Disaster recovery

Hardware faults can occur that require disaster recovery. Recovery happens in two steps. First restore the Linux base (including operating system) and then restore the applications.

A file system backup and restore option supports the base disaster recovery.

During a system backup the following application data is backed up and is restorable when the applications are reinstalled:

•Enterprise Common Manager data

•Subscriber Manager security certificates and CND connection details

•Element Manager data

Application configured system data

You can configure values for routes, host records, and firewall rules using the CLI commands routeconfig, hostconfig, and basefirewallconfig. These values are application configured system data. Application configured system data is backed up as part of the application data backup. For more information about Nortel Linux base CLI commands see “ Nortel Linux base CLI commands” (page 139).

Base recovery

After a successful base installation, you can choose to back up prespecified file systems (both executable binary and configuration data files) onto a USB or network Secure File Transfer Protocol (SFTP) storage device.

The following naming convention is used for the Linux base backup archive:

hostname-yyyy.mm.dd.hh.MM.ss.tar.gz

For example, hp3-e-2008.09.04.18.54.47.tar.gz is a backup archive name where hp3-e is the host name. The archive name begins with the short host name (not the FQDN) and contains the following fields, which are defined as follows:
