Data backup
The Management application helps you to protect your data by backing it up automatically. 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 M-EOS switches 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 Fabric OS miscellaneous files.
• Backup\conf – contains the Management application configuration files.
Management server backup
There are three options for backing up data to the management server:
• Configuring backup to a writable CD
• Configuring backup to a hard drive
• Configuring backup to a network drive
The Management Server is backed up to a rewritable (CD-RW) compact disk by default. 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.
Back up directory structure overview
The Management server backs up data to two alternate folders. For example, if the backup
directory location is D:\Backup, the backup service alternates between two backup directories,
D:\Backup and D:\BackupAlt. The current backup is always D:\Backup and contains a complete
backup of the system. The older backup is always D:\BackupAlt.
If a backup cycle fails, the cause is usually a full CD-RW. When the backup cycle fails, there may
only be one directory, D:\Backup. There may also be a D:\BackupTemp directory. Ignore this
directory because it may be incomplete.
