When I do a backup, I also use the CLI to get a human-readable list of the parameters this way, on linux system foo:
ssh 192.168.1.1 nvram show >fooFileToSaveIn _________________ Six of the Linksys WRT1900ACSv2 on r38159, r40009, and r40784. On various:
VLANs, client-mode travel router, two DNSCrypt servers (incl Quad9), multiple VAPs, USB/NAS, QoS, OpenVPN client/PBR (random NordVPN server).
Quite frankly i've never had issues restoring config files from other builds. Try it and see what happens. Worst case you just have to factory reset it with the reset button and do a manual config.
I also never factory reset between version upgrades. My WRT1200AC hasn't been factory reset in well over a year and has had just about every build released in that time period installed on it. zero issues.
If you really need to get the info out of a backup, probably best to install whatever build the backup was made from to your router, do the nvram show all > outputfile.txt and then transfer that file off your router. Flash the version you want to use and use that txt file to manually restore settings.
Thanks for these replies. It has been a fairly long time since I have had to work on anything with my dd-wrt routers. So I'm foggy on using & setting up dd-wrt.
The routers in question today are ones which had been reset during a complicated power & UPS failure. But I had saved the nvrambak configs from before. It was not apparent initially what all might have happened to these routers. So I wanted to be cautious.
The list I got from the nvrambak > show was very long. & seems to contain a lot more information than I was/am looking for?
And I'm not sure how to get it from the router to my PC with telnet.
I will keep in mind the suggestion to NOT doing a "factory" reset when installing a new build. I had avoided that based on warnings on doing that from when I was first setting up my wrt3200's and wrt1200's. But that was a fair while ago and builds involved fairly substantial deep changes for those routers as the "devs" worked with the issues of getting good WiFi drivers from LinkSys.
I appreciate this help.

Whatever file you drop into /tmp/www has to have a .asp extension to be served. I am not aware of any other extensions that it handles, but you will get the text content of the file. /tmp/www will clear on your next reboot as all of /tmp is a ramdisk.
If you want to view it in a "cleaner" format view the page source "view-source:<routerip>/user/test.asp" in chrome will display it with the proper carriage returns/line feeds.
