Backup and Recovery
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.
✎Computers with a solid-state drive (SSD) 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 Recovery 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 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.
Note the following guidelines before creating recovery discs:
■You will need high-quality DVD-R, DVD-R, 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.

Backup and Recovery
■Only one set of recovery discs can be created per computer. 
■Number each disc before inserting it into the computer 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. Click Start > All Programs > Recovery Manager > Recovery Disc Creation. Recovery Manager opens.
2. Follow the on-screen instructions.
Backing up your information
As you add 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:
■At a regularly scheduled times
✎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 periodically copy them to disc.
■Store personal files in the Documents library and back up this folder periodically.
■Back up templates stored in their associated programs.
■Save the customized settings in a window, toolbar, or menu bar by taking a screen shot of the settings. The 
screen shot can be a time-saver if you have to reset your preferences.
To copy the screen and paste the image 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.
d. Save the document:
■You can back up your information to an optional 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, or DVD±RW. The discs you use will depend on the type of optical drive installed in your 
computer.
✎DVDs 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, follow these steps:
✎Be sure that the computer is connected to AC power before you start the backup process.
