Dell recommends that you perform the following procedures in the order presented.

Before You Begin

To avoid losing data during problem troubleshooting and resolution, Dell recommends that you back up your
system files before troubleshooting the problem with your PowerVault 735N system using conventional
backup methods, such as a tape drive.

In the event that the Windows® Powered operating system becomes inoperable, you can use the Dell
PowerVault 735N Systems Reinstallation CD to reinstall the operating system. Once you have reinstalled the
operating system, the system configuration information can be restored if a system state backup is available.

NOTE: For more information on backing up your system files and recovering from a system failure,
see "System Recovery, Backup, and Restore" in the Dell PowerVault 735N Systems System
Administrator's Guide.
