Using the backup and restore utility

The backup and restore utility (BRU) provides a means to preserve the integrity of your BCM system operating system software and configuration data.

Use the BRU if you need to replace the following hardware:

•Hard disk (see “Replacing the hard disk” on page 253)

•Media Services Card (MSC) (see “Replacing data cards and processing hardware” on page 299)

Before you perform any substantial maintenance on the BCM system, save your data to a safe storage module location elsewhere in the network. After hardware maintenance is complete, restore the data to your BCM system. Access the BRU through the Element Manager main page.

For further instructions about how to operate the BRU, refer to the BCM 4.0 Administration Guide.
