copy running-configuration startup-configuration
Command introduced before JUNOSe Release 7.1.0.
Saves all outstanding (unsaved) configuration changes to nonvolatile storage; an exact alias of the write memory command. Available if the router is in either Automatic Commit mode or Manual Commit mode. If you issue this command from Automatic Commit mode, the CLI notifies you that the command is not necessary, but allows you to proceed. This command is prevented during the high availability initialization state. If the command is issued during this state, the CLI notifies you of the state and requests that you try again later. There is no no version.
