44 Media Gateway Software
Backup/Restore Procedures
A backup of the Media Gateway software should be made at the following times:
After changing the Media Gateway configuration
Before performing the Online Software Upgrade (to ensure that an up-to-date
backup is available, in the unlikely event of a problem occurring as the result of
the software upgrade)
After completing the Online Software Upgrade
44.1 Backup Procedures
The software backup procedures are performed on the Active SC board and do not
interrupt the operation of the SC software.The backup file created on the Active SC
board may be restored on both SC boards.
The backup file contains complete configuration data, including IP addresses of the
SC and Media Gateway boards. Therefore you should restore the backup file on the
same Mediant 8000 system where it was created.
44.2 Backup Types
The Media Gateway software supports two backup types:
Configuration Backup – contains configuration data and auxiliary files.
Full Backup – contains software binaries in addition to the configuration data.
Configuration Backup is much smaller than Full Backup and therefore is most
commonly used. However, it can be restored only on the SC board that has proper SC
software version pre-installed.
Note: The Operating System (OS) image is not part of any backup. Therefore you
must ensure that the correct OS version is installed on the SC board prior to
restoring the backup on it. See Section 'The Operating System on the SC Boards' on
page 226 for more information.
