7 Backup and recovery Recovery after a system failure is as good as your most recent backup. HP recommends that you create recovery discs immediately afte r software setup. As you add new software and data files, you should continue to back up your system on a regu lar basis to maintain a reasonably current backup .
Recovery discs HP recommends that you create recovery di scs to be sure that you can restore your computer to its original factory state if the hard drive fails, or if for any reas on you cannot recover using the recovery partition tool s. Create these discs after se tting up the computer for the first time.
Performing a system recovery Recovery Manager software allows you to repair or restore the computer to its original facto ry state. Recovery Manager works from recovery discs o r fr om a dedicated recovery partition (select models only) on the ha rd drive.
Backing up your information You should back up your c omputer files on a regu lar schedule to mainta in a current backup. You can back up your informa tion to an opti onal external hard d rive, a networ k drive, or disc s.
Using system restore points 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.
