request system snapshot (Junos OS Evolved)



On devices running Junos OS Evolved, take a snapshot of the contents of the /soft directory, which includes the running version of Junos OS Evolved.

Starting with Junos OS Evolved 21.2, for dual-RE systems, this command only runs on the local RE, and not on both REs in the system. Any data in the /var/home directory of the secondary disk is no longer overwritten.


After you run the request system snapshot command, you cannot return to the previous version of the software, because the running and backup copies of the software are identical.


This command has no options.

Additional Information

Before you upgrade the software on the router or replace one of the Routing Engines, when you have a known stable system, issue the request system snapshot command to back up the software, including the configuration, to the /soft directory. After you have upgraded the software or have replaced one of the Routing Engines, and are satisfied that the software packages are successfully installed and running, issue the request system snapshot command again to back up the software to the /soft directory.
