8 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.
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. Select Start > All Programs > Recovery Manager > Recovery Manager. Recovery Manager opens. 2. Click Advanced Options.
Backup and recovery 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. to an earlier restore point does not affect data files saved or e-mails created since the last ✎ Recovering restore point.
Backup and recovery Performing a recovery can recover only files that you have previously backed up. HP recommends that you use Recovery Manager ✎ You 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 that you create or from a dedicated recovery partition (select models only) on the hard drive.
