ns4 is a configuration management tool which allows the automated backup of just about anything, but it was designed for routers and switches. If you are able to log into it through a CLI, you can back it up. Commands are defined within a configuration file, and when they are executed, the output is sent to a series of FTP servers for archiving. As well as archiving configurations, it allows scripts to be run on nodes; this allows configurations to be applied en masse and allows conditional logic so different bits of scripts are run on different nodes. License: Free for non-commercial use Changes: This release contains major changes with regards to Scripts, Alerts, and Transports. It introduces support for SFTP based Transports and HTTP POST based Alerts. The scripting engine has been redesigned from scratch to allow much simpler and seamless integration with ns4.
