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:
