Maintenance and Service Guide7–1 7 Backup and recovery Overview Recovery after a system failure is as complete as your most current backup. HP recommends creating recovery discs immediately after software setup. As you add new software and data files, 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) the 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 the 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) might not have a recovery partition. Recovery discs are 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.
7–2 Maintenance and Service Guide Backup and recovery Creating recovery discs HP recommends creating 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 the computer does not include an internal optical drive, use an optional external optical drive (purchased separately) to create recovery discs, or purchase recovery discs for the computer from the HP website. Note the following guidelines before creating recovery discs: ■Use high-quality 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 using CDs, up to 20 discs might 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, exit the program before you have finished creating the recovery discs. The next time you open Recovery Manager, you are 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. 2. Recovery Manager opens. 3. Follow the on-screen instructions.
Backup and recovery Maintenance and Service Guide7–3 Backing up your information As you add new software and data files, back up your system on a regular basis to maintain a reasonably current backup. Back up your system at the following times: ■At 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 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 customized settings in a window, toolbar, or menu bar by taking a screen shot of your settings. The screen shot is a time-saver if you have to reset your preferences. To copy the screen and paste it into a word-processing document: 1. Display the screen. 2. Copy the screen: 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 document, and then select Edit > Paste. 4. Save the document. ■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 used will depend on the type of optical drive installed in the 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.
7–4 Maintenance and Service Guide Backup and recovery Using Windows Backup and Restore ✎Be sure that the computer is connected to AC power before starting the backup process. ✎The backup process might take over an hour, depending on file size and the speed of the computer. To create a backup using Windows Backup and Restore: 1. Select Start > All Programs > Maintenance > Backup and Restore. 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 the computer. You might be prompted for your permission or password for tasks such as installing software, running utilities, or changing Windows settings. See Help and Support. Using system restore points When backing 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. Create additional restore points to provide increased protection for your system files and settings. Create system restore points ■Before you adding or extensively modifying 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.
Backup and recovery Maintenance and Service Guide7–5 To create a system restore point To create a system restore point: 1. Select Start > Control Panel > System and Security > System. 2. In the left pane, click System Protection. 3. Click the System Protection tab. 4. Under Protection Settings, select the disk for which you want to create a restore point. 5. Click Create. 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: 1. Select Start > Control Panel > System and Security > System. 2. In the left pane, click System protection. 3. Click the System Protection tab. 4. Click System Restore. 5. Follow the on-screen instructions. Per fo rm in g a rec over y ✎Recover only files that you have previously backed up. HP recommends using HP Recovery Manager to create a set of recovery discs (entire drive backup) as soon as you set up the 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 the computer includes a solid-state drive (SSD), you might not have a recovery partition. If that is the case, recovery discs are included with the computer. Use these discs to recover the operating system and software. ✎Windows has its own built-in repair features, such as System Restore. 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 website or reinstalled from the disc provided by the manufacturer.
