8 Backup and recovery
Recovering system information
Tools provided by the operating system and 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:
●Backing up your information regularly to protect your important system files.
●Making 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...

●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.

NOTE:Recovering to an earlier restore point does not affect data files saved or e-mails created since
the last restore point.
You also can create additional restore points to provide increased...

Recovery Manager 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 on the hard drive. 
NOTE:Windows has its own built-in repair features, such as System...
