Opening backup files
Stormshield backup files (.na extension) cannot be unzipped directly from a standard archive manager. Such files must be opened in advance with a decbackup utility in command line, which can be found on SNS firewalls (available in PATH or in the folder /usr/Firewall/sbin) and on the SMC server in the folder /opt/stormshield/security. Binary files can be downloaded from the MyStormshield personal area, including decbackup, with which backup files can be opened, even when the user does not have an SNS firewall.
The syntax is as follows:
decbackup -i backup.na -o backup.tar.gz [-p <password>]
The output file is an archive that includes all of the SNS firewall’s configuration files found in /usr/Firewall/ConfigFiles, as well as the directory if it is internal.
