Configuration store - where?

[Carlos M.]

Hi, I'm trying to understand how works this firmware in order to manage everything that I need and prepare an estable workflow.

One thing hard to understand for me is wher the configurations are stored.
I would like to know what configuration is stored in the NVRAM and what is stored in other place (where?)

I know after read some threads that to keep some configurations I must use the NVRAM backup tool and other configurations with the backup tab into the GUI.

Could somebody show me the right way?

Thanks in advance!!

OpenVPN keys and certificates are in the jffs filesystem. Everything else is in nvram.

Thanks RMerlin. Just two qustions more:

- Where is placed the jffs filesystem? I thought was also in the NVRAM.
- When I use the "save" tool under administration tab... I do a backup of the NVRAM? If, yes... why the "NVRAM backup tool?

Thanks a lot!!

JFFS is a portion of the flash that is formatted as a writable filesystem.

The NVRAM backup tool is more intelligent. The router's built-in simply dumps the entire content, while the tool offers more options, cleans up some specific obsolete entries, etc...

Then... the built-in tool get the all the content/config including the port forwarding list, manual ip list from the DHCP and the guest wifi set up?
I look for a "clone" of a configured router to upload to a second one. I've two N66u with the latest fw and want to configure one and do the work for both

Thanks mate

The built in save/restore is specific to particular router, you can't use the file on a different router (it contains things like MAC addresses which can't be transferred).

You can use my NVRAM save/restore utility to do what you want using the migration mode (see the Quickstart file). This utility can ignore the router specific and firmware specific NVRAM entries.

But... I've exactly same routers (N66u), same fw version with same WAN ISP config to get my dynamic IP and just the DDNS alias change.

Just one dubt, built-in tool offer one backup for the router config and other one for jffs. The NVRAM baackup tool will get everything?

Thanks

Yes, but the internal MACs are different between the routers.

The 'save' portion will save both NVRAM and jffs. The 'restore' is two separate operations (commands).

But... NVRAM backup tool is a CLI based utility...??

Yes, it's meant to be run from a USB stick plugged into the router where it will also save all the backups (it keeps datestamped versions)
