Filer configuration backup and cloning
About filer configuration backup and cloning
Filer configuration backup and cloning is performed using the config command. The configuration backup operation stores the filer's configuration information in a single file with a name you specify. The configuration backup file enables you to restore the filer configuration in case of disasters or emergencies. Configuration cloning enables you to clone the configuration of an existing filer to a new filer.
Backing up a filer configuration
When you use the config command to back up a filer configuration, the filer configuration is saved in a single file with a file name that you specify. By default, backup configuration files are created in the /etc/configs directory.

-f forces the new file to override an existing backup.
-v causes Data ONTAP to also back up a volume-specific configuration.
config_file is the name or the path and name of the backup file you are creating.
Example 1
The following is an example of the config dump command using the default directory to back up a filer-specific configuration to the file /etc/configs/08_02_2001.
config dump 08_02_2001
