword for tasks such as installing software, running utilities, or changing 
Windows settings. Refer to Help and Support for more information.
Using system restore points
When you back up your system, you are creating a system re store 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 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 sa ved data files 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 chan ge your mind, you can reverse the restoration.

Recovery Manager software allows yo u 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 co mputer. Use these discs to recover your 
operating system and software.
✎Windows has its own built-in repair features, such as Syst em Restore. If you have not already tried these features, 
try them before using Recovery Manager.
Recovery Manager recovers only software that was preins talled at the factory. Software not provided with this 
computer must be downloaded from the manufacturer’s We b 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.

On some models, you can perform a re covery from the partition on the hard drive from either the Start button or 
f11. This restores the computer to its factory condition.
