Saving router config via ssh command line

[dave14305]

Is it possible to trigger the save of the router's configuration via the ssh command line to a locally mounted USB drive? I am envisioning an automatic monthly backup of router's config since I am pretty bad at remembering to backup my config as I tinker with features.

You could use cru to setup your cron job and get it to issue an "nvram save mybackup.cfg" command.

Thanks, I didn't realize it was as simple as that.

Hi, trying to work this out where do I find "mybackup.cfg" to transfer it to my computer?

I'm not on Merlin (yet), do I need to be? The command worked, just got to find or access the file. I don't know what SSH commands are available etc. I just did a "cat" command on it, I belive that this the linux equivalent of the windows type command and that appears to be a binary file, is there anyway to get a backup as text?

You can use John's NVRAM save utility - https://www.snbforums.com/threads/user-nvram-save-restore-utility-r26-2.19521/

That save utility was not designed for the next generation firmware ie: 382.x or 384.x and can lead to problems, to say the least.

If you just want the config for reference to look through (not for restore), you can run

nvram show | sort > myconfig.txt

If you use a tool like WinSCP you can find the files in /tmp/home/root. If you use PuTTY pscp.exe you need to specify scp mode in the parameters.
