Backup/Restore menu
In the unlikely event that your UTM Firewall appliance should lose its configuration or require a factory
erase, you can restore a configuration stored on a PC, USB storage device, or some other safe place to
minimize downtime.
Caution: Firmware versions and model numbers are not checked when restoring a configuration. Therefore,
ensure you restore a configuration only to the same UTM Firewall appliance model and firmware version from
which you backed up the configuration.
A copy of your current configuration can also be stored on the UTM Firewall appliance itself. This is useful
for storing multiple configuration profiles, or as a quick snapshot of a known good configuration before any
configuration changes are made that cause the appliance to stop functioning as before. Configuration can
also be saved as a plain, unencrypted text file.
After configuring your UTM Firewall appliance, it is strongly recommended that you remotely back up your
configuration to an encrypted file. If the appliance becomes unresponsive and you cannot contact the
appliance, a factory erase might be necessary. A factory erase eradicates locally stored configurations.
Therefore, the locally stored configuration files should not be considered a substitute for performing
regular, remote configuration backups. A best practice is to backup a configuration remotely on a regular
basis before and after any configuration changes.
The backup/restore icon is available on every page in the Management Console.Click the icon to quickly
access the Remote Configuration Backup/Restore page. If the icon is grayed and unavailable, the backup is
current.
Local Backup/Erase page
Use the Local Backup/Erase page ( Figure 333 ) to backup and restore configuration files locally, which
means on the UTM Firewall appliance itself.
Caution: If a factory erase is performed, backup files are erased. Using Remote Backup/Restore is highly
recommended. See Backing up a configuration remotely .
Saving a configuration locally
Each local configuration backup stores a single snapshot of the configuration only; existing configuration
snapshots on the UTM Firewall appliance are not saved embedded inside any subsequent snapshots.
To create a local configuration backup:
