Server Data backup
The Management application helps you to protect your data by backing it up automatically. Backup
is a service process that periodically copies and stores application files to an output directory. The
output directory is relative to the server and must use a network share format to support backup to
the network. The data can then be restored, as necessary.
NOTE
Backing up data takes some time. It is possible that, in a disaster recovery situation, configuration
changes made after the last backup interval will be missing from the backup.
The Management application allows you to view the backup status at a glance, initiate immediate
backup, enable or disable automatic backup, reconfigure the backup directory, interval, and start
time, and retrieve backup events.
What is backed up?
The data is backed up to the following directories:
•
Backup\databases — contains database and log files.
•
Backup\data — contains Element Manager data files (including Dump files, Data collection
progress files, Director/Switch firmware files FAF files, Switch technical supportSave, and
Switch backup files) and miscellaneous files.
•
Backup\conf – contains the Management application configuration files.
•
Backup\cimom – contains the SMIA configuration files.
Management server backup
There are three options for backing up data to the Management server:
•
Configuring backup to a CD drive
•
Configuring backup to a hard drive
•
Configuring backup to a network drive
The Management server is backed up to D:\Backup (Windows systems) by default. If there is not
second hard disk, this is a rewritable (CD-RW) compact disk. Make sure you have a CD-RW disk in
the CD recorder drive to ensure that backup can occur. Critical information from the Management
application is automatically backed up to the CD-RW when the data directory contents change or
when you restart the Management application.
Note that backing up to CD is not the recommended method. The usable capacity of a CD is
approximately 700 MB and needs to be replaced when full. Also, CD media has a limited number of
re-writes before the medium is exhausted, and write errors occur. It is recommended that you
configure the backup system to target a hard drive or a network drive as described in the
procedures below.
