TomatoUSB – selectively save/restore NVRAM settings before/after upgrading

Posted by jpluimers on 2017/07/14

TomatoUSB recommends a NVRAM reset (or 30/30/30 reset) before and after upgrades.

This means you loose all your settings which causes a lot of people to not upgrade at all.

The steps to export/import are a bit vague as they depend on what you want to save.

It basically comes down to do this on the old configuration

nvram export --set

Save that output to a local file and then use a search tool searching for specific sections you want to restore.

After you restored the sections ensure you persist them:

nvram commit

This is what the TomatoUSB author usually searches for:

nvram export --set | grep rrule1
nvram export --set | grep qos_
nvram export --set | grep dhcp_
nvram export --set | grep dhcpd_
nvram export --set | grep ddnsx0=
nvram export --set | grep lan_hostname=
nvram export --set | grep lan_ipaddr=
nvram export --set | grep wan_proto=
nvram export --set | grep wan_hostname=
nvram export --set | grep wan_domain
nvram export --set | grep pppoe_username=
nvram export --set | grep pppoe_passwd=
nvram export --set | grep http_
nvram export --set | grep router_name
