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.
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.
Backup and recovery 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.
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.
Backup and recovery 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.
Backup and recovery 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 partition (select models only) with an SSD might not have a recovery partition. If the computer does not have a recovery partition, ✎ Computers you are not able to recover using this procedure.
