version, an cOS Core upgrade can then be performed.
The Management Interfaces Used
Both types of backup, configuration and system, can be performed either by downloading the
file directly from the Clavister Security Gateway using SCP (Secure Copy) or alternatively using
the Web Interface. Backup cannot be done using CLI commands.
Similarly, restoring a backup is done in the reverse fashion. Either by uploading the backup file
using SCP or alternatively through the Web Interface. A restore cannot be done with CLI
commands.
Warning: Do not upload a system backup to dissimilar hardware
Do not try to upload a full system backup (configuration plus cOS Core) to hardware
that is not the same model as the original.
This will cause the configuration to be automatically activated and cOS Core rebooted,
with the possibility that cOS Core becomes unreachable. Upload of full system backups
must be done to similar hardware since there is no opportunity to change the
configuration before it is activated.
Operation Interruption
Backups can be created at any time without disturbing cOS Core operation. For restores,
however, it is not recommended to have live traffic flowing since the restored configuration may
significantly alter the security policies of the security gateway.
After restoring a backup it is necessary to Activate the new configuration, as is done with a
normal configuration change.
A complete system restore will require that cOS Core reinitializes, with the loss of all existing
connections. Initialization may require some seconds to complete depending on the hardware
type and normal operation will not be possible during this time.
Backup and Restore using SCP
There are two files located in the cOS Core root directory:
• config.bak - This is the backup of the current configuration.
• full.bak - This is the backup of the complete system.
SCP can be used to download either of these files. When the download is complete the filename
will be altered to include the date. For example, full.bak might become full-20081121.bak to show
it is a snapshot of the state on November 21st, 2008.
To restore a backup file, the administrator should upload the file to the Clavister Security
Gateway. The name of the file does not need to be changed in any way and can retain the date
since cOS Core will read a header in the file to determine what it is.
