Creating And Using A Backup Configuration File; Backing Up And Restoring The Configuration File Using A Remote Server - Cisco IPS-4255-K9 - Intrusion Protection Sys 4255 Installation Manual

Chapter A Troubleshooting

Creating and Using a Backup Configuration File

To protect your configuration, you can back up the current configuration and then display it to confirm
that is the configuration you want to save. If you need to restore this configuration, you can merge the
backup configuration file with the current configuration or overwrite the current configuration file with
the backup configuration file.
To back up your current configuration, follow these steps:
Log in to the CLI using an account with administrator privileges.
Step 1
Save the current configuration.
Step 2
sensor# copy current-config backup-config
The current configuration is saved in a backup file.
Display the backup configuration file.
Step 3
sensor# more backup-config
The backup configuration file is displayed.
You can either merge the backup configuration with the current configuration, or you can overwrite the
Step 4
current configuration.

Backing Up and Restoring the Configuration File Using a Remote Server

We recommend copying the current configuration file to a remote server before upgrading.
Note
Use the copy [/erase] source_url destination_url keyword command to copy the configuration file to a
remote server. You can then restore the current configuration from the remote server. You are prompted
to back up the current configuration first.

Merge the backup configuration into the current configuration.
sensor# copy backup-config current-config
Overwrite the current configuration with the backup configuration.
sensor# copy /erase backup-config current-config
/erase—Erases the destination file before copying.
This keyword only applies to the current-config; the backup-config is always overwritten. If this
keyword is specified for destination current-config, the source configuration is applied to the system
default configuration. If it is not specified for the destination current-config, the source
configuration is merged with the current-config.
source_url—The location of the source file to be copied. It can be a URL or keyword.
destination_url—The location of the destination file to be copied. It can be a URL or a keyword.
