request system snapshot

Syntax

request system snapshot

Description

Back up the currently running and active file system partitions on the router to standby partitions that are not running. Specifically, the root file system (/) is backed up to /altroot and /config is backed up to /altconfig. Normally, the root and /config file systems are on the router's flash drive, and the /altroot and /altconfig file systems are on the router's hard drive.

Prior to upgrading the software on the router, when you have a known stable system, you should consider issuing the request system snapshot command to back up the software onto the /altroot and /altconfig file systems. After you have upgraded the software on the router and are satisfied that the new packages are successfully installed and running, you should consider issuing the request system snapshot command to back up the new software onto the /altroot and /altconfig file systems. After you run this command, you cannot return to the previous version of the software, because the running and backup copies of the software are identical.
