72 CHAPTER 4: BACKING UP AND RESTORING A VCX CONFIGURATION
apply the old configuration by restoring the backup file to the
upgraded system.
■ You can backup and restore the currently active version of VCX
software and the currently active version of the VCX operating system
only. Configuration files from any other versions of VCX (or its
constituent components) or the operating system which may be on
the system are not backed up. This means that, depending on the
reason for the backup and restore, you may not be able to downgrade
a restored system to a prior release.
■ You cannot modify a configuration backup file and restore it, either as
a way of changing a configuration or as a way of configuring multiple
systems with similar configurations.
■ Partial backups are not supported (for example, you cannot back up
one component or a subset of components) on a single machine.
■ Backup files are not encrypted. Backup files typically contain sensitive
information, and must be treated with care and stored securely.
■ Files that do not contain configuration data (for example, log files and
cache files) are not backed up.
■ Configuration files associated with the VCX operating system that are
not typically modified in the course of normal system configuration
are not backed up.
